AWG is the US standard that defines the cross-sectional areas and diameters for solid, round electrical wire and is based on the number of dies required to draw down the raw copper to the appropriate size.
Unfortunately, there is no easy way to convert AWG to an exact metric system measurement. Explore our tables below to see close approximations between AWG and metric sizes. If you need exact metric measurements, we recommend referencing data sheets and specifications for the products in question.
