Thanks, you made it easy, I was riding my bicycle a couple months ago & found a tape measure like this on the sidewalk & was trying to figure out how to read it.

Thank you I been doing construction for years on inch measuring tape switching to engineers is confusing but thanks for helping with this video it’s a good reminder now time for calculating

Interestingly… owning and understanding the how’d and when’s and what’s of these common currencies within your own culture and region… applies to other same but different stories of other cultures… diversity of contexts and languages over time. The intersection points of those contexts help better understand local eco systems and larger interactions in fluid miners and within time and space. I need to take algebra again…. It’s so cool.

If we consider Values in complex terms and the insights in which they are supported… the positive feedback loops are not just “nice” it helps ease bias and conversations. The old phrase about drawing swamps and ap to your ass in alligators… the North Star thinking helps keep the tacking on better tracking. The actual insights get nuanced. Any, KPI can lead to end points… the better insights and connections help a lot

You do a great job on these videos, friend. I very much enjoy watching them. If I could add a little criticism, I would suggest for filming and instructional purposes, that you keep the tails of your 9s straight so they do not look like lower case Gs, which might confuse some. Thanks for the videos, mate.

Do you have a video on how to measure a tape measure that has 32 marks for every inch? or do they not do this any more? most tape measures now seem to be only 16ths now, did they convert to 16th even here in the UK?, the 32 marks ones measure out a little differently, a few measurements are in different places but i cannot find any where that can explain to me how to read inches with 32 marks.

FlyingMonkies325 They are around, being used by machinists, cabinetmakers, etc. just hard to read (vision-wise, not maths) and are not for rough work (carpentry). Also Tesco does not carry any of the instruments featured in the following videos. So I have one in 64ths: kzfaq.info/get/bejne/n7xopZZ4s5u9kZs.html and another in 64ths and 128ths, from it the 32nds will be easy (math-wise), though visually different as they are not "black-on-yellow", like most measuring tapes. kzfaq.info/get/bejne/icWqpqiBrrSVdX0.html There are plain rulers in 50th and 100ths of an inch, too. Once you get them, 32nds will need very little figuring out. kzfaq.info/get/bejne/ZtFol9mVmc6aZIU.html I also have dial indicators in the 1000ths kzfaq.info/get/bejne/itiClqiYlbSmaXU.html and micrometers in 10,000ths kzfaq.info/get/bejne/bJ2Zo6SEzJuWdHk.html

@FlyingMonkies325 9 жыл бұрын

Thanks :) i think i will stick to the imperial tape measure as i'm only using it for paper so i think that's why rulers have imperial measurements too (16ths measurements), i'm planning to make my own laminated ruler with lined paper because with some things it's easier to read than my see through blue fold-up one, imperial is just so much easier to read because you have a bigger side, math has never been my strong suit but it was worth a try trying to read my dads tape measure lol, oh well.... thank you for the help anyway.

FlyingMonkies325 No worries. All of the fractions mentioned before are imperial measurements. I`ll shoot a video tomorrow on those 32nds. Others probably need it too, we just don`t hear from them. It`ll be just a few minutes, I`ll keep you posted.

Rod K Think legal surveryors. Instruments. Laser. Optics. Pro tripods. You find this measuring tape in a surveyors` supply store, along with waterproof notepads & markers, hi-viz tapes, etc. This tape has decimal FEET. If you need decimal INCHES, such as kzfaq.info/get/bejne/ZtFol9mVmc6aZIU.html, get them from a machinists` supply store. Inch/feet-based AND mm 2-in-1 tapes are sold in countries where both systems are around, Canada for sure, maybe elsewhere too but Stanley or any brand such tapes are mostly made in China, so can be sourced out from them at the point of manufacturing too.

@ⒸⓗⓐⓇⓛⓘⒺ, Because that was the part of my education when I was back in Elementary School since the year 2001. Sorry Charlie and too bad if you disagree or dislike this video because this is 100% acutely the correct measurement though out the whole world. Metric System came first and it was original before the English Standard System. Don’t be a wannabe because I got god and Jesus with me. It’s a true fact and if you are rude and disrespectful then you get the bad karma and the negative consequences. Go look up your favorite subject if you are not interested in this math topic such as counting money and bills. Don’t argue with me because this is our business or else test grade F- = 40 to 59% correct and 41 to 60% incorrect for you. I watched your videos and you just named yourself after a pet male dog named Charlie like all dogs go to heaven. You live in the State of Georgia, you own a rifle as your firearm and film disturbing images of deceased animals and do drugs. You opened a can of beer or soda with a knife, and filmed a trash can, urinated in your own household bedroom, your toilet has a scratched toilet cover seat with nails and pins all over it and you were running like a maniac after being tardy and got late to work and not arrive on time to your job place. By the way, you only got a very few likes on your videos and mostly dislikes.

Leave me alone and please stop because I don’t even know you.

Interesting! I've never heard of someone who grew up learning decimal feet rather than the usual feet + inches + halving-based fractions of an inch version of the customary or imperial systems. Where did you grow up to learn metric in kindergarten, and who was teaching you decimal feet-the school or your parents?

@Persun_McPersonson Жыл бұрын

@@eugeneyang5678 I'm not sure Charlie was asking with malicous intent, but either way Charlie would not have inherently gotten any negative consequences from being potentially disrespectful in this conversation because karma, God, and Jesus are not "true facts," they are in no way scientific explanations for the world and belong with the old English units rather than the more-logical metric system. Also, you shouldn't let a random stranger on the internet just curiously asking "Why?'" to get you so riled up to where you dig into their profile so you can make an entire paragraph insulting them. If Charlie was indeed being rude, then you have actually been _extra_ rude, as he in no way went so far as you did to be disrespectful. So my point is that you're being a bit of a hypocrite.

@astig7135 4 жыл бұрын

how do you read 1/4 of an inch in there then?

@eugeneyang5678 3 жыл бұрын

@La-di Da-di, 1/4 of an inch would be 0.25” in U.S.A. Tape Measure & 1/4” on this tape measure out of a foot would be 0.0208333 feet long (0.0208333’ = 1/48’) 1/48 feet long is 1/4 of an inch on this 10th decimal feet tape measure. It is so short and tiny that you will have to line it up with another foot ruler to actually get it right on the mark. I recommend using a metallic lead pencil instead of a wooden #1 or #2 pencil that is dandelion yellow with a pink eraser on top that U.S.A. Makes to write it very neatly and colored pens like he used on this video may be permanently unerasable.

apprenticemath I know the problem, even in Europe we have to cope with some materials with Angelsaxon measures. But it is never a problem for me: take your own measures with metric equipment and dont bother with the sometimes quaint numbers as for instance the 2,45 mm pitch of an IC footprint.

@apprenticemath 9 жыл бұрын

Roeland Voogd Totally works. This decimal foot scale on this tape is widely used by surveryors in North America. It`s not relevant anywhere else. The numbers are not making sense to any trades, site layout by carpenters is done in feet-inches (on an inch-based project). Decimal feet are used in calculations, say how much does glass cost if a 62-inch by 43-inch piece is needed, $8 per square foot. 62 inch = 5.1666 feet, 3.583333 feet, after multiplication = 18.5 sq.ft. x $8 = $148.11 It`s practically medieval, when the workers showing up for any new cathedral project were given a length standard, say Hessian foot, and everybody copied that scale and worked with it on that site only. As a result, columns, beams, arches, doors are not interchangeable from one cathedral to another, they are all different even if they look identical architecturally.
