How do you convert AWG to mm?

The converter uses the standard AWG diameter equation, then derives metric diameter, area, and circular mil values from that geometry.

Does this page also convert mm² to AWG?

Yes. You can enter metric diameter or cross-sectional area and the tool will match the nearest AWG or kcmil size.

FAQ

AWG conversion notes

Why show both mm and inches at the same time?

Because job-site and procurement work often crosses standards. Showing both removes a round-trip and keeps the page more useful.

Why is SWG shown as a nearest match rather than a perfect conversion?

SWG and AWG are separate systems. A nearest match is usually the practical answer, but it should not be treated as an exact standard substitution.
