They are both abbreviations for the same thing. Both MCM and kcmil abbreviate a unit called ‘thousand of circular mils
Circular mil
A circular mil is a unit of area, equal to the area of a circle with a diameter of one mil (one thousandth of an inch). It corresponds to 5.067×10 mm². It is a unit intended for referring to the area of a wire with a circular cross section.
What does kcmil stand for in electrical?
KCMil – A method of measuring conductor size that stands for thousand circular mils. K represents kilo for 1,000. C represents circular, and mil, M, is 1/1000 of an inch.
