American Wire Gauge (AWG) to mm and mm square

American Wire Gauge (AWG) is a U.S. standard of the sizes of the wire conductors. The Gauge is related to the diameter of the wire.

AWG is being used since 1857 in North America for the diameters of round, solid, nonferrous, electrically conducting wire. The cross-sectional area of each gauge is an important factor for determining its current-carrying capacity.
