AWG To mm2 Chart + Calculator (0-40 AWG To mm2)

Both AWG and mm2 are measures for the size of the wire, either diameter (AWG) or cross-section (mm2).

AWG stands for American Wire Gauge and is directly connected with a diameter of a wire. From that diameter, you can calculate what the cross-section of the wire is. Basically, you convert AWG to mm2.

The AWG to mm2 formula is quite complex:

In practice, nobody uses this equation. We usually use two very simple resources:

1. AWG to mm2 chart. This basically tells you how many mm2 is an AWG wire (cross-section).
2. AWG to mm2 calculator. You insert the AWG wire size and the calculator will tell you how many mm2 is the cross-section of that AWG wire.
3. Rules of thumb to convert AWG to mm2 easily. Example: If mm2 is doubled, the AWG increased by 3. 14 AWG wire has a 2.08 mm2 cross-section. An 11 AWG wire (AWG increased by 3) has a 4.17 mm2 cross-section; double that of 14 AWG.

To help you out, we have listed both the chart and the calculator below:

AWG To mm2 Chart

This chart is very simple to use. Just find out the AWG wire and see how many mm2 cross-section it has.

Example: 10 AWG has a cross-section of 5.26 mm2.

An even simpler way to convert AWG to mm2 is to use this AWG to mm2 calculator:

Just insert AWG and you will get the mm2:

Hopefully, you can use the chart and calculator to figure out how many mm2 does an AWG gauge wire has.
