Nearest metric size
16 mm²

Solid-conductor dimensions from the AWG formula d = 0.127 mm × 92^((36 − n)/39). Stranded wire is slightly larger overall.

6 AWG = 13.302 mm²

6 AWG solid wire has a cross-section of 13.302 mm² and a diameter of 4.115 mm (0.162 in).

Step by step

  1. Diameter: d = 0.127 × 92^((36 − 6)/39) = 4.1154 mm.
  2. Area: π/4 × d² = 13.3018 mm².

6 AWG copper is common for 50–60 A circuits, EV chargers and subpanels.

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.
