Wire Gauge Converter
Convert between AWG (American Wire Gauge) and mm² cross-section area. Shows diameter in mm and inches, plus copper resistance per kilometer for each gauge size.
How to Use Wire Gauge Converter
The Wire Gauge Converter translates between AWG (American Wire Gauge) numbers and metric cross-section area in mm². Select an AWG gauge to see its diameter in mm and inches, cross-section area, and copper resistance per kilometer. Or enter a mm² value to find the closest AWG equivalent. Covers gauges from 4/0 (largest) to 30 AWG (smallest). Essential for electricians, electronics hobbyists, and engineers selecting wire for circuits, home wiring, or audio installations.
