- diameter (mm) = 0.127 × 92^((36 − n) ÷ 39). A smaller AWG number means a thicker wire.
Good to know: AWG 10 is 2.588 mm across, about 5.26 mm².
Questions people ask
What diameter is AWG 10?
2.588 mm, with a cross-section of about 5.26 mm².
Why is a smaller AWG number thicker?
AWG counts drawing steps: each time the wire is drawn through a die it gets thinner and the number rises, so low numbers are thick wire.
Does the table work for stranded wire?
Stranded cable is sized by total copper cross-section, so use the mm² column; the stranded bundle’s outer diameter is larger than the solid-wire value.
