AWG Guide
What is AWG?
American Wire Gauge. Smaller numbers mean thicker wires. Wires thicker than 0 are denoted as 2/0, 3/0, 4/0.
Area Formula
AWG area (kcmil) = 1000 × (diameter in mils)². 1 kcmil = 0.5067 mm²
What is the Wire Size Converter?
A tool that converts between wire gauge units including AWG (American Wire Gauge), mm² (square millimeter), and kcmil (MCM). Provides comprehensive information about wire specifications including cross-sectional area, diameter, resistance, and ampacity.
