AWG to Metric Conversion Chart and Table

awg metric conversion wire size cable

This page provides an AWG to Metric conversion chart and table. The table takes AWG as input and provides the corresponding cable diameter (in inches and mm) and cable cross-sectional area (in square mm) as outputs. Table 1 (below) shows the input and outputs needed to convert AWG to metric equivalents (inch, mm, and square mm).

This conversion is specifically for cables made of copper. The following equations can be used to convert AWG to metric units:

  • Cable Diameter, Dn (mm): 0.127 x 92(36-n)/39
  • Cable or Wire Cross-Sectional Area, An (in square mm): (π/4) * Dn2
  • Cable Diameter, Dn (inch): 0.005 x 92(36-n)/39
