AWG means American Wire Gauge which is used as a standard for measurement of wire's gauge. The quality of wires is judged by the wire gauge, diameter of wire & their cross-section area. On this page, you can calculate the diameter and cross-section area from the wire gauge as well as the wire gauge from the diameter & cross-section area.
Moreover, you can also estimate the total area of wire via the below-given calculator by just providing the AWG value of the wire.
Put in the desired entities you wanna convert & click on the calculate button:
* Diameter and area values are rounded to fit the nearest AWG value.
** The diameter and area of the conducting wire without isolation.
When calculating 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 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 wire's cross sercional area An in 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

Both measurement wire cross-area and wire outside breadth can be determined by recipes utilizing only the AWG number. The equation for the wire outside distance across is: 0.127 mm * 92(32-n)/39 .
