When I find a wood working video on YouTube from the states it blows my mind how anyone can not just adopt metric
“This is 5” 4/57 and we need to cut it to 5” 5/45 and a half” bzzzzzzz.
I may be biased, but I think it kinda makes sense. All the fractions are really just powers of two:
One half
One quarter
One eighth
One sixteenth
One thirtysecond
etc.
Oh yeah, totally makes more sense to say “it’s 3/64ths of an inch” than “it’s 2 millimeters.” Completely reasonable.
So reasonable, in fact, that in most manufacturing that still uses imperial measurements they long ago abandoned fractions and moved to decimal inches.
Which leads to unholy abominations such as the wood shop sending over “cut off 3/64ths” and the metal shop cutting off 0.046875".
And all of the fractions in metric are just powers of 10: one tenth, one hundredth, one thousand. Powers of two are great when you’re working in base 2. It’s a big hassle when you’re working in base 10.
Everyone also gravitates to length and how fractional powers of two are sensible. I’ll grant that they’re at least sensible although awkward in base 10. But what about every single other thing? For lengths greater than one inch, there’s no consistent pattern. For volumes there’s no pattern - mass, weight, etc. The thing is a monstrosity. People pick out one part that’s halfway acceptable and act like that’s a defense of the rest of the pile of garbage.

In case the metric folk want to write it down and work it out yourself:
7" 1/4 minus 6" 7/8 = 184mm minus 174mm
7" 1/4 minus 5" 5/8 = 184mm minus 142mm

Lmao metal shop guy here. Can confirm the bastardized decimal inch measurement system.
“What do you mean it was bent 0.0125” off at 112°?!?"
Man’s over here asking for hundred-thousandth inch precision
And I’ll give it to her all. minute. long.
Mate, just use metres. It’s way easier
Ain’t no freedom in meters!
Sure there is. Also equality and fraternity.
Daily reminder that imperial comes from the word ‘imperium’, which had nothing to do with the US of A.
