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) AWG or American Wire Gauge is the US standard measure for the diameter of electrical conductors. The American Wire Gauge chart is based on the number of dies originally required to draw the copper down to the required dimensional size. It means the higher the AWG number is, the smaller the wire diameter is. Our Belden cables and the pairs in instrumentation cable are some of the electrical cables where the conductor size is expressed as an AWG figure. Our Tri-Rated cable, compliant with American standard UL758, can be converted to AWG cable conductor sizes if required. Electric resistance in wire made of Copper, Aluminum, Brass, Constantan, Nichrome, Platinum, Silver or Tungsten.
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. in millimeters (mm) is equal to 0.127mm times 92 raised to the power of 36 minus gauge number n, divided by 39: The n gauge wire resistance R in ohms per kilofeet (Ω/kft) is equal to 0.3048×1000000000 times the wire's resistivity ρ in conductors in raceway, cable, or earth (directly buried), based on ambient air temperature of 30°C (86°F). data-src="https://cdn.media.amplience.net/i/washford/Halfords Car Audio fitting & installation service"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. When buying cut to length electrical wire or electrical cable, many UK and international buyers face difficulty when confronted with AWG sizing. Vice Versa, American buyers may be stumped when they are recommended a certain gauge of cable or wire, and don't know how to get it when confronted with mm. 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 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″. Results may change with real wires: different resistivity of material and number of strands in wireThe n gauge wire diameter d n in millimeters (mm) is equal to 0.127mm times 92 raised to the power of 36 minus gauge number n, divided by 39: For more information regarding wiring and cables, see our comprehensive guide here. AWG Gauge Table AWG gauge The n gauge wire diameter dn in millimetres (mm) is equal to 0.127mm times 92 raised to the power of 36 minus gauge number n, divided by 39: dn (mm) = 0.127 mm × 92(36-n)/39 The AWG gauge system only applies for solid, round, non-ferrous conducting wires. Keep this in mind when evaluating wire size and type for your application, as AWG doesn’t apply to stranded or non-round wires. AWG Gauge Sizes for Home Wiring, Auto Wiring, and Boat Wiring
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. The n gauge wire diameter d n in inches (in) is equal to 0.005in times 92 raised to the power of 36 minus gauge number n, divided by 39: 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 calculationThe AWG tables are for a single, solid and round conductor. The AWG of a stranded wire is determined by the cross-sectional area of the equivalent solid conductor. Because there are also small gaps between the strands, a stranded wire will always have a slightly larger overall diameter than a solid wire with the same AWG. product/helpAdviseTab.hbs -->
