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 mm² to AWG
AWG is a geometric series: diameter (mm) = 0.127 × 92^((36 − AWG) ÷ 39), and the area follows from the diameter.
Example: 12 mm² = 6.44414 AWG.
