# AWG To mm Chart (0-40 AWG Gauge Wires To mm)

Both AWG and mm are basically a measure of wire diameter (thickness). AWG or American Wire Gauge is a diameter unit used predominantly in the US, while a metric mm (millimeters) is used around the world. In many cases, you will need to convert AWG to mm like this:

In theory, you convert AWG gauge to mm using this somewhat complex AWG to mm formula:

In practice, we prefer to use a simple AWG to mm chart. Here is the full chart for all AWG gauge wires to mm:

 AWG Wire Gauge: mm (Diameter): 0000 (4/0) AWG 11.684 mm 000 (3/0) AWG 10.405 mm 00 (2/0) AWG 9.266 mm 0 (1/0) AWG 8.251 mm 1 AWG 7.348 mm 2 AWG 6.544 mm 3 AWG 5.827 mm 4 AWG 5.189 mm 5 AWG 4.621 mm 6 AWG 4.115 mm 7 AWG 3.665 mm 8 AWG 3.264 mm 9 AWG 2.906 mm 10 AWG 2.588 mm 11 AWG 2.305 mm 12 AWG 2.053 mm 13 AWG 1.828 mm 14 AWG 1.628 mm 15 AWG 1.450 mm 16 AWG 1.291 mm 17 AWG 1.150 mm 18 AWG 1.024 mm 19 AWG 0.912 mm 20 AWG 0.812 mm 21 AWG 0.723 mm 22 AWG 0.644 mm 23 AWG 0.573 mm 24 AWG 0.511 mm 25 AWG 0.455 mm 26 AWG 0.405 mm 27 AWG 0.361 mm 28 AWG 0.321 mm 29 AWG 0.286 mm 30 AWG 0.255 mm 31 AWG 0.227 mm 32 AWG 0.202 mm 33 AWG 0.180 mm 34 AWG 0.160 mm 35 AWG 0.143 mm 36 AWG 0.127 mm 37 AWG 0.113 mm 38 AWG 0.101 mm 39 AWG 0.0897 mm 40 AWG 0.0799 mm

This chart is simple to use.

Example: How many mm is an 8 AWG wire? 8 AWG wire is 3.264 mm.

You can do this for literally AWG wire you need to convert to mm.

1. Finally an actual formula! Trying to figure out the AWG of the 0.007mm diameter wire I use for nanosoldering. According to this formula, 61 AWG. Thanks.
