formula

AWG equivalence

The AWG-to-diameter in inch/mm conversion formula is $$d = 0.005inch \cdot 92^{\frac{36-n}{39}} = 0.127mm \cdot 92^{\frac{36-n}{39}}$$ Inversely, the diameter in inch/mm-to-AWG conversion formula is $$n = -39log_{92}\left(\frac{d}{0.005inch}\right) + 36 = -39log_{92}\left(\frac{d}{0.127mm}\right) + 36$$
