What is MCM size?
MCM is an abbreviation for thousands of circular mils, an old measurement of wire gauge. 1 MCM = 1 kcmil = 0.5067 square milimeters. A mil is 1/1000 inch. A wire 200 mils in diameter is 40 MCM.

The other caveat is the above table is based on stranded cable (the vast majority of cables are made up of stranded conductors)….A Simple Guide on Cable AWG to Metric Conversions.
| Metric MM2 (Diameter) | AWG | Approx Strading |
|---|---|---|
| 1mm | 18 awg | 32/0.2 |
| 1.5mm | 16 awg | 30/0.25 |
| 2.5mm | 14 awg | 50/0.25 |
| 4mm | 12 awg | 56/0.3 |
What is the difference between MCM and kcmil?
One mil is equal to 1/1000 of an inch, and one circular mil is the area of a circle that has a diameter of one mil. The reason MCM and kcmil both mean 1,000 circular mils, is that the letter M in roman numerals is equal to 1,000, so MCM is 1000CM, or 1,000 circular mils.
