Interesting flex. Apollo Guidance Computer was working with Metric SI units internally.
Calculations were carried out using the metric system, but display readouts were in units of feet, feet per second, and nautical miles – units that the Apollo astronauts were accustomed to.
But then you’ve got a space that’s 5’ 7 3/8" and you need a clearance of 7/32" on each end, so your piece should be…uh… 5’ 6 15/16" long. So much easier than metric, right?
In metric it would be 1711mm (or 1.711m) and you’d need to take 5.5mm off each end, so it’s 1700mm. (For the record, I picked random numbers in imperial and only did the metric conversion afterwards, I just lucked into the nice round number here.)
I dunno. You need how many sig figs you need in whichever system, but switching between a factor of 12 for the feet, base 10 for the inches, and the equivalent of binary decimals for the partial inches sure does take getting used to. I’ve finally gotten used to it enough that I can do it in my head, but I prefer to work on metric for most things.
I acknowledge that machinists just use thousandths of an inch, which does greatly improve working with that system, but it also introduces a third kind of measurement that can’t easily be interconverted with the other two. I dunno. It just feels like we’re doing way too much work propping up this archaic system when literally everyone else in the world is using something simpler and we could just be on the same system.
Feet, yards, inches should be replaced by the metric system.
There are 2 types of countries in this world: 1. Those that use the metric system and 2. Those that put a man on the moon ;)
Funny thing is, NASA uses metric.

When you can divide a meter evenly by 2, 3, 4, 6 we will talk. Until then take your crappy base 10 measurements and stefu!
It can be done just like for feet and inches, look:
Yet I only need an integer when using the imperial system, and I don’t have to repeat 3 into infinity.

⅓m is 1.093504 feet or 13.12205 inch. I don’t see how it’s more convenient.
Work in a machine shop for a week and get back to us
The entire planet’s machine shops do fine.
1x1x1 metre cube holds 1000L of water, and weighs 1000kg.
Uh? Done. What happens now?
What machines do u run in what country?
What does it matter? I could say any one of the +190 countries and the answer would be more or less the same.
