AWG Wire Sizes (see table below)
American Wire Gauge every 6 gauge decrease gives a doubling of the wire diameter, and every 3 gauge decrease doubles the wire cross sectional area – just like calculating dB’s in signal levels. Metric Wire Gauges (see table below) Metric Gauge: In the Metric Gauge scale, the gauge is 10 times the diameter in millimeters, thus
