AWG to mm2 - wire gauges

This table with wire gauges comes handy when buying wires. A lot of folks get into electronics through keyboard building, and knowing the diameter or cross-section of an AWG gauge helps to compare different offers.

You probably should choose from this short list of diameters when handwiring a custom keyboard:

AWG #	Diameter [mm]	Area [mm²]	Diameter [inch]	Info
22	0.6438	0.3255	0.0253	This is the common breadboard jumper wire's gauge.
23	0.5733	0.2582	0.0226
24	0.5106	0.2047	0.0201
25	0.4547	0.1624	0.0179
26	0.4049	0.1288	0.0159	This is the thinner gray HDD ribbon cable's gauge.
27	0.3606	0.1021	0.0142
28	0.3211	0.0810	0.0126
29	0.2859	0.0642	0.0113
30	0.2546	0.0509	0.0100
