AWG (American Wiring Gauge)

It is also called BS (Brown & Sharp Wire gauge), and it is assigned so that the area between 5 [mil] in diameter and 460 [mil] in diameter of a solid wire conductor is 36 AWG and 4/0 AWG, respectively, in geometrical progression.

• *1 [mil] = 1/1000 [inch]

From this value, the cross sectional area of the lead wire can be obtained as follows.
