American Wire Gauge (AWG) Sizes and Properties Chart / Table Table 1 lists the AWG sizes for electrical cables / conductors. In addition to wire size, the table provides values load (current) carrying capacity, resistance and skin effects. The resistances and skin depth noted are for copper conductors. A

The following chart is a guideline of “ampacity”, or copper wire current-carrying capacity following the Handbook of Electronic Tables and Formulas for American Wire Gauge. As you might guess, the rated “ampacities” are just a rule of thumb.

The AWG - American Wire Gauge - is used as a standard method denoting wire diameter, measuring the diameter of the conductor (the bare wire) with the insulation removed. AWG is sometimes also known as Brown and Sharpe (B&S) Wire Gauge. The AWG table below is for a single, solid, round conductor.

AMERICAN WIRE GAUGE (AWG/KCMIL) TO MILLIMETERS SQUARED (mm2) Based on UL and international standards, there is not a direct conversion or equivalency from AWG/kcmil to metric (mm2), but UL 83 standard provide closest sizes between AWG or kcmil to mm2.

AWG is a standard denoting wire diameter, whereas the metric conductor sizes according to standard IEC 60228 describe a wire in terms of its cross-sectional area, rather than its diameter, because the cross section is directly proportional to its strength, weight, and resistance.

AWG - American Wire Gauge - is used as a standard method for determining diameters of single, solid, bare (non-insulated) aluminum wires. AWG is sometimes also referenced as Brown and Sharpe (B&S) Wire Gauge.

Wire Gauge Table. Most of the wire and cable made in the U.S. use the American Wire Gauge (AWG) system. In the rest of the world conductors are measured in square millimeters. The use of a geometric size progression makes for an easy transition between sizes based on current carrying capabilities.
