What is that wire for?
Current figures are rough guidance only. Real ratings depend on insulation, bundling, ambient temperature and local wiring rules.
The math
How to convert mm to AWG
AWG is a geometric series: diameter (mm) = 0.127 × 92^((36 − AWG) ÷ 39), and the area follows from the diameter.
Example: 12 mm = -3.23017 AWG.
