There are two main systems or measurements used for defining the size of cables or wires used for electrical and electronic equipment. These wires and cables are used in all areas of radio, electronics and electrical work.
The table below gives a cross reference between the American Wire Gauge (AWG) system and the metric system where wire and cable sizes are measured by their cross-sectional area in square millimeters. This chart is for the measurments of Magnet wire, used for Coils. The table with approximate equivalents for wires and cables is given below, and RED are most popular for Coils.
For the wires and cables defined under the AWG system, the gauge numbers applied to the wire are for the overall wire with an equivalent size. This means that the gauge size only determines its overall cross sectional area, and not its physical construction.

ohms / km
While every effort has been made to ensure the correctness of the wire and cable data, no responsibility can be accepted for any errors
or the consequences of any errors!
