* Diameter and area values are rounded to fit the nearest AWG value.
** The diameter and area of the conducting wire without insulation.
When calclating AWG from diameter or cross sectional area, the diameter and cross sectional area are rounded to the nearest AWG equivalent values.
The n gauge wire diameter dnin millimeters (mm) is equal to 0.127mm times 92 raised to the power of 36 minus gauge number n, divided by 39:
dn (mm) = 0.127 mm × 92(36-n)/39
0.127mm is the diameter of gauge #36.
The n gauge wire's cross sercional area Anin square millimeters (mm2) is equal to pi divided by 4 times the square wire diameter d in millimeters (mm):
An (mm2) = (π/4)×dn2= 0.012668 mm2 × 92(36-n)/19.5
