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 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).
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. Dimensions of the wires are given in ASTM standard B 258. [1] .
AWG Wire size chart and ampacity table for design engineers including skin depth frequencies and tensile strength data; electrical cable size
Here is the full AWG wire size chart (including wire ampacity chart): 4/0 or 0000 AWG gauge wire is the thickest wire used in the standard AWG (ie. Brown & Sharpe wire gauge) system. It is one of the two AWG wires that have a 10+ mm diameter (4/0 AWG wire to mm equals 11.684 mm).
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.

Wire gauge refers to the physical size of the wire, rated with a numerical designation that runs opposite to the diameter of the conductors—in other words, the smaller the wire gauge number, the larger the wire diameter. Common sizes include 16-, 14-, 12-, 10-, 8-, 6-, and 2-gauge wire.
A wire gauge chart lists the American Wire Gauge (AWG) sizes for electrical cables and converts them to inches and millimeters. Wire properties such as cross-sectional area, ampacity and resistance are also listed.
Typical household wiring is AWG number 12 or 14. Telephone wire is typical AWG 22, 24, or 26. The table below indicates the current ratings of PVC-insulated single and multicore wiring cables. Be aware that the current load depends on installation method - the enclosure - and how well the resistance heat is removed from the cable.
