Wire Gauge Calculator – Formula, Free Online Tools, Mobile Apps & FAQs for South Africans

What Is a Wire Gauge Calculator?

A wire gauge calculator is a tool used to determine the diameter of electrical wire based on its gauge number. This is essential when selecting the appropriate wire size for electrical installations, as different wire sizes have different electrical resistance and current-carrying capacities. In South Africa, this calculator is commonly used in household wiring, electrical repairs, and industrial applications.

How to Calculate Wire Gauge Manually

The formula to calculate wire gauge is: Gauge = 39.304 × (diameter in mils) ^ (-0.243) where mil is a unit of length equal to one thousandth of an inch.

For example, if we have a wire with a diameter of 100 mils, the gauge can be calculated as follows:

Gauge = 39.304 × (100) ^ (-0.243) = 17

Therefore, a wire with a diameter of 100 mils corresponds to a 17-gauge wire.
