Wire Size Calculator

Wire Gauge Calculator mainly calculates the diameter of a wire, which in turn helps in the measurement of cross-sectional area and resistance of a wire. American Wire Gauge is the wire gauge standard used in North America.

The formula for Calculating Wire Diameter in mm:

Wire Diameter (mm) = .127 × 92(36 – AWG) ÷ 39

The formula for Calculating Cross-Sectional Area in mm2:

Cross-Sectional Area (mm2) = (π ÷ 4) × Diameter2

Diameter, cross-sectional area, and resistance values for different American wire gauge (AWG) values.
