'''American wire gauge''' ('''AWG'''), also known as the '''[[Brown & Sharpe]] wire gauge''', is a [[Standardization|standardized]] [[wire gauge]] system used since 1857 predominantly in the United States and Canada for the diameters of round, solid, nonferrous, [[Electricity|electrically]] [[Electrical conduction|conducting]] wire.<ref><abbr title="American Society for Testing And Materials">ASTM</abbr> Standard B 258-02, ''Standard specification for standard nominal diameters and cross-sectional areas of AWG sizes of solid round wires used as electrical conductors'', [[ASTM]] International, 2002</ref>  The cross-sectional area of each gauge is  an important factor for determining its [[ampacity|current-carrying capacity]].
 
The steel industry does not use AWG and prefers a number of other wire gauges.{{citation needed|date=January 2013}}  These include [[Ichabod Washburn|Washburn]] & Moen (or W&M) Wire Gauge, [[U.S. Steel|US Steel]] Wire Gauge, and Music Wire Gauge (see [[Piano wire]]).
 
Increasing gauge numbers give decreasing wire diameters, which is similar to many other non-[[SI|metric]] gauging systems. This gauge system originated in the number of [[Wire drawing|drawing operations]] used to produce a given gauge of wire. Very fine wire (for example, 30&nbsp;gauge) required more passes through the [[Draw plate|drawing dies]] than did 0&nbsp;gauge wire. Manufacturers of wire formerly had proprietary wire gauge systems; the development of standardized wire gauges rationalized selection of wire for a particular purpose.
 
The AWG tables are for a single, solid, round conductor. The AWG of a stranded wire is determined by the total cross-sectional area of the conductor, which determines its current-carrying capacity and [[electrical resistance]].  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.
 
{{anchor|body_jewelry}}AWG is also commonly used to specify [[Body jewelry sizes|body piercing jewelry sizes]] (especially smaller sizes), even when the material is not metallic.<ref>[http://www.steelnavel.com/reference.asp SteelNavel.com Body Piercing Jewelry Size Reference — illustrating the different ways that size is measured on different kinds of jewelry]</ref> However, metallic [[hypodermic needle]]s and blunt needles are usually specified in terms of [[Needle gauge comparison chart|Needle gauge]].
 
==Formula==
By definition, No.&nbsp;36&nbsp;AWG is 0.005&nbsp;inches in diameter, and No.&nbsp;0000 is 0.46&nbsp;inches in diameter. The ratio of these diameters is 1:92, and there are 40 gauge sizes from No.&nbsp;36 to No.&nbsp;0000, or 39 steps. Because each successive gauge number increases diameter by a constant multiple, diameters vary geometrically.  Any two successive gauges (e.g. A & B ) have diameters in the ratio (dia. B ÷ dia. A) of <math>\sqrt [39]{92}</math> (approximately 1.12293), while for  gauges two steps apart (e.g. A, B & C), the ratio of the C to A is about 1.12293² = 1.26098.  The diameter of a No.&nbsp;''n''&nbsp;AWG wire is determined, for gauges smaller than 00 (36 to 0), according to the following formula:
:<math>d_n = 0.005~\mathrm{inch} \times 92 ^ \frac{36-n}{39} = 0.127~\mathrm{mm} \times 92 ^ \frac{36-n}{39}</math>
<small>(see below for gauges larger than No. 0 (i.e. No. 00, No. 000, No. 0000 ).)</small>
or equivalently
:<math>d_n = e^ {-1.12436 - 0.11594n}\ \mathrm{inch} = e^ {2.1104 - 0.11594n}\ \mathrm{mm} </math>
The gauge can be calculated from the diameter using
:<math>n = -39\log_{92} \left( \frac{d_{n}}{0.005~\mathrm{inch}} \right)+36 = -39\log_{92} \left( \frac{d_{n}}{0.127~\mathrm{mm}} \right)+36</math>  <ref>The logarithm to the base 92 can be computed using any other logarithm, such as [[Common logarithm|common]] or [[natural logarithm]], using log<sub>92</sub>''x'' = (log ''x'')/(log 92).</ref>
and the cross-section area is
:<math>A_n = \frac{\pi}{4} d_n^2 = 0.000019635~\mathrm{inch}^2 \times 92 ^ \frac{36-n}{19.5} = 0.012668~\mathrm{mm}^2 \times 92 ^ \frac{36-n}{19.5}</math>,
The standard '''ASTM B258 - 02(2008) ''Standard Specification for Standard Nominal Diameters and Cross-Sectional Areas of AWG Sizes of Solid Round Wires Used as Electrical Conductors''''' defines the ratio between successive sizes to be the 39th root of 92, or approximately 1.1229322.<ref>ASTM Standard B 258-02, page 4</ref> ASTM B 258-02 also dictates that wire diameters should be tabulated with no more than 4 significant figures, with a resolution of no more than 0.0001&nbsp;inches (0.1 mils) for wires larger than No. 44 AWG, and 0.00001&nbsp;inches (0.01 mils) for wires No. 45 AWG and smaller.
Sizes with multiple zeros are successively larger than No.&nbsp;0 and can be denoted using "''number of zeros''/0", for example 4/0 for 0000.  For an ''m''/0 AWG wire, use ''n'' = &minus;(''m''&minus;1) = 1&minus;''m'' in the above formulas. For instance, for No. 0000 or 4/0, use n = −3.
 
===Rules of thumb===
The sixth power of this ratio is very close to 2,<ref>The result is roughly 2.0050, or one-quarter of one percent higher than 2</ref> which leads to the following rules of thumb:
*When the ''diameter'' of a wire is doubled, the AWG will decrease by 6. (e.g., No.&nbsp;2 AWG is about twice the diameter of No.&nbsp;8 AWG.)
*When the ''[[Cross section (geometry)|cross-sectional]] area'' of a wire is doubled, the AWG will decrease by 3. (e.g., Two No.&nbsp;14 AWG wires have about the same cross-sectional area as a single No.&nbsp;11 AWG wire.)
Additionally, a decrease of ten gauge numbers, for example from No.&nbsp;10 to 1/0, multiplies the area and weight by approximately 10 and reduces the resistance by a factor of approximately 10.
[[Aluminum wire]] has a conductivity of approximately 61% of copper, so an aluminum wire has almost the same resistance as a [[copper wire]] 2 AWG smaller.  (Which has 62.9% of the area.)
 
==Tables of AWG wire sizes==
 
The table below shows various data including both the resistance of the various wire gauges and the allowable current ([[ampacity]]) based on plastic insulation. The diameter information in the table applies to ''solid'' wires. [[Stranded wire]]s are calculated by calculating the equivalent [[cross section (geometry)|cross sectional]] [[Copper wire and cable|copper]] [[area]]. Fusing current (melting wire) is estimated based on 25[[°C]] ambient temperature. The table below assumes [[Direct current|DC]], or [[Alternating Current|AC]] frequencies equal to or less than 60&nbsp;Hz, and does not take [[skin effect]] into account.  Turns of wire is an upper limit for wire with no insulation.

In the North American electrical industry, conductors larger than 4/0 AWG are generally identified by the area in thousands of [[circular mil]]s ('''kcmil'''), where 1&nbsp;kcmil = 0.5067&nbsp;mm². The next wire size larger than 4/0 has a cross section of 250 kcmil. A ''circular mil'' is the area of a wire one [[Thou (unit of length)|mil]] in diameter. One million circular mils is the area of a circle with 1000&nbsp;mil = 1&nbsp;inch diameter. An older abbreviation for one thousand circular mils is ''MCM''.
 
== Stranded wire AWG sizes ==
 
AWG gauges are also used to describe stranded wire.  In this case, it describes a wire which is equal in cross-sectional area to the total of all the cross-sectional areas of the individual strands; the gaps between strands are not counted.  When made with circular strands (see [[Circle packing]]), these gaps occupy about 10% of the wire area, thus requiring a wire about 5% thicker than equivalent solid wire.
 
Stranded wires are specified with three numbers, the overall AWG size, the number of strands, and the AWG size of a strand. The number of strands and the AWG of a strand are separated by a slash. For example, a 22 AWG 7/30 stranded wire is a 22 AWG wire made from seven strands of 30 AWG wire.
 
==Nomenclature and abbreviations in electrical distribution==
{{main|Electric power distribution}}
Alternate ways are commonly used in the electrical industry to specify wire sizes as AWG.
*'''4 AWG'''  (proper)
**'''#4''' (the [[number sign]] is used as an abbreviation for "number")
**'''No. 4''' ([[Numero sign|No.]] is used as an abbreviation for "number")
**'''No. 4 AWG'''
**'''4 ga.''' (abbreviation for "gauge")
*'''000 AWG''' (proper for large sizes) 
**'''3/0''' (common for large sizes)  Pronounced 3 aught
**'''3/0 AWG'''
**'''#000'''
**'''#3/0'''
 
The industry also bundles [[Electrical wiring|common wire]] for use in [[electric power distribution]] in homes and businesses, identifying a bundle's wire size followed by the number of wires in the bundle. The most common type of distribution cable, NM-B, is generally implied:
* #14/'''2''' (also written "14-2") is a nonmetallic sheathed bundle of ''two'' solid 14 AWG wires. The insulation surrounding the two conductors is white and black. This sheath for 14 AWG cable is usually white when used for NM-B wiring intended for electrical distribution in a dry location. Newly manufactured cables without a separate ground wire (such as #14/2) are [[obsolete]].
* #12/'''2''' '''''with ground''''' (also written "12-2 w/gnd") is a nonmetallic sheathed bundle of ''three'' solid 12 AWG wires having a bare ground in the middle of '''two''' insulated conductors in a flat-shaped NM-B yellow-colored sheath. The color is a North American industry standard for cables made since 2003, and aids identification.
* #10/'''3''' '''''with ground''''' (also written "10-3 w/gnd") is a nonmetallic sheathed bundle of ''four'' solid 10 AWG wires having a bare ground and '''three''' insulated conductors twisted into a round-shaped NM-B orange-colored sheath. The insulated conductors are black, white, and red. Some cable of this type may be flat to save copper.
 
==Pronunciation==
''AWG'' is colloquially referred to as ''gauge'' and the zeros in large wire sizes are referred to as ''[[aught]]'' {{IPAc-en|ˈ|ɔː|t}}. Wire sized 1 AWG is referred to as "one gauge" or "No. 1" wire; similarly, smaller diameters are pronounced "''x'' gauge" or "No. X" wire, where ''x'' is the positive integer AWG number.  Consecutive AWG wire sizes larger than No. 1 wire are designated by the number of zeros:
*No. 0, typically written 1/0 and is referred to as 1 "aught" wire
*No. 00, typically written 2/0 and is referred to as 2 "aught" wire
*No. 000, typically written 3/0 and is referred to as 3 "aught" wire,
and so on.
