Convert an American Wire Gauge (AWG) number to wire diameter in inches and millimeters, plus cross-sectional area in square millimeters, using the standard AWG formula.
Formula
D(in) = 0.005 × 92^((36-AWG)/36)Step-by-step
- Diameter (in) = 0.005 × 92^((36−AWG)/36)
- Diameter (mm) = Diameter (in) × 25.4
- Area (mm²) = π × (Diameter/2)²
Example
12 AWG wire = 0.0808 in (2.053 mm) diameter, 3.309 mm² area.
