*AWG stands for American Wire Gauge, a standard used to measure the diameter of electrical wire. The larger the AWG number, the smaller the wire’s diameter. To convert AWG to mm, you can use an online conversion chart. For instance, AWG 10 corresponds roughly to 2.588 mm, while AWG 20 is around 0.812 mm.*
