AWG to square millimeters
Type a value in AWG to get it in mm² instantly.
That's 1.32× as thick as socket circuit cable, while cooker cable is 1.81× thicker. Roughly 19.85 A in free air, depending on insulation and installation.

Current figures are rough guidance only. Real ratings depend on insulation, bundling, ambient temperature and local wiring rules.
The math
How to convert AWG to mm²
AWG is a geometric series: diameter (mm) = 0.127 × 92^((36 − AWG) ÷ 39), and the area follows from the diameter.
Example: 12 AWG = 3.30877 mm².
