AWG (AMERICAN WIRE GAUGE) TO
METRIC CONVERSION CHART
AWG (American Wire Gauge) is used predominantly in North America for wire outside diameter and cross-section. Dimensions are defined by the ASTM B258 standard. AWG sizes with multiple zeros can be designated as number of zeros or number of zeros/0. Both metric wire cross-section and wire outside diameter can be calculated by formulas using just the AWG number. The formula for the wire outside diameter is: 0.127 mm * 92(32-n)/39 [mm]. The formula for metric wire cross-section is: 0.012668 mm2 * 92(36-n)/19.5 [mm2]. In both formulas, n is the AWG number.
