This table gives closest equivalent size cross references between metric and american wire sizes. American wire gauge awg metric wire gauge wire sizes. Current rating 2 cables single phase.

American wire gauge awg sizes may be determined by measuring the diameter of the conductor the bare wire with the insulation removed. These are mostly used for appliances and objects that require much more electrical power to operate or special use situations. No nominal diameter of wires. Awg to metric conversion chart.

In europe wire sizes are expressed in cross sectional area in mm and also as the number of strands of wires of a diameter expressed in mm. Refer to the wire gauge diameter table for dimensions. Imperial sizes bss 2004 metric sizes bss 6004. What about other cable sizes.
