American Wire Gauge
AWG
Brown and Sharpe Wire Gauge

   <hardware, standard> (AWG, sometimes "Brown and Sharpe Wire
   Gauge") A U.S. {standard} set of non-ferrous wire conductor
   sizes.  Typical household 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.
   Thicker wire is better for long distances due to its lower
   resistance per unit length.
