@tkalvas @becomethewaifu @tilton The civilised world uses mm² for wire cross section, from appliance flex through to high voltage power lines. The US uses AWG for little stuff and "kcmil" for the big stuff. A "kcmil" is the area equivalent to one thousand wires a thousandth of an inch in diameter (kilo circular mils). Also called MCM because some people prefer roman numbers. Is there a more horrid unit?
