I did not mean imperial dimensions as such, but threaded parts, their
multiple standards, varieties, and markings.
I can more-or less easily convert or imagine stuff in imperial units
now, since I am reading a lot of technical texts written by Americans.
But for threads it's completely different story. There is standard row
of diameter/pitch, for all the other cases pitch is written in a
blueprint.
