In practice you would just use decimal inches. Doesn’t really make it better but you can machine something without ever seeing a fraction if you want to since everything will be in thousandths of an inch.
most electronics breadboards and the pins from (non-tiny) microchips / ICs are spaced at 2.54mm apart, which i eventually realised is a tenth of an inch.
Maybe in your particular industry, but I reckon most people using imperial units aren’t using measuring devices with decimal inches or needing the precision of .0001"

Decimal inches?

hey none of that mathematics witchery here dude. we guesstimate or we do nothing (and i’m too tired to guess)
