In the US trades, every measurement is expressed in ft/in, with fractions by 1/2, 1/4, 1/8, 1/16, 1/32 as they’re expressed on a standard US tape measure. No one uses 5ths, 10ths, etc
eager_eagle@lemmy.world 7 months ago
frankly, using predetermined denominators only seems marginally better to me
it makes me wonder who decided that
32 3/8 inwas more readable than32.375 infhqwgads@possumpat.io 7 months ago
To be fair 10ths are a thing in surveying. And occasionally engineering I guess but I’ve never seen it.
I want a ruler in 3rds just to mess with people now though.

Except 1/100 and 1/1000 because consistency

When dealing with fractions of an inch, measuring devices ALWAYS use base 2 denominators (1/2 inches, 1/4 inches, 1/8 inches, 1/16 inches). They actually have ticks on the tape measure to represent those values. By convention, measurements are as well written down using that same principle.
It’s so ubiquitous, that people fall apart if it’s deviated from.
Also, from a practical perspective, there won’t be an explicit mark on a tape measure for any of those measurements, so they’d need to kinda fudge that if they wanted to take a more precise measurement with a standard tape measure.
In Canada at least, it’s pretty common for a tape measure to have metric and imperial units. Not sure if that’s the same on the US. In this situation, I’d just use the metric. And for any of the highlighted measurements, I don’t think I’d be to stressed out about if I mismeasured by a 16th of an inch anyways.

I’m in New Zealand, we exclusively use millimeters for work like this, and I’m so glad we do.
What a mess.

How would you then represent 1/3 inches?
ummthatguy@lemmy.world 7 months ago
The fractions don’t correlate to known measurement increments. It’s nonsense typed up by someone unfamiliar with appliance specifications.
Ilovethebomb@lemm.ee 7 months ago
I see. I’m not familiar with the Yeehaw measurement system, so I didn’t pick up on that.

Did you ever read the works of Shan Yu?

The mm are right there.
SatansMaggotyCumFart@lemmy.world 7 months ago
I like mm.
59.8mm sounds much better then telling someone to suck both of my inches.
Denalduh@lemmy.world 7 months ago
I received a drawing a few months ago that had the following dimensions called out: 1/8", 2/8", 3/8", and 1/2".

I mean, 1 4/5" an inch is pretty close to 45mm…
ccunning@lemmy.world 7 months ago
I think they’re trying to convince you to switch to metric.
marcos@lemmy.world 7 months ago
But the imperial system is so convenient, you just use fractions instead of decimals…
/s, because well, this is the internet.
bobs_monkey@lemm.ee 7 months ago
The measurements in parentheses are millimeters (or close enough), so it looks like a shitty conversion from a non-US manufacturer that doesn’t use imperial
wjrii@lemmy.world 7 months ago
Yeah, I reckon somebody told the drafter Americans use inches and fractions and they did not clarify any more than that.
Our system is antiquated and kind of unwieldy, but it is a system. Power of two denominators for most things, decimal inches for surveyors and machinists.

916mm is 36" 1/16, so it could very well be 916mm converted to imperial and rounded off.
