You can use the calculator below to convert your wire sizes in AWG to either **sq.mm, mm, inches, or kcmil**. Alternatively, if you prefer for whatever reason, the actual formulas are also provided and can be used to complete the **conversion manually**.

## Formula for Converting AWG to Inches

To convert an **AWG wire size to inches**, use the conversion below:

*AWG no = 0.005 inch x 92(36-n)/39, where ‘n’ represents the AWG number.*

For example:

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

## Formula for Converting AWG to mm

To convert **AWG size to mm**, use the formula below:

*AWG no = 0.127 mm x 92(36-n)/39, where ‘n’ is the AWG number.*

Using AWG wire size 5 as an example, the equivalent diameter in mm is:

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

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*
