AWG - American Wire Gauge vs. Circular Mils (original) (raw)

AWG vs. diameter mil, circular mil, diameter in mm and area in mm2.

American Wire Gauge (AWG) is a U.S. standard for wire conductor size. The "gauge" is related to the diameter of the wire.

The AWG standard includes copper, aluminum and other wire materials. Typical household copper wiring is AWG number 12 or 14. Telephone wire is usually 22, 24, or 26. The higher the gauge number, the smaller the diameter and the thinner the wire.

The Circular Mil - CM - is a unit of area used especially to denote cross-sectional size of a wire or cable.
