sizes of wire

Best answer


Wire gauges range from low numbers to high numbers,with smaller numbers referring to smaller diameters and larger numbers representing larger diameters. For example,AWG 4 is 0.2043 inchesin diameter,and AWG 40 is .0031 inches in diameter.

  • What is the size of the wire?

  • The larger the AWG number or wire guage, the smaller the physical size of the wire. The smallest AWG size is 40 and the largest is 0000 (4/0). AWG general rules of thumb – for every 6 gauge decrease, the wire diameter doubles and for every 3 gauge decrease, the cross sectional area doubles.

  • How many gauges of wire are there?

  • According to the American Wire Gauge (AWG) method, the highest Gauge of a wire is Nr. 36 AWG, and the smallest Gauge is Nr. 0000. The diameters of these two are 0.005 inches and 0.46 inches, respectively. There are 40 gauges between these largest and smallest sizes, or you can say 39 steps.

  • What is the smallest gauge wire size?

  • The smallest AWG size is 40 and the largest is 0000 (4/0). AWG general rules of thumb – for every 6 gauge decrease, the wire diameter doubles and for every 3 gauge decrease, the cross sectional area doubles.

  • How do you calculate AWG wire size?

  • AWG Wire Sizes (see table below) AWG: In the American Wire Gauge (AWG), diameters can be calculated by applying the formula: D(AWG) = 0.005 * 92 ((36-AWG)/39) inch.
