American Wire Gauge (AWG) is a logarithmic stepped standardized wire gauge system used since 1857, predominantly in North America, for the diameters of round, solid, nonferrous, electrically conducting wire.

American wire gauge (AWG) size calculator and chart. * @ 68°F or 20°C. ** Diameter and cross sectional area do not include the insulation. *** Results may change with real wires: different resistivity of material and number of strands in wire. Voltage drop calculator .

The following AWG “American Wire Gauge” table shows the AWG Size and diameter in millimeter “mm” and inches in “in”, its cross sectional area in mm 2, Inche 2 and kcmil or MCM and resistance in ohms per 1000 feet and 1000 meter. The AWG size chart also shows the current in amperes for chassis wiring and power transfer application.

American wire gauge (AWG) is a standardized wire gauge system for the diameters of round, solid, nonferrous, electrically conducting wire. The larger the AWG number or wire guage, the smaller the physical size of the wire. The smallest AWG size is 40 and the largest is 0000 (4/0).

The wire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 Volts, 60°C through 90°C (140°F through 194°F), not more than three current-carrying conductors in raceway, cable, or earth (directly buried), based on ambient air temperature of 30°C (86°F).

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.
