Used for engineering units I think. Someone correct me if I’m wrong. Working for my dad who is a land surveyor, we took measurements in tenths which is then translated onto the maps and drawings.

edit* our tape measures and rulers were marked at every tenth of an inch so we would read the measurement out loud as 1.4 feet

They’re awesome and once you get used to it, 8ths never makes sense again.

MaroonGoon, you are correct. You may also find them in the machinist trade, but mostly in the surveying trade.

Rick, kinda like mixing metric and SAE!

Cheers!

I often saw used measuring tools graduated in 10ths and 50ths that once were used in the Pratt and Whitney aircraft engine factory.

Starrett still sells then new.

They are used in the drafting of engineering drawings….in the pencil and paper days. They are great and make a lot of sense when you are converting everything to decimal fractions.

A dial caliper is graduated in 10ths.

I use both imperial and metric calipers a lot.

Engineers scale, they are great because everything is automatically in decimals and eliminates fractions. Unfortunately no one uses them and therefore all plans and lumber sizes etc are all geared to fractions of an inch instead of tenths of an inch.

I have a rule in tenths at my desk and it gets used in this way: Scaling dimensions off a picture. Sometimes a few dimensions may be given. Sometimes you can infer a dimension, say the height of a table or desk. From that you can get all the other dimensions you want using ratios. If I had to do it in fractions, it would take nearly as long as doing it in roman numerals.

Kindly,

Lee

sounds like some one wants to use the metric system … lol Metric would be good if it had an inch. decimeter is too big and centimeter too small ;-(

Decimal fractions are so much easier to woirk with. I was on a job a few years back. the welder showed up to do some measuring for his part. We were making a grooming room for a vet. There were to be 6 kennels on each side and he wanted to make sure of what he was building so it would fit the space. Unfortunately he had left his calculator that works fractions. I told him to give me the dimensions he was getting on his tape measure. He read them off and I wrote them on a board in decimals and added them up. I did my division or whatever we needed. He didn’t trust me but he left with my board and it WAS correct. Decimals are really easy to work and the scale is callibrated for reading them.

Actually most tapes have decimals, but .125, .0625, ect aren’t quite as convenient as .1,, .2, ect. But it will keep you mentally sharp(er) ;-))

That is what I do most of the time Topa. I convert all the 1/16th’s to decimals to work with them. I memorized them 35 years ago by using them. part of my job.

You will be sharper if you forget them and recalculate every time you need one ! ;-))

I cn calculate them but since I know I just jot it down. I add , subtract or whatever and then covert them back to common fractions. They have to convert if you have used 1/16th’s or 1/32nd’s. I know all the decimal fractions to an inch. Just learned thm over the course of a short time back there. I used them daily and remembered them. Hard to forget them. If I do forget them I might not be sharp enough to do the math anymore….LOL
