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 .

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] .

The following calculator calculates the voltage drop, and voltage at the end of the wire for American Wire Gauge from 4/0 AWG to 30 AWG, aluminum or copper wire.

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) to mm and mm2 conversion calculator, chart and how to convert.

Maximum current (amps) in a 12V electrical circuit vs. size (AWG) and length of wire. Electrical resistance in plain copper or aluminum wires. The AWG (American Wire Gauge) wire size chart with detailed specifications on wire diameter, resistance, and ampacity.

The AWG (American Wire Gauge) wire size chart with detailed specifications on wire diameter, resistance, and ampacity. Find conversions between AWG sizes and metric units for electrical and engineering applications.

20 Amps Wire Size: AWG Gauge, Breaker, Suggestion For 220V-240V Circuit. If you’re looking for wire size for a 20 amp circuit (this can be for a 20 amp 220-volt circuit, breaker, battery output), you will need an AWG with at least 20 amp rated ampacity at 75°C.

The American wire gauge (AWG), also known as the Brown & Sharpe wire gauge, is a standardized system for defining the diameter of conductive wires. The table below is a guide only and there are many factors such as alloy composition, ambient …

Example: 12 AWG wire has a diameter of over 2 mm and 20 AWG has a below 1 mm diameter. In theory, you convert AWG gauge to mm using this somewhat complex AWG to mm formula: In practice, we prefer to use a simple AWG to mm chart. Here is the full chart for all AWG gauge wires to mm: This chart is simple to use.
