Definitions: Mil: 1/1000 of an inch Circular Mil: The area of a circle 1/1000 inch in diameter MCM: Thousands of Circular Mils kcmil: Thousands of Circular Mils (same as MCM) AWG: -4.3125 LN (mm2) + 17.16 (approx interpolated) –or- AWG: -4.3125 LN (inch2) - 10.74 (approx interpolated) Aught: An old English contraction of "one naught" meaning "one zero". Logical AWG numbers are developed by continuing the series in a logarithmic relationship to the cross sectional area of the wire.
