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?
· The terms MCM and kcmil are used interchangeably by the National Electric Code to describe wires that are larger than 0000 American wire gauge. 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 …

Glossary Term: kcmil 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.
What does kcmil mean?
· Glossary Term: kcmil 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.
What size is 250 MCM?
MCM is the old word for indicating the size, while kcmil is the newer word for indicating the same thing. What is the meaning of Kcmil, on the other hand? MCM is an abbreviation for thousands of circular mills, an old wire gauge measurement. Glossary Term: 0.5067 square meters = 1 MCM = 1 kcmil. A mil is a millimeter in diameter.
Is 250 mcm the same as 250 Kcmil?
For example, one common wire size used in the NEC has a cross-section of 250,000 circular mils, written as 250 kcmil or 250 MCM, which is the first size larger than 0000 AWG used within the NEC. 1000 circular mil equals 0.5067 mm2, so for many purposes, a ratio of 2 MCM ≈ 1 mm2 can be used with negligible (1.3%) error.
What's another term for Kcmil?
One million circular mils is the area of a rod with 1000 mil = 1 inch diameter. MCM—one thousand circular mils. This is an older name for kcmil and is an identical unit. It is still in widespread use in the United States.
What is Kcmil wire?
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. A wire that is one mil in diameter has an area of one circular mil or 1 KCMil. KCMil replaced MCM for sizing conductors.
Is MCM and AWG the same?
