American Wire Gauge Conversion Chart (AWG) American wire gauges (AWG) are a standard set of sizes for wire conductors â the smaller the wire gauge, the larger the diameter in inches or millimeters, and vice versa. "item": The metric system outside of the Americas uses the cross sectional area in mm 2 to describe how thick a wire is. The AWG is not to be confused with the US Steel, Music Wire, or Washburn and Moen (W&M) gauging methods, which are used only for steel-based wire. { { 0.127mm is the diameter of gauge #36. For example, #10 wire (10 380 CM) has about twice the area of #13 wire (5178 CM) and half the area of #7 wire (20 820 CM). As we go down the chart, we decrease size more and more until we reach a wire size of AWG 40, which is a very small size. Resistivity can be defined in terms of a piece of wire 1 ft long with a cross- sectional area of 1 CM, as shown in Figure 2. A larger AWG number indicates a smaller cable. When made with circular strands, these gaps occupy about 25% of the wire area, thus requiring the overall bundle diameter to be about 13% larger than a solid wire of equal gauge.
