Wire Gauge Conversion Tables

AWG - American Wire Gauge - is an U.S. standard of wire conductor sizes. The "gauge" is related to the diameter of the wire with a larger "gauge" equal to a smaller diameter and thinner wire. As a global manufacture of cable assemblies and wire harness, Ever First has developed this cross reference between AWG and MM as an easy to use tool.
