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 .

In these AWG gauge charts, most common gauge values show the different characteristics of wire such as its diameter, area, ampacity, resistance, current density, fusing current and temperature ratings etc.

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.

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).

In this AWG wire gauge chart for a standard copper wire, you can find every AWG wire; from the biggest 10+ mm wires (such as 4/0 AWG and 3/0 AWG wires) to the smallest below 0.01 mm wires like 39 and 40 AWG wires.

2024年8月12日 · 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.

Table 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.

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.

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.
