**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?

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 (
