Use this AWG to mm² calculator to convert between two different wire sizing systems: the American Wire Gauge (AWG) and metric square millimeter (mm²) measurement.

The AWG system is predominantly used in North America and dates back to 1857. It uses a logarithmic scale to denote wire diameters, with lower numbers indicating thicker wires. For example, AWG 0 is thicker than AWG 10.

AWG to mm² Conversion Formula

The general formula to convert AWG to mm² is:

A = π * (d/2)²

Where:

  • A is the cross-sectional area in mm²
  • d is the diameter of the wire in mm

To find d, we use the AWG number in the following formula:

d = 0.127 * 92^((36-n)/39)

Where n is the AWG number.

Combining these formulas, we get:

A = π (0.127 92^((36-n)/39) / 2)²

This formula can be simplified to:

A ≈ 0.012668 * 92^((36-n)/19.5)

While this formula provides the exact conversion, it’s important to note that in practical applications, wire sizes are often rounded to standard values.
