AWG is shown below with its exact equivalent value in mm² and diameter (mm). AWG is the exact corresponding value in mm² + diameter in mm. The following AWG table shows an overview of the common AWG values in mm². The table comparing European and American strands contains the corresponding commercially specified values, which are approximate values.

4/0 is also known as 0000; 1 mil = inch = 0,0254 mm
*shown in MCM (circular mills) for bigger cross sections
1 CM = 1 Circ. mil = 0,0005067 mm²
1 MCM = 1000 Circ. mils = 0,5067 mm²
