AWG is sometimes also known as Brown and Sharpe (B&S) Wire Gauge. The n gauge wire diameter d n in inches (in) is equal to 0.005in times 92 raised to the power of 36 minus gauge number n, divided by 39:. Wire gauge refers the physical size of the wire, rated with a numerical designation that runs opposite to the diameter of the conductors—in other words, the smaller the wire gauge number, the larger the wire diameter. When choosing wire gauge, the distance the wire must run and the amperage it will be expected to carry must be determined first. American Wire Gauge Conductor Size Table.

The larger the AWG number or wire guage, the smaller the physical size of the wire. The general rule of thumb is for every 6 gauge decrease the wire diameter doubles and every 3 gauge decrease doubles the cross sectional area. Diameter Notes: A mil is a unit of length equal to 0.001 inch (a "milli-inch" or a "thousandth of one inch") ie. The resistances and skin depth noted are for copper conductors. 12 AWG - maximum of 25 Amps in free air, maximum of 20 Amps as part of a 3 conductor cable; The table below is a guide only and there are many factors such as alloy composition, ambient temperature and airflow which come into play. The n gauge wire diameter d n in millimeters (mm) is equal to 0.127mm times 92 raised to the power of 36 minus gauge number n, divided by 39: Because of the small gaps between the strands in a stranded wire, a stranded wire with the same current-carrying capacity and electrical resistance as a solid wire, always have a slightly larger overall diameter.
