American Wire Gauge Conversion Calculator

Most of our UK, US and international buyers find it difficult when confronted with AWG sizing or mm. This tool helps in calculating the nominal equivalent values of wire sizes, such as American Wire Gauge [AWG], Square Millimeter Area [mm2], Circular Mil Area [CMA], and more. Simply enter the known measurement or value and all of the equivalent values will be automatically calculated and displayed.

Please enter your values below:

(conversions are rounded to the nearest AWG number)
