* Diameter and area values are rounded to fit the nearest AWG 值.
** The diameter and area of the conducting 线径 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 线径 diameter dn in 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 线径's cross sercional area An in square millimeters (mm2) is equal to pi divided by 4 times the square 线径 diameter d in millimeters (mm):
An (mm2) = (π/4)×dn2 = 0.012668 mm2 × 92(36-n)/19.5
