MCM means 1000's (M) of (C)ircular (M)ils
kcmil means 1000's (K) of (C)ircular (M)ils
Mil means 1/1000 inch
Circular Mil means the area of a circle 1/1000 inch in diameter
AWG = -4.3125 LN (mm2) + 17.16 (approx interpolated)
AWG = -4.3125 LN (inch2) - 10.74 (approx interpolated)
Logical AWG numbers are based on continuing the series in a logarithmic relationship to the cross sectional area of the wire.
