Wire Gauge

​Wire gauge is the measure of the diameter of wire or the thickness of a sheet of metal.  The American standard is the Brown & Sharpe measurement system.  Under this system, the higher the gauge number the thinner the wire or metal sheet. 
 
The following chart shows the wire gauges I routinely use and their sizes in inches and millimeters.
