I just got a haircut, here in the US they commonly use some unclear numbering system. They said to me “Do you like it at a 4? We could start there and go to a 3”
I looked it up and apparently they’re 1/8ths of an inch so there’s at least some sense to it.
I assume they’re asking what length of blade guard to use, as sometimes they do come in mm sizes
always IME. What else could it be?

Could be fractional inches, but I’ve never seen it; arbitrary numbering is pretty common on cheap razors though
I can confirm that’s the case where I live.
