WHAT IS DIFFERENCE BETWEEN MCM AND KCM IN CABLES?

MCM (thousand circular mils) and KCM (kilo circular mils) are both units used to measure the cross-sectional area of electrical conductors. MCM is equivalent to one thousand circular mils, while KCM is equivalent to one thousand MCM, or one million circular mils. Essentially, KCM is a larger unit, used for measuring very large conductors, whereas MCM is more commonly used for medium-sized cables. The choice between them often depends on the size and application of the cable in electrical systems.
