AWG to mm Conversion

It is a conversion calculator used to convert the values in American Wire Gauge (AWG) to millimeters (mm). This converter has two text fields and control buttons that are used to execute different actions during the calculations. The first step of using the AWG to mm calculator is by selecting the gauge number which lies in the range of 0 to 40. In case you have a gauge number that goes beyond 40, you will enter it in the second field. (Enter gauge #).

Click the ‘Calculate’ button to perform the conversion. It executes the conversions within a single click displaying the result in millimeters (mm). You will also get the cross sectional area in square millimeters which is calculated automatically with the diameter in millimeters. If you need to perform new calculations, you will use the ‘Reset’ button to clear all the text fields of the previous calculations.

Converting AWG to mm

The converter utilizes particular formulas in carrying out the calculations;

Dn (mm) = 0.127 mm x 92 (36-n)/39, which means that the n gauge wire diameter in millimeters is calculated by multiplying 0.127 mm by 92 (36-n)/39. The diameter of the gauge number 36 is 0.127 millimeters (mm).

Calculating the wire cross sectional area

An (mm2) = (∏/4) x dn2 = 0.0012668 mm2 x 92 (36-n)/19.5, which means that the n gauge wire’s cross sectional area An in square millimeters is computed by multiplying the square wire diameter in millimeters by pi divided by 4.

For example;
If the American wire gauge is 56 (AWG), find the diameter in millimeters and the Cross sectional area in square millimeters.

The gauge number is more than 40 and hence you will enter the value in the blank text field. Click the calculate button and your results will be;

Diameter in millimeters = 0.0125 mm

Cross sectional area in square millimeters = 0.0001 mm2

This calculator only performs conversions from AWG to mm. It can only carry out a single calculation at a time and therefore, you will be required to erase the previous calculations from the text field using the ‘Reset’ button.
