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.

Use to convert wire size to millimeters of diameter and CMA. Use to select the proper size terminals or splices.

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 .

2021年8月13日 · 美国线规（英文是 American wire gauge，缩写为A WG），是一种区分导线直径的标准，又被称为 Brown & Sharpe线规。这种标准化线规系统于1857年起在美国开始使用。导线的直径与导线承载电流的能力有很大关系。

This tool is used to calculate the nominal equivalent values of wire sizes such as American Wire Gauge [AWG], Square Millimeter Area [mm 2], Circular Mil Area [CMA], and more. Just put in a known measurement or value and all of the equivalent values …

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. (Note: It just calculates the voltage drop, consult the above table for rules-of-thumb, or your local or national electrical code or your electrician to decide what is legal!)

American Wire Gauge (AWG) is a standardized wire gauge system used predominantly in the United States to note the diameter of electrically conducting wire. The general rule of thumb is when the diameter of a wire is doubled, the AWG will decrease by 6. (E.g. No. 2 AWG is about twice the diameter of No. 8 AWG.)

The biggest AWG wire (4/0 AWG) is equal to 211,592 circular mils (this could be called 211 kcmil wire). The next wire by thickness is called 250 kcmil wire . We go from AWG directly to thousands of circular mils (abbreviated as kcmil).

2025年2月21日 · In the United States, the American Wire Gauge is used. It is a scale of even numbers that start with the number 40 and descend. The cross-sectional area becomes larger as the numbers on this scale get smaller. For wires larger …
