      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.

      Could be fractional inches, but I’ve never seen it; arbitrary numbering is pretty common on cheap razors though
