Also, can't you guys from USA just... use mm? :^P Seems sound from a "scientific" standpoint, but... this is a little bit like wiring and pipes.

If you say something needs "X.XXX millimeter thick" wiring, you're going to have a hard time sourcing that, because wiring is sold by "gauge", not metric thickness (AND it's on a bass-ackwards upside-down scale; 20ga wire is thinner than 18ga wire!).

Tubing and PVC pipe is still mostly manufactured in even Imperial fractions, too, seems like.

Craft foam is sold in 12"x18" sheets, for example, and the thicknesses used to be 3/16", 3/32", etc (if I recall correctly, haven't bought any in a decade)... but that might not be true anymore, after checking Michaels' and HobbyLobby's websites...

(No objection to "converting" all the measurements to metric and including BOTH on Wiki pages.  It's not like these values change all the time and require dual maintenance, LOL)
