logical

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".

Mate, just use metres. It's way easier

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.
