Convert American Wire Gauge to metric cross-sectional area
Convert metric wire sizes to American Wire Gauge equivalent
2.5 mm² wire is closest to 13 AWG. Since 13 AWG is not a standard US size, the nearest standard AWG equivalents are 12 AWG (3.31 mm², slightly larger) or 14 AWG (2.08 mm², slightly smaller). Use 12 AWG as the safe choice when substituting.
10 AWG wire has a cross-sectional area of 5.26 mm². The nearest IEC 60228 standard size is 6 mm² (slightly larger). 10 AWG is commonly used for 30A circuits in the US — equivalent to roughly a 6 mm² conductor in metric systems.
6 AWG wire has a cross-sectional area of 13.3 mm². The nearest IEC 60228 standard size is 16 mm² (closest, slightly larger). 6 AWG copper wire handles 65A at 75°C and is used for 50–60A circuits (ranges, hot tubs, EV chargers).
