What this tool does

Convert American Wire Gauge number to bare conductor area. Insulation diameter is not included. Fractional AWG yields a mathematical interpolation, not a manufactured size.

How to use the AWG to mm2 Converter

  1. Enter or select awg number (0 = 1/0).
  2. Read the calculated result; change any measurement to compare alternatives.

Formula

diameter(mm)=0.127×92^((36−AWG)/39); area(mm²)=π×diameter²/4
awg
AWG number (0 = 1/0)

Insulation diameter is not included. Fractional AWG yields a mathematical interpolation, not a manufactured size.

Worked example

For awg to mm2 converter, the following measurements illustrate the exact method: AWG number (0 = 1/0): 12.

Inputs

  • AWG number (0 = 1/0)12

Result

  • Cross-sectional area (mm²)3.31
  • Bare diameter (mm)2.05

Results explained

Cross-sectional area (mm²)
Cross-sectional area (mm²) from the formula above. Insulation diameter is not included. Fractional AWG yields a mathematical interpolation, not a manufactured size.
Bare diameter (mm)
Bare diameter (mm) from the formula above. Insulation diameter is not included. Fractional AWG yields a mathematical interpolation, not a manufactured size.

No. Electrical and HVAC results are estimates. Installation must comply with local codes and be checked by a qualified licensed professional.

Nameplate values, conductor temperature, power factor, efficiency, weather and actual installation conditions may differ from your entered assumptions.

Confirm units, manufacturer data and the formula's assumptions, then verify sizing with the equipment instructions and applicable local standards.
