There are actually reasons to use imperial, but it's all inertia. Industry has a bunch of controls and correlations and empirical equations that use imperial, so the inputs all need to be imperial too.

Of course, you could always do it in metric and then convert at the end. That's one approach to unit systems.

if you're going to use Javascript ~~to build an enterprise level software~~ you are guaranteed to have a bad time

ftfy. also applies to Python for any code you plan to use for more than 1 day

I like to measure the area of rooms in foot-metres. Square foot-metres is a great unit for volume.

Today I unironically described the length of something as "about 1 centimetre less than a foot".

And I just understood why that’s the case. Most of the old units used highly composite numbers as factors, which have an incredibly high number of divisors. We still widely use such factors for time and angles.
