AWG Wire Size Converter
Choose an AWG number to view wire diameter, cross-sectional area, circular mils, copper resistance per meter, and reference ampacity. Current rating depends on insulation, temperature, wiring method, and standards.

How to Use
- Select an AWG size.
- Review diameter in mm and inches and area in mm².
- Check resistance per meter and reference ampacity.
Examples
- Check diameter and area for AWG 24
- Compare AWG 0 and AWG 00 wire sizes
Calculation and Conversion Notes
AWG wire diameter is calculated with `d(inch) = 0.005 × 92^((36 - AWG) / 39)`. Cross-sectional area and copper resistance are reference values derived from the calculated diameter. Current rating depends on insulation, temperature, wiring method, and standards, so it should be verified separately.
