WebThe Circular Mil. In the electrical industry, we use a unique unit to describe the area of a conductor – the circular mil (CM). Standardizing on the CM gives us a simple way to … WebA circular mil measured a cross-section of a wire. Circular mill is a very small unit – equal to 0.0005067 mm2 area – so we use ‘thousands’ of them in a unit like MCM or kcmil: kcmil standards for ‘kilo circular mils’. MCM stands for ‘thousands (M) of circular (C) mils (M)’.
