I think that mil is short for milli inch, which is really mixing systems. I think that power folks do even worse. Wires larger than 4/0 are given in circular mils, or cm. When I started with a power company 42 years ago, one thousand circular mils was MCM, where the M was from Roman Numerals for thousand. That was confusing, as it could also refer to Mega, so the M was changed to K for Kilo, so we had Kcmils.
