Nearest metric sizes

13.30 mm² does not match a standard metric cable size exactly. The closest conventional cross-sections are6 mm², 10 mm² and 16 mm²— engineers round this wire up (larger cross-section) for ampacity, or accept the raw equality for signal work.

Frequently asked questions

Is 6 gauge wire thick or thin?

6 gauge wire is 4.12 mm in diameter. On the AWG scale a lower number means a thicker wire, so 6 AWG sits toward the thick end, where service and feeder wires live.

How many amps can 6 gauge wire carry?

NEC Table 310.16 rates 6 AWG copper at 65 A in the 75 °C column (see our amp chart for 60/75/90 °C ratings). Use the calculator to check voltage drop at your run length; long runs often force one size thicker.

What diameter is 6 wire in millimeters?

6 gauge wire is 4.12 mm (0.162 in) in diameter, with a solid-conductor cross-section of 13.30 mm².
