American Wire Gauge (AWG) or Brown & Sharpe wire gauge: It is a standard tool which is circular in shape and has various slots of different diameter in its circumference.

It is generally used for precious metals, non-ferrous, cable or wire. AWG is still widely used in electrical wires while not so much SWG.

Fomulas:

Wire Diameter:

dn = 0.127 mm x 92^((36-n)/39) =0.005 inch x 92^((36-n)/39)

dn is wire Diameter in (mm), Diameter in (inch)

n is AWG (American Wire Gauge) wire size

Wire Cross Section Area:

An = (3.1415/4) x dn x dn
