Equivalence between metric size and AWG-kcmil
The US American standardization extracts several standardized sections from 0.324 to 253 mm2. Sections are designed by a gauge-number AWG or a section in MCM (Mil Circular Mil). AWG numbers are identical with the British Brown and Sharpe (B&S) numbers.
1 Mil = 0.0254 mm = 1/100 inch
1 MCM = 0.5067 mm2
