AWG24, AWG30, American Wire Gauge
American Wire Gauge Conversion Chart (AWG)
American wire gauges (AWG) are a standard set of sizes for wire conductors — the smaller the wire gauge, the larger the diameter in inches or millimeters, and vice versa. Refer to this American wire gauge conversion chart to help determine the correct wire size to order.
