When I worked in the lumber yard,we had a high-school Deca student girl,that was in danger of flanking out of math class because she didn't understand fractions; I got her a tape measure & we went to the warehouse where the dimensional lumber and plywood was kept; for several days my boss allowed me to help her with " lumber yard" fractions- basically the exact same method you used in the video! On the day of her math test,she came to work with a smile on her face & a copy of the test with an A- minus on it! She said the teacher told them they couldn't use calculators or cell phones in his class...but he didn't mention anything about a tape measure;( the math teacher knew she was a D.E.C.A. student & worked that class at our lumber yard & didn't think anything out of the ordinary when she came to class with her company issued tape measure) she told me later ,when she had a hard set of fractions to add or subtract,she pulled her tape measure out a couple of inches & figured out the answer! I wish more teachers & young people could learn " lumber yard fractions" Back in 1965 when I was in the 1st grade,we learned " math" on wooden ruler with a metal straight edge. Just before our D.E.C.A. student graduated from high-school, we had one of our regular yard hands call in sick & we had a large order for some custom cut lumber...our student volunteered to go out in the yard & help get the order cut to specifications! It made me proud when the order went out on time & no mistakes made in the custom cut lumber! Sometimes the old ways are still the best way!

Dad growing up during the depression started working early and made sure us kids did too. I was 6 the summer between 1st and 2nd grade when he was putting 1xs on a roof on an addition to our house when he first had me cutting boards for sheathing with a circular saw. I'm sure he would have get in trouble for that now days but I've been sawing ever since and still have all my fingers so ....

Old carpenters know lots of neat tricks, especially with folding rules and angle squares. As an Instrument Fitter, I was taught to write everything down in base 16 so 5 7/16" is written as 5.7. If I needed greater resolution for say 1/4"OD tubing and below, I would add a 32nd by putting a + sign behind so 5 15/32" is 5.7+. The whole process that we were taught of simplifying fractions just wastes time. Of course, just going metric is also a nice idea if you can but wasn't practical when using materials sized to imperial dimension.

Here's another trick to add to your tool bag: Easy way to divide odd fractional measurement in half (find midpoint): Say you want to find half of 17 3/8" Reduce the 17 to the next lower whole inch and divide by 2 (16/2 = 8) Add the top and bottom of the fraction (3+8 = 11) Put that sum over the next smaller fraction (11/16) Midpoint of 17 3/8" = 8 11/16" Do it a few times on paper, and it will become very easy to do it in your head.

You really should stress that this only works if the number of whole inches is odd, and that it gives the wrong answer if you try it with an even number of whole inches. I know you wrote it was for odd numbers, but I think it could be easaily overlooked. Pretty nifty trick though.
@brettchr777 Жыл бұрын
Clarification: In the above method, "odd" is not a synonym for "unusual." It is +mathematical+ odd. The method fails if the whole number is an EVEN number. Example: Half of 6 3/4 is not 3 7/8. It'll always work when the whole number is ODD: Half of 7 3/4 is 3 7/8.

Its so much easier to use metric. When I first started working I was given the task of adding up all the dimensions on the plan of a large slab sided office block that was in a long string of imperial measurements of feet, inches and various dissimilar fractions, as the guys on site had set out the two sides and they were different lengths. I spent all day doing the arithmetic and couldn't get them to match or even get consistently close, eventually I got a close consensus and passed it on to someone else to resolve. Had it been dimensioned in metric it would have taken me 5 minutes with a calculator or ten minutes by hand.

@@nilpo yes and no. Sure, you *can* use fractions in the metric system, but typically, you do not. If you need more precision than millimetres, you use micrometres, but you've then entered the realm of engineering, not carpentry. Similarly, you can go from micrometres to nanometres. And yes, there are further, higher precision scales* if you really need them, but then you're well beyond engineering and in the world of particle physics. * They're really not separate scales, the prefixes represent specific powers of ten: pico (10^-12), femto (10^-15), atto (10^-18), zepto (10^-21 ), yocto(10^-24). For example, the diameter of a Hydrogen atom is believed to be around 212 picometres (2.12*10^-14 metres) in diameter. What fraction of an inch is that?
@nilpo Жыл бұрын
@@mattlivingston2192 Oh, I understand how it works. For scientific measurements, sure, metric is fine for defining precision. But measuring in everyday life is more often qualitative, not quantitative. I know they two halves fit in a single inch. If something is 3/8 inches, I know without any thought that I can fit at least three 1/8 inch objects in that space. I wouldn't use inches to measure the diameter of a hydrogen atom to exacting standards. Take cooking though. If recipe calls for 2/3 cups of flour. It becomes almost thoughtless to half the recipe. And that recipe doesn't require the exactness of micrograms. It's also easier to use smaller measurements collectively. If my recipe instead called for 3/4 cups flour, but I only had a 1/4 cup measure. I know without any effort that I need to use my measure cup exactly three times. These applications, while possible, are far less intuitive in the metric system.

Now my father had been a carpenter since he was a kid during the depression, and had no formal education. He could barely write his name, yet it was obvious to me that he was working some kind of math using that ruler.

The difficulty here is not metric vs. imperial, it's fractions vs. decimal. However, the imperial inch is not a great carpentry unit when using decimals, because 0.1" is too crude and 0.01" is too fine. On the other hand, 1 mm is plenty fine enough unless you are doing really intricate woodwork, yet it's not so fine that it's difficult to line up a pencil mark. For that reason, I find metric easier for carpentry. In the case of machining, imperial measurements are always expressed in decimal inches, so you don't run into this problem.

Nice. I had the answer in my head within a few seconds. I'm old, so I learned fractions of inches in my younger days. These days everything is metric where I am, so that's what I use now. I like maths tricks. I'm going to show this one to my son.

I think you should teach your son how to do proper maths instead; especially given that inch fractions are so simple as they're based on multiples of 2...

so next you can tell us what the diamond is for on the tape at 19.2 and 38.4, 57.6 etc? It's for framing and saving 1 stud every 8 feet I think.

I do understand what you are doing , but your last scenario could confuse someone or have them make a wrong cut . If I were showing someone how to do that scenario I would have put the end of my measuring tape on the 12 7/16 mark and measure out the addition of the 5 3/8 to come up with the total . Your way showed the correct measurement , but not for cutting the piece shown . I do understand your process though and thank you for the time and effort that went into making this video .

Nice! I can add fractions in my head and I'll still go with this.

I do something similar. I measure and make a mark at the first number. Then I put the 10” mark on the tape measure on that first pencil mark and then measure the second distance and make another pencil mark. Then hook the tape and pull to the second mark for the total.

You'll need a longer board if you need to add 14' 5 3/16 + 9' 1 3/4" or 54' 4 2/8" + 132' 3 9/16"

With metric system you just add all the mm's and that's it.

Haha that's funny you should use the term old-time Carpenter. When I first started out some fifty years ago as a carpenter's helper, I used to refer to all the old guys as old-time Carpenters. Guess I'm one now. Thanks for the tip...

As someone who has been measuring and cutting for 50 years, I long ago memorized all 16th decimals, then add numerically.

Since you have the tape out, find 12-7/16, add the 3/8, then count up 5. No need to remeasure or “bury” the second number
