BTW, if you haven’t guessed, We’re just having some Machinists fun… It’s an age old Machinists argument… and we’re eating popcorn and enjoying everyone’s opinions. Truthfully, we respect both and that’s why we always put up numbers in both Imperial & Metric in all videos. So everyone can learn and Rise to Greatness!!! BOOM!!!

Mate. Cars came from Germany The First telephone was in 1849 in Italy by a Italian inventor. The First Refrigerator was invented by a French Man in 1859. The Telegraph was invented by a British man named Sir William Fothergill Cooke and Sir Charles Wheatstone in 1837. The First real steam engine also come from the English in 1698. 78 years before the american Nation ever existed. The first practical and widely used sewing machine was invented by Barthélemy Thimonnier, a French tailor, in 1829. The Combustion Engine was inveted by a German named Karl Benz. And About the imperial System. Even NASA which landed on the Moon uses the Metric System. The Imperial System only makes more sense to you because you have lived with it for your entire life Barry. For most of the World metric is more Familiar. Even for Everyday measurements, you have the centimeter, the Decimeter, the meter. And i dont know about you guys, but the average person living outside of the us will be able to understand the number 30 in the words 30 centimeters. Even now allmost all parts that the declining us Manufacturing Industry is making for the rest of the world is a metric Design converted into Imperial Numbers. I mean i know the Research and Production Quality isn't that great on this KZfaqchannel. Even the American Education system is not that good for the general Population. But still, even 5 minutes of research would have been able to prevent half of your embarrassingly wrong statements in this video.

Soo… A machinist, focused daily on absolute precision, is arguing for imperial because it’s easier to visualise/estimate in day to day life? Might want to reconsider that one…

I love how he starts by saying «just because we have always done it this way doesnt mean we have to keep going», and ends by saying «we have always done it this way, so its better!»

The automobile and both diesel and petrol engines were invented in Germany, the steam engine and locomotive were invented in the UK, the sewing machine was either invented in England or France depending on how one defines it. The incandescent light bulb was first patented in England and the telegraph was invented in France (optical) and England (electrical). The refrigerator was invented in Scotland and the first commercial refrigerator was designed by Scottish expat in Australia.

I (german engineer) cannot watch this without getting more and more headache 😂 good one, expecially with the American inventions

Are you aware the US imperial system is actually based on metric units? I work in both systems - imperial is just familiarity yet I now find metric easier. I can visualise in both systems. Although you say you have fought "we've always done it that way" you then go on to justify imperial based solely on "we've always done it that way" so can't change! None of the innovations you list depended on the use of imperial units - measurements are just measurements - they're not imagination or hard work.

“Its easy to visualize since its 6 adult feet end to end”, this one really cracked me up

Here in the U.S., my introduction to the metric system was in grade school in the 70s. Later, as a handyman and machinist working with anything metric was an annoyance. However, in recent years I'm starting to notice just how widely used it is here for various products and purposes. I've become familiar with both systems and I'm thinking that in a couple more generations, the imperial system may become the annoyance. I also discovered when trying to position fixtures, pictures, etc... on a wall, it's a lot easier with a millimeter measuring tape.

I am a Machinist in Germany and i know pretty accurtately what a milimeter, centimeter, decimeter and meter looks like. The fact that the metric system isn´t based on your everyday objects doesn´t make it less convenient, its just habitual. And there are stil things in our enviromet that are reference points, doors for example are roughly 2m in heigt and the easy transition from m to dm to cm to mm makes your life verry easy. For me its a a non argument to say that the system based on everyday things is more convenient because metric folks everyday things are the same, its just a different number on the scale or caliper, you get used to it and in the end of the day both systems work it doesn´t cange anything about the manufacturing requirments or capabilitys needed, you just type in a different number and thats it. Personal note: everytime i need to cut a imperial thread i go crazy because i have to type in a number with that goes 3 digids beyond the decimal, i would go nuts if i had to do this all day, i like my metric threads. M6 thread? turn to diameter 6mm. M12? 12mm. 5/8" thread? uuuuuuuuuuuuuuuuhhhhhhhhhhh.....(googles it)15,875mm? As i said it´s just habitual but you imperial folks really get to my nerves i moments like this and i know its the same the other way around ;D

I've used both systems for 18 years and the metric system is easier in machining & the example I'd site is with tap drill sizes. M16x2 = 14mm, M20x2.5 = 17.5 M48x5 = 43. Try doing that with imperial threads 1/2 - 13 = 27/64, 3/4 - 10 = 21/32, 1-1/2 - 6 = 1-21/64. Then you get into hole making with letter, number and fractional drills, what is the size of a letter C drill? Or a number 19 drill? What is the decimal equivalent to a 39/64 drill? You always need a drill chart which don't need to exist in the metric system. It wastes time to have to look at drill charts and measure drills constantly. I'm not a fan at all of the imperial system of drills.

I'm from Italy and honestly I find much more sense in the concept of a system of measurement that's indipendent from day to day variability. You suggested a teaspoon for example, but my teaspoon is probably different from yours. The metric system shines in ease of use to go from a order of magnitude to another and repeatability of measures.

Americans: water is 8.38lb per gallon. Meanwhile rest of the earth: 1kg is 1liter.

There are two kinds of country: Those who use the metric system And those who have disintegrated a Mars probe because they got confused with their own measuring system

From someone who works heavily in imperial units I can easily say Metric is far superior. In fact ALL other major units are derived from basic Metric units such as Volts, Amperes, Resistance, Energy (Joules), Watts, Hertz, Time(seconds). In terms of measurements of distance, fractional measurements are to confusing. 1/32 or 1/64 is not something easily translatable, where a metric scale is very very clear, where all subdivisions are scaled by 10.

In CNC machining you have a choice to run INCH or MM. Most CNC’s in INCH have a 4 place resolution (0.0001). When you switch the machine to MM you have a 3 place resolution (0.001). 0.001MM is smaller than 0.0001 INCH. By switching your machine to metric you can instantly make your CNC 60% more accurate.

I am a Kenyan machinist and even the abbreviation of some imperial units suck .How do you abbreviate pound as lb and ounce as oz ??

"Why tell a cook to add 12 grams of salt when you can tell him to add a cup". My brother is a cook and he absolutely DESPISES spoons and cups because they scale up awfully. If a recipe has to be multiplied 50 times for a large group, adding in 50 teaspoons is a pain while you can simply use weight measurements and multiply that by 50.

metric is so easy dude, 10mm is cm, 100cm is a meter, 1000 meters is a kilometer, now how many inches in a mile hmm?

"There are two kinds of countries. Those Who use metric and these who landed on the moon." Well, I guess the USSR used metric, when they send Lunik 2 to the moon.

There are two types of countries: One use metric The other sends their children to school in bulletproof vests

I think many forget the reason why america caught up so fast is because unlike Europe they didnt get bombed to oblivion twice and had to rebuild Fun fact also, the equipment and crew that worked on the apollo missions used metric

Okay so Barry just hasn’t been exposed to the Metric system enough to learn to use it effectively. He’s had a lifetime of experience using the imperial system and I bet if he had Al of his experience but in Canadian or European shop, this video would have been about the metric system and not the imperial system.

As a physicist this video triggers me on so many levels it's beyond imagination... And I'm used to multiple different unit systems.

I think the imperial system is simply there to keep less people accessible to more difficult engineering based jobs. Mexico and Canada uses metric. You need to have an engineering mindset to be able to do the imperial calculations. I think, as soon as US switches to metric, any 9th grader can start doing CNC machining with very little training.

I have been an American Machinist for 25 years today and switched over to metric 6 months ago maybe less. I was interested in improving my precision by taking advantage of the higher resolution that this allows when you are in G21 vs G20 on a CNC machine. I can honestly say that I wish I personally had switched over to Metric many years ago. in short things like old-school Cadilac, gages are far easier to read with those Dial counters on them. many people think it's obvious if there is an inch difference between 16 and 17 inches however sometimes it isn't so obvious and I have personally been off by one inch before on larger dimensions over 6 inches. interpolated bores are far easier to nail size-wise due to the increased precision of the machine. I personally spend a lot of time designing assemblies and have really been helped out by the fact that with metric I don't have to commit to a hard and final size on a fit. it is easier for me to slowly come into the right amount of clearance to get the right amount of slop in a mating assembly. I could go on. As a designer, I am a lot more able to work next to existing products that are almost always metric. Honestly, I still use both especially when I am threading. Even though it is a slight improvement overall I can honestly say that I really did not regret making the switch.

This guy is who teachers think writes Wikipedia pages

Karl Benz invented the Automobile in 1884 in Germany. Thomas Davenport invented the first electric motor in 1834 in England. The Assembly Line goes back to at least the Venitian Arsenal in the 12th century in the Serene Republic of Venice. Francis Ronalds invented the first electric telegraph in 1816 in England. Hero of Alexandria built the first Steam Engine in the first century CE in Roman Egypt. The commercially successful steam engines were developed by Thomas Savery, Thomas Newcomen and James Watt in England, England and Scotland respectively between 1798 and 1775. Barthelemy Thimonnier invented the first Sewing machine in 1830 in France. Modern Cities were the work of a variety of architects and planners in numerous countries through the 19th and 20th century. James Harrison built the first refrigeration system in Australia in 1851. Barry has demonstrated that he has no understanding of the actual history of science and engineering.

So, to sum up the ''argument'' presented in this video, we have : 1) "The US has made a lot of innovations while using the imperial system." > Total fallacy; the merits and efficiency of a measurement system are independent from the achievements of those using it. The US did not accomplish what it has accomplished thanks to the imperial system, but rather in spite of it. Also, it is worth noting that even in the US, scientists, a.k.a. the people responsible for the hereby mentioned innovations, generally use the metric system. 2) "Imperial units make more sense in day to day life because they refer to commonly used objects and are thus easier to visualize." > This is like saying "English makes more sense than Japanese because I, an English speaker, hear English words every day." If you were raised using the metric system, you would be very much able to instantly visualize a 45cm screen, a 10cm phone or a 1.85m tall person. You don't need body parts or other objects as reference points if you're simply familiar with the metric units. 3) "Everything we have already uses imperial, so it would be too expensive and too difficult to switch." > This argument is just a lame excuse. Yes, change is often difficult and can often be expensive, but it is also necessary when something better comes along. It is also possible to imagine a gradual transition, which would render the negative impacts more manageable.

As an engineer I'm going to respectfully disagree Barry. I can easily visualize what a cm, meter, cubic meter or a liter is, because that is what I've grown up with. I can't visualize at all what an 11/16" socket is and I have no idea what to look for, but a 10mm ? Easy. It's just a matter of what you are used to working with. I don't buy the "we invented some cool stuff" argument either, as none of the things you mentioned requires a specific standard of measurements and Europe, as a whole, has an extremely long list of inventions and scientific achievements as well. I don't understand why people get so attached to a system of measurement and get so defensive about it. I can understand why a change to metric is difficult and would take time as several generations would need to grow up with it to completely switch. In the end, it's just about whatever works for people. As long as we can all agree to manufacture things according to specifications. I mean when I specify something, and I always do it in metric as I am European, I don't really care if the people producing the parts are working in imperial or not, so long as the end product complies with my specifications.

Milli is 0.001 of a meter, not 0.0001 2:09

Why can’t you buy a quart of soda? Resistance is futile, you will be assimilated. In the meantime I set my DRO to metric when needed. 🎃

Jòzsef Galamb was one of Henry Ford’s main engineers that helped him design the Model T. He was Hungarian and had to convert everything from metric to imperial.

Started my machining apprenticeship in 1986. My training was all imperial units. These days I work almost exclusively in metric because it's what aerospace here works in these days, and even legacy stuff I convert to metric when working.

As a native "metric guy" it is hard for me to visualize the imperial measurements. Some are quite intuitive because in Europe we still use them (ie. in piping, rough lumber etc.) but luckily we are slowly transposing them to metric system as well. I work in food sector so I mostly making calculations of volumes, flows, pressures, temperatures, densities etc. In metric sytem (or to be more precise - International System of Units) is easy and intuitive. Some example? Please design a cuboid container that will hold 1 liter of water. Easy 10x10x10 cm, because 1 l is 1dm^3 (1000 cubic cenitmeters). Please do the same for 1 gallon (which is quite common measure like liter in Europe). Some hint? 1 cup is 14.4375 cubic inches and there are 16 cups in a gallon. Did it hepled? If you done the math correctly, one gallon is 231 cubic inches. So easy to remember and to visualize. I can agree that measuring some simple dimensions (thickness, distance from A to B, diameters etc.) it can be good enough to use imperial, but in more complex calculations it is problematic.

One inch is 3 corn grains 😂 this is sooo accurate 😂 now develop habit based on this measurement and exclude everything better😂

Americans : "It's better because we use it" Rest of the World : "Do you have a gun ?" Americans : "A 9 mm"

You mentioned that 1 m is 1000 mm, but did you mention that 1 foot is 12 inches, 1 yard is 3 feet, 1 mile is 1760 yard ... And same thing with area, volume, mass, all of them are just strange numbers. Ok, you can just learn them, learning is a good thing, so now you know all of them, could you please tell me how many yards are in 50 miles? How many cubic inches are in 4 cubic yards? I don t even want to try to calculate than on a calculator, not to say in my head. How many meters are in 527 kilometers? 527000 meters. 1 cubic meter is 1000 liters, 1 liter of water is about 1 kilogram, 1000 kilograms is 1 metric ton, 1 ton of water is 1 cubic meter. 1 meter cube has a side which is 1000 mm, 1000*1000*1000 is 1000000000 mm (just count zeros). I m 189 cm and my brother is 1,85 m, I used different units, but you can easily see that i m only 4cm taller than he is even without changing units.

conversions in the imperial system are way more complicated than in metric. How many liters fit in a cubic meter? right 1000 liters. How many gallons will fit into a cubic foot? 0.133681. how many meters is a kilometer? 1000m. How many foot is a mile? 5280 foot. These are just examples btw.

Base 10 is a lot easier to work with than base 12 when making calculations, inches gets worse when you have fractions and decimals and you have to convert between them. Mm or cm are also finer methods of measuring metric that can give you more accurate whole number approximations. I switched to metric when I started 3d printing (mostly due to the software being largely developed in Europe and Asia), but I haven't really looked back since using 4-5 decimals as opposed to 1 or 2 which is all that's required for most metric prints. At least in CAD you notice a huge boost in speed because you aren't copying 5 digits place to place, you just say 4.5mm instead of .187 inches. On larger objects things skew more, but most household objects are made around the metric system, so while a measuring cup may have teaspoons and tablespoos, I don't know how many objects I could grab and say "this is exactly 5 inches long", to be fair you can't do it with metric either however that takes away most of the advantage of imperial being able to use references to get a decent idea of a dimension. Overall they both stack up largely the same but I think I could metric is faster to design and check parts with.

You should have one of your fanuc based machines (not sure about others) run a complicated part (ie: 50-100k+ lines of code) in imperial, and then do it in metric, and see which is faster. Most, if not all, cnc machines use metric encoders and are translated back to imperial. That takes computing time. Every single line, takes longer to read and convert, than to just use metric to begin with. I would think someone who prides themselves on being efficient would understand that. You know money? That currency also based on the metric system? You use metric every day. Don't be naïve. G21>G20

Hey that was hilarious, you almost got me. Well done.

I don’t think there’s a single solid argument here for why one is better than the other; they aren’t. As someone who can visualise both Imperial and Metric measurement systems and uses both interchangeably in everyday life I can honestly say that I prefer metric because that’s where I started just as anybody would prefer to speak in their native language.

As a German I agree: I have absolutely no understanding of how long a meter is. Every time I need one I travel to Paris and get it the platinum standard out of the vault. Same for the kilogram. It's quite inconvenient. I heard others saying: "dude, one stride is about one meter. Doors are 2m high! One carton of milk has the volume of one liter!" But what do they know?! I bought some of these "spoons" and "cups" via Amazon from the US so that I could finally bake a New York cheese cake from a original US recipe. Quite convenient. Now I can also use them for eating food and don't need to get a shower anymore every time I'm finished.

Honestly, this video is just a demonstration of how stubborn some Americans can be when it comes to something better than what they currently use.

Sorry Barry, loved the video but METRIC is still better 😂😂

I'm Canadian so metric and imperial are interchangeable. We also use 3 different standards for date systems. mm/dd/yyyy, dd/mm/yyyy, yyyy/mm/dd. We just go with the flow. Personally, I even do carpentry in a mix of imperial and metric. I design it using imperial, but if I need to cut something to size it's easier for me to quickly look at and remember 120.8cm instead of 47 9/16". I find it's easier to re-find the measurement on the tape measure.

I was born in Canada in 1966, so I initially learned the British Imperial System, then began learning the Metric System in the late 1970s, and then immigrated to the US in 2000 so I then needed to learn the US Customary System. I can say of the three the Metric System is by far the best! You talk about the cost of the US switching to the Metric System but you ignored the cost of supporting two systems! There was a NASA Mars mission that failed because of a conversion error and a commercial jet that needed to make an emergency landing because it had only half the required fuel because of conversion error! That is why American scientists and engineers have all switched to the Metric System and all US Customary System units are officially defined in terms of Metric units! When Americans go to the grocery store everything is listed by law in both US Customary and Metric and when buying medicine that is likely to be in Metric. So in a sense the US is already on the Metric System but most Americans don't realized that to be the case.

I'm unconvinced. Your cup example is actually a good point. Cups can come in different sizes... I hate getting a recipe that tells me to add a cup of flour. Am I adding 330ml or 568ml? Because I've got cups in both of those sizes, but both are cups. The net result of what I get at the end will be entirely different. On the contrary, if I am told to put 400g of flour into the recipe, I know I don't need to be too accurate, but even if I go 20g over or under I'll be much more close to correct than with "a cup". Higher precision is more information, basically. Why would anyone think having less information is an advantage?

I've never once used a tea spoon or cup to measure anything while at work. Everyday I have to switch back and forth between Imperial and Metric. And Metric is hands down better. Especially when it comes to drills and reamers.

It is not wise to say that the imperial system is more intuituve because everyone can visualize how long "a foot", or how much "a table spoon" can hold, because everyones feet is different size and not every spoon is the same. Its all arbitrary and the metric system was created for this reason, to remove the human sentiment from measurements. In processes where precision is neccessary, you have to rely on precise units, and thats the reason why Imperial Units are based on Metric Units. About the cost of change, thats a fair point.

You said some nice points about why they are not gonna change, but i don't think the imperial system is better to visualize, i live in brazil and used the metric system my entire life, if someone says their height, i instantly can imagine because i've seen it a lot. When i was learning to measure in the imperial system with an analog caliper i felt the fractions really counter intuitive, and also had to "translate" to metric so i can imagine what's about. Overall it's nice to see how someone from the other system thinks!

"a milimeter and a centimeter are to small and a meter is to big" decimeter: am i a joke to you?

Ok Barry. It's useful in day to day work. when it comes to precision work imperial is the most horrible units to work with. The whole world is based on the metric system right now. including the base units of the imperial system. Missed your mark on this one.

The imperial system is crap, and is no easier to visualize than metric, on the contrary. The one argument that I agree with is that imperial measures are closer to every day usage, but that only means that we could get some names for derived units that still present clear metric measures. There's no reason to use an inch when we could use something that measures exactly 2.5cm or even 5 cm and then get the benefit of easy operations without any loss in precision. But in saying that, we also already have it, since 5 cm is an easy unit of measure anyone can picture, and half of that is the same, all we're missing is funny names for it. The height example is the worst one, because feet are so inconsistent in size, whereas 2m is a very clear measurement, and you know that most women are about 160cm and men about 180cm. Adding or subtracting inches from that is more painful than decimeters.

I grew up moving frequently inside and outside of the U.S. bouncing between imperial and metric. when work came around in highschool I did a lot of work on construction sites that used imperial, now I have a background in product development and teaching. I found myself gradually favoring metric between the two more and more. I could consider pros and cons for each but metric seems easier on a brain that prefers to think in bundles of 10, 100, 1000. I thought about this in my statistics class that didn't use these measurement systems but preferred bundling bins of numbers in the same fashion because it is easier on the human brain. much akin to metric. i like imperial to quickly communicate bit sizes or sizes of holes and whatnot but even then it's not that much easier

The fact that you proceed to show English buses for metric system even tho they don' use it makes a perfect illustration that you don't know anything about what you are saying.

Canadian CNC machinist here so i work with both. Just take a look a any imp/metric tap and drill size chart and tell me again, which one make more sense. You can defend a system that use units that most of the times have no relation with one another ie; foot vs mile but in the end, your brain dont have to fly 1000 yard per hour to understand wich one is simpler and more effective.

This is a weird take for this channel... was hoping for a 'gotcha' in the end 😔 Metric is all around you. Your electricity is metric. Your soda cans are metric. Your so-called "health care system" is metric (drugs) Your entire military is metric, etc... Metric is coming for you Barry, you better hang on 😀 Also, you didnt mention America already tried switching to metric back in the 70s, but found it too difficult to implement. Sweden switched from driving in the left-hand side to the right-hand side in 1 day without incident. Meanwhile the Muricans cant count to 10 🤣

The comments are right. The only accurate reason you gave about why the USA still uses imperial is because everything has been made in imperial and it is unfortunately impractical to change that at this point.

This argument reminds me of an Information Technology idiom… “What’s the best thing about standards? There’s so many to choose from” At its core that’s what the metric system was designed and implemented to solve. No one is asking America to switch /tomorrow/ or to legally go back and adjust drawings for everything in the past. Just come around to what the vast majority of the rest of the world is using.

Let's just say it's all about what you are used to.

Don't take this comment as hate on your channel or on Titan CNC. I pretty much love what you do here on youtube. Teaching and encoruaging people to learn is invaluable but.... This video is as imprecise as the imperial system.... First automobile: Benz Patent-Motorwagen Lightbulb: Edison improved on the filament, the lightbulb as is already existed. Refrigerator : Scottish professor William Cullen designed a small refrigerating machine in 1755. Steam engine / steam locomotive: Thomas Savery was an English inventor and engineer. He invented the first commercially used steam-powered device. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century Sewing machine: the invention of the first sewing machine, is generally considered to have been the work of Englishman Thomas Saint in 1790 Internal combustion engine: The first commercially successful internal combustion engine was created by Étienne Lenoir around 1860 (french / belgian). Modern cities:.........define modern. At this point i don't know if this video is a complete troll or a glorification of MURICA! Some other "glorious" moments in the video: 4:18 Didn't know a "spoon" was a unit of the imperial system. 4:48 If you consider "adult human feet" easy to visualize, you should stop looking at people's feet, you kinky boy. As i said, i'm not hating on you guys but, as you well know in your day to day job, precision is paramount and the "margin of error" is way to big this time. Much love.

The great debate that'll be around for many years after I'm dead 🤣

Imperial is part of your culture and you must be proud of it. That's right. But its difficult and not really precise like metric system... One thou (imperial), in metric, is usually a bad tolerance, not a goal. And remember. If in Europe we see "0thou" (2 or 3 cent, I don't remember) whit gauge on a placement or a tombstone, we arent really happy. This is a precisation, doesn't change my affect and my respect for what you and your team realize in your shop...

Lol I like your videos, but you're just wrong on this one.

I grew up with the imperal system and when I started machineing I found the metric system wins hands down. When the majority of the world changed to metric the reason America didn't was cost.

In 1997 I was lucky enough to be visiting guest at many high end institutions in USA. Metric vs Bananas was a topic than, confirmed by GM, CHRYSLER and BOEING that they have most of their work an design done in METRIC, except in the fields where there is a long and deep history behind. As at the time director of NIST said: you are only inches from going metric. 😅 So - you can run, fight or whatever - you have only a few inches left to be converted 👍

In fact, the only real reason to stick with the imperial system is the cost of conversion. But I think it will be worth it. Just thinking about the students who have to convert feet to inches ...

I'm a machinist too, and I use metric. the advantage of that is that you have less decimals to deal with when you have to use math. Most of the world uses metric, so in an international market it pays to use metric since almost everyone uses it. whether you grew up with metric or imperial, it is easier to visualize size, length etc. with the system that you grew up with, or use the most. they are just different systems of measurement, they are equally accurate. just because it's harder for you to visualize with metric doesn't mean imperial is better than metric. it just means you're used to it and haven't used metric enough to visualize it as easily. I see your point about cost to change the measurement system. it would not be practical to change everything at once in the way you describe it in the video. But you don't need to change old drawings and other things to change the measurement system, you can just start using metric on new drawings and products and over time filter out old design, which will at some point be updated or replaced anyway. Also putting more emphasis on the metric system in education and school would also have been a good idea, but I have got the impression that Americans do not want to change the measurement system anyway.🤷‍♀

I sold cutting tools to various machine and mold shops in my area. I got a call from a mold shop that did rubber mold for General Motors. All dimensions had been converted to metric. There was a tap callout that had every engineer confused and they called me to help. The tapped hole was listed as 12.7mm-13. After I stopped laughing I told them that it was an Imperial 1/2-13 tapped hole.

Ah yes teacup.. Which can vary in size and shape... 😂

I find it interesting that the machine manufacturers that are shown in the credits were mostly (if not all) developed and produced in metric and also work in this unit of measurement, the electronics may convert internally to imperial (this should definitely be the case with Trumpf, Blaser and Tornos).

“Imperial is superior, because America is superior” lol what a typical USA argument point 🤦‍♂️ This is the dumbest video from Titans to date, or they’re trolling 😆

changing to metric isn't a case of overnight everything must be changed to metric. It'd mean everything new should be done in metric. This results in about a 20yr transition period as older imperial systems are replaced with newer metric based ones.

Enjoyed another great Barry video even if I did not agree with all the points made. First as a mechanic, then as a corporate business person responsible for over 100 countries, and finally a machinist and machine tool build I long ago resigned myself to owning metric and imperial tools and being able to "think" in both systems.

As some kind of a machinist (~25 years around) I wonder if you have forgotten DIN (Deutche Industri Norme) that is quite important worldwide... I don't necessarily agree with the "we brought light to the world" though you have made nice things. I was looking at a Starret "Tap and Drill chart" and wondered about how difficult one can make a simple thing. M10x1,5 → 10-1,5=8,5 → drillsize 8.5mm. M10 on a rod: take a ∅10 rod, take a die and make a thread. No matter if it is M10X1 or M10X1,5 or something in between. I know there is a thread that is allmost the same (⅜ something?) but I have no idea on how to find it in a chart like that. And the drillsize is 0.XXXX but the drill is named something completely else. When I make parts in the lathe I often have to get them into +/-0.01 mm (hole +, "bar" -). Even if I would put one digit more, +/-0.001" is still +/-0.0254 mm so +/-0.0005" is getting close with +/-0.0127 mm. For me ∅60 mm is much easier to comprehend than ∅2.3622(047244)", or is that 2 13/98" or something 🤭😋... Like with volume/mass: water 1 dm³→1 l →1 kg→1000 grams. I truely tried to make a similar "path" in imperial (using Wikipedia "Imperial Units") but didn't succeed. I admit that I am defeated 🤯😱😉.

I have never heard a more american argument. Just leave it at, ya'll like it and keep it there. The superiority of stacking feet compared to standardized measurements, only makes sense for ppl educated in a third world country.

ok the intro was already bad. Because Nasa uses Metric XD so that statement is already invalid 3:16 and 80% of that stuff was actually invented in Europe. Why the fuck am i even still watching

I'd love to see an example where the number of factors of 12 (2 and 3 - 4 and 6 are just multiples) compared to those of 10 (2 and 5) gives a practical advantage.

I give you the point that graphic images can be more comprehensible in day-to-day activities. I grew up in Germany and breathed the metric system since my earliest childhood, but when it comes to cooking we use spoons and cups as measurement units, since adding a teaspoon full of salt to the meal is much easier than weighting out 4gramms. But this works only because spoons come in standard sizes, while feet on the other hand are a very individual thing and different for every person. In Europe we use a large step or lunge to visualize the lenght of a meter. When I was a kid we took 11 long steps to figure out where the penalty spot was when we played soccer. So I guess there's absolutely no difference between Americans and Europeans when it comes to build an intuitive feeling for their measument system. When someone says he's 1,85m tall I think of him as almost two lunges.

That whole argument is based on familiarity I’m quite sure you can make a metric cut using imperial measurement if you have highly precise equipment. As a person who has learned both systems if I needed to measure an imperial part and only had metric measuring tools I’d measure it and use that measurement and don’t convert at all just use the measurement I took with the equipment I had.

I’m familiar with both. Both definitely have there pros and cons as you mentioned. The only I do have a problem with is cups. Now that is not a measuring size

Statement that imperial system is more intuitive or makes more sense in day to day tasks really only apply if you've been raised by the imperial system. Same way people that have been raised by metric system can pretty easily proximate a meter or kg or what temperature would be in °C

My favourite part about the metric system is how all the measurements interact. One cubic centimeter of water weighs one gram and is one milliliter. It's frankly brilliant.

There is no way one could call them self a good machinist and not be able to use either

So basically it comes down to "it's a real hassle to change" and "I know how big foot is"? Very convincing stuff..

"and those who have landed on the moon". NASA uses the metric system!

Wow Barry, you poked that hornet's nest with a 2 meter pole!

The Pyramids of Giza are bullt off the METRIC . . . name ONE structure that's superior to that.. I thought so, haha'

I've worked with both systems everyday since day one, so I have an unbiased opinion. imperial is ok maybe if you are building houses, but precision machinists use metric. and that's how I've always seen it, but at the end of the day use whatever you are comfortable with. boom!

An Aussie here... Worked in an Aussie hydraulic manufacturing shop for 20 years with imperial drawings.. Leant on imperial 1970's G-code Fanuc Mazak CNC machines.. Now program Siemens and Mazak metric CNC machines everyday.. METRIC any day of the week!

NASA used metric to land on the moon XD no shaming though

Imperial units fucking sucks! Can't use for shit dividing by 16 ;)

I'm Canadian that works in machining in the oil industry, and we use the Imperial System like 85% of the time. We can convert to and from both pretty easily.

All units are arbitrary anyways. As long as the idea of "this part must precisely fit with other associated parts" is sufficiently conveyed, that's all that matters.

You know that you don't have to use metric measurements for everything right? When we cook, we use spoons and cups as well as grams and milliliters. That and the fact that NASA uses the metric system 😄

International system measure is metric. Imperial is just to be different than others. It's like driving on left or right side.

My very basic level idea is, that the 1 inch is 25,4 times longer, then 1 mm. That means, we can use one less digit after the decimal point for roughly the same level of precision for the maufacturing tolerances what we are working with..

I've started working with imperial and after 10 we had to change to metric because wed join the EU and it's the new standard, so we had to change to metric in the it was difficult but after a while I realized it's a simple system and easier use.
