AWG to Metric Conversion Chart
Reference and Sources:
Wikipedia: American wire gauge
American Wire Gauge (AWG) & Metric Wire Gauge Wire Sizes
Van den Hul: AWG to Metric Conversion Chart
This table gives closest equivalent size cross references between metric and American wire sizes. In Europe, wire sizes are
expressed in cross sectional area in mm and also as the number of strands of wires of a diameter expressed in mm. For
example 7/0.2 means 7 strands of wire each 0.2mm diameter. This example has a cross sectional area of 0.22mm. In
America, the commonest system is the AWG numbering scheme, where the numbers are applied not only to individual strands
but also to equivalent size bunches of smaller strands. For example 24AWG could be made of 1 strands of 24AWG wire (1/24)
or 7 strands of 32 AWG wire (7/32).
