2 AWG to mm² – Wire Size & Diameter
2 AWG = 33.631 mm²
2 AWG solid wire has a cross-section of 33.631 mm² and a diameter of 6.544 mm (0.2576 in).
Step by step
- Diameter: d = 0.127 × 92^((36 − 2)/39) = 6.5437 mm.
- Area: π/4 × d² = 33.6308 mm².
2 AWG is a heavy gauge for feeders, service entrances, batteries and welding cables.

How it works
The American Wire Gauge system is logarithmic: smaller numbers mean thicker wire, every 6 gauges halve the diameter and every 3 gauges roughly halve the area. Metric wire is specified directly by cross-sectional area in mm², so the sizes never line up exactly. When substituting, choose a conductor with at least the same area, and always follow local electrical codes.
