For that cm is used. [This](https://dostawaokien.pl/en/blog/door-sizes) is how the standards seems to look.
> Standard sizes. Most often, these are doors with a width of 80-90 cm and a height of 200-210 cm.
Wow, sure that must have been crazy, right? And if you think "2 by 6 foot" is accurate enough - for customers it's the rough cm value, for practitioners it's mm-precision. Even that 2 by 6 foot will have some standardized calculation to have precision.
And we know our body height, so 210cm vs ~180cm means 30cm is free above your head. No inches and feet and elbows necessary.
*Although customary units are used more often than metric units in the U.S., the SI system is used extensively in some fields such as science, medicine, electronics, the military, automobile production and repair, and international affairs.*
So you are the kike who has no idea how things are built.

The UK is a useless comparison, because everything was built before metric was phased in. Of course they still use feet and inches.
Just that 3" by 4" is now called 75mm x 100mm nominal
