What do the gauge numbers mean? - 翻译中...

The American Wire Gauge system is based on a total of 44 standardized wire sizes: 0-40, as well as the additional 00, 000, and 0000 gauges (the thickest of all). It may seem a little counterintuitive, but the higher a gauge number is, the thinner the wire will be. This is because each gauge is named after the number of sizing dies the wire needs to be drawn through to reach the correct diameter (for example, a 24 gauge wire is drawn through 24 different sizing dies).
