MCM is an abbreviation for thousands of circular mils, an old measurement of wire gauge. 1 MCM = 1 kcmil = 0.5067 square milimeters. A wire 200 mils in diameter is 40 MCM. MCM is generally used for very large-diameter wire.
Besides, what is the circular mil area of 10 AWG?
AWG, diameter mil, circular mil, diameter in mm and area in mm 2

How big is a circular mil?
The circular mil is a unit of area used especially when denoting the cross-sectional size of a wire or cable. A circular mil is the equivalent area of a circle whose diameter is 0.001 (10-3) inch, or approximately 0.7854 millionths of a square inch. Mils of circular wire or cable can be calculated as:
mils = 1000 d (1)
What is the unit MCM?
Thousand circular mils or kcmil, the wire gauge is equivalent cross sectional area (500 MCM = 500,000 circular mils) Million cubic metre, the unit of volume.
