NOTE · USING THIS CONVERTER
For US NEC installations, AWG is the dominant unit. For EU/IEC imports, mm² is standard. Use this converter when matching foreign motor specifications, importing equipment, or working with international design standards. See AWG explained for the history of the gauge system.
