What it means
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 kcmil to mm²
AWG is a geometric series: diameter (mm) = 0.127 × 92^((36 − AWG) ÷ 39), and the area follows from the diameter.
Example: 12 kcmil = 6.08049 mm².
