Product Information

The n gauge wire resistance R in ohms per kilometer (Ω/km) is equal to 1000000000 times the wire's resistivity ρ in data-src="https://cdn.media.amplience.net/i/washford/Halfords Car Audio fitting & installation service" in millimeters (mm) is equal to 0.127mm times 92 raised to the power of 36 minus gauge number n, divided by 39:

The AWG - American Wire Gauge - is used as a standard method denoting wire diameter, measuring the diameter of the conductor (the bare wire) with the insulation removed. AWG is sometimes also known as Brown and Sharpe (B&S) Wire Gauge. The higher the number - the thinner the wire. Typical household wiring is AWG number 12 or 14. Telephone wire is typical AWG 22, 24, or 26. The most common method of referring to conductor sizes uses the cross-sectional area, expressed in mm². The following AWG metric conversion table converts AWG to mm and inches, and also lists the cross sectional area (mm2). AWG Metric Conversion Chart (AWG to mm) 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 cross-sectional area of each gauge is an important factor for determining its current-carrying capacity. If this AWG metric calculator doesn't provide you with the information you need, please get in touch with the technical experts of The Cable Lab who will be pleased to answer your questions or calculate the appropriate AWG/metric size for your installation.The wire size chart below shows allowable ampacities of insulated conductors rated up to and including Wire Gauges run low to high - this means that the smaller a gauge number, the larger it is in mm. Conversely, a large number in AWG equates to a very small number of mm. In the US, the most commonly used wire gauge system is AWG, or American Wire Gauge. The higher the gauge number, the smaller the wire.

When calclating AWG from diameter or cross sectional area, the diameter and cross sectional area are rounded to the nearest AWG equivalent values. Wire diameter calculation Values for resistance are based on electrical resistivity for copper 1.724 x 10 -8 Ω m (0.0174 μΩ m) and electrical resistivity for aluminum 2.65 x 10 -8 Ω m (0.0265 μΩ m).

What is AWG? The AWG standard was created by the Brown & Sharpe Company, a leading manufacturer of machinist technology in the late 1800s & early 1900s. The AWG standard was officially adopted & implemented as industry-standard sizing in 1857. Unfortunately, AWG does not fit comfortably in rounded mm or inches, so there will always need to be a small amount of rounding up or down depending on your need or purpose. If you want the technical formulae for converting between the two, it is as follows; The largest diameter AWG size is 0000 (4/0) which is pronounced ‘four aught’, representing a diameter of .46″. The smallest diameter is 32 AWG, representing .00795″. The AWG table below is for a single, solid, round conductor. Because of the small gaps between the strands in a stranded wire, a stranded wire with the same current-carrying capacity and electrical resistance as a solid wire, always have a slightly larger overall diameter. Calculate the number of small circles that fits into an outer larger circle - ex. how many pipes or wires fits into a larger pipe or conduit.
