Use the calculator below to convert  wire size in AWG  to sq.mm, mm, inch and  kcmil.

You can also use the formulas below to convert AWG wire size  to sq.mm, mm, inch and  kcmil.

Formula: Convert AWG wire size to inches

To convert an AWG size to inches for AWG sizes 0 to 36, use the formula:

  • AWG no= 0.005 inch x 92(36-n)/39  where n in the AWG no.

For example, using the formula:

AWG 5 = 0.005 x 92(36-5)/39=0.005 x 92 (31)/39 =0.005*36.38811=0.181941 inches.

Formula: Convert AWG wire size to mm

While to convert an AWG size to mm for AWG sizes 0 to 36, use the formula:

  • AWG no= 0.127 x 92(36-n)/39 where n in the AWG no.

So, to find the equivalent wire size in mm for AWG no. 5

    =0.127 x 92(36-5)/39= =0.127 x  36.38811 =4.621 mm
