Wire Gauge Calculator

Online AWG diameter calculator to find the diameter of the wire in gauge (AWG). Wire gauge is nothing but the measurement of length of the wire, in either of diameter or cross-sectional area. It helps to determine the actual amount of electric current that a wire can safely carry and in turn it finds the wire area (i.e) weight per unit of length. It is applicable for both electrical and non-electrical wires. Enter the diameter of the wire in this wire gauge calculator to get the result.
