minus-squarederphurr@lemmy.worldlinkfedilinkarrow-up1·10 months agoThere’s no non metric electrical units except ohms/1000 ft or cross section dimensions, and AWG (and MCM kilo circular mils kcmils) versus mm^2 Why US uses awg with reverse scale instead of diameter is insane formula: D(AWG) = 0.005·92^((36-AWG)/39) inch
