American Wire Gauge (AWG) Diameter Chart
When producing wire for North American markets, AWG (American Wire Gauge) is the most widely used standard. Unlike metric systems, AWG uses numbers to define wire diameter: the higher the AWG number, the thinner the wire.

This chart is widely used in wire drawing, galvanized wire, construction wire, and hardware exports.
