The AWG system
The Anglo-Americans use a specific gauge system to define the diameters of wires and tubes (in English, this term translates to gauges
). The most well-known is the AWG system (USA: American Wire Gauge). In pre-war literature, other systems can be found. A tool is provided below that converts each gauge number into the corresponding diameters in mm and inches. But first, a brief explanation of these gauges.
The American system (A.W.G.), despite its peculiarities, was designed with the following clever principle: every time you move down three lines in the table, the cross-section and thus the weight per meter are approximately halved. Therefore, knowing three successive gauges well allows you to estimate the approximate values of nearby gauges.
Gauge Conversion Tool (millimeters and inches)
Select a gauge number. Then check the equivalences in mm in the table below.
