When the cross-sectional area of a wire is doubled, the AWG will decrease by 3. (E.g. two 14 AWG wires have about the same cross-sectional area as a single 11 AWG wire.) This doubles the conductance. When the diameter of a solid round wire is doubled, the AWG will decrease by 6. (E.g. 1 mm diameter wire is ≈18 AWG, 2 mm diameter wire is ≈12 ...
IEC 60228, the metric wire-size standard used in most parts of the world. Circular mil, Electrical industry standard for wires larger than 4/0. American Wire Gauge (AWG), used primarily in the US and Canada; Standard Wire Gauge (SWG), the British imperial standard BS3737; Jewelry wire gauge; Body jewelry sizes
Comparison of SWG (red), AWG (blue) and IEC 60228 (black) wire gauge sizes from 0.03 to 200 mm² to scale on a 1 mm grid – in the SVG file, hover over a size to highlight it. In engineering applications, it is often most convenient to describe a wire in terms of its cross-section area, rather than its diameter, because the cross section is directly proportional to its strength and weight ...
For example, one common wire size used in the NEC has a conductor diameter of 0.5 inches, or 500 mils, and thus a cross-section of = circular mils, written as 250 kcmil or 250 MCM, which is the first size larger than 0000 AWG used within the NEC.

Litz wire is used for the helix and variometer in both helix houses. It consists of 9 × 5 × 5 × 27 (totaling 6,075) strands of #36 AWG (0.127 mm [0.0050 in] diameter) magnet wire and multiple layers of cotton, hemp, and plastic insulation, in a cable 19 mm (3 ⁄ 4 inch) in diameter, totaling 151,875 circular mils (0.7695619839 cm 2) of ...
A standard wire gauge. The British Standard Wire Gauge, often referred to as the Standard Wire Gauge or simply SWG, is a unit used to denote wire gauge (size) as defined by BS 3737:1964, a standard that has since been withdrawn. It is also known as the Imperial Wire Gauge or British Standard Gauge. Although its use has significantly declined ...
Sample cross-section of high tension power (pylon) line, showing 1 strand (7 wires) of steel surrounded by 4 concentric layers of aluminium. Aluminum conductor steel-reinforced cable (ACSR) is a type of high-capacity, high-strength stranded conductor typically used in overhead power lines.
