A standard wire gauge. British Standard Wire Gauge (often abbreviated to Standard Wire Gauge or SWG) is a unit for denoting wire size given by BS 3737:1964 (now withdrawn). It is also known as the Imperial Wire Gauge or British Standard Gauge. Use of SWG sizes has fallen greatly in popularity, but they are still used as a measure of thickness ...
The Imperial Standard Wire Gauge, which was sanctioned by the British Board of Trade in 1884, was formulated by J. Latimer Clark. Following one of its recommendations, it differs from pre-existing gauges scarcely more than they differ among themselves, and is based on a rational system, the basis being the circular mil .
Comparison of SWG (red), AWG (blue) and IEC 60228 (black) wire gauge sizes from 0.03 to 200 mm² to scale on a 1 mm grid – in the SVG file, hover over a size to highlight it. In engineering applications, it is often most convenient to describe a wire in terms of its cross-section area, rather than its diameter, because the cross section is directly proportional to its strength and weight ...

AWG is colloquially referred to as gauge and the zeros in thick wire sizes are referred to as aught / ˈ ɔː t /. Wire sized 1 AWG is referred to as "one gauge" or "No. 1" wire; similarly, thinner sizes are pronounced "x gauge" or "No. x" wire, where x is the positive-integer AWG number. Consecutive AWG wire sizes thicker than No. 1 wire are ...
IEC 60228, the metric wire-size standard used in most parts of the world. American Wire Gauge (AWG) , used primarily in the US and Canada Standard Wire Gauge (SWG) , the British imperial standard BS3737, superseded by the metric.
Discussions of gauge in this article use the American Wire Gauge (AWG) scale. Some jewelry may use the significantly different Standard Wire Gauge (SWG) scale instead, particularly jewelry from Canada or the United Kingdom where the SWG scale is used. [2] Both AWG and SWG express sizes as a gauge, but the numbers are different.
