Usage
Select the wire gauge and then select the data column you wish to see.
Applications
This equation can be used to simply look-up the characteristic diameter of a standard gauge wire or the ampacity of a wire for use in a home project. This equation as a lookup might also be used as an equation-in-equation (EiE) for other equations requiring data from this table. For instance, you could create an equation for a home building calculator that inputs length of a wire run and computed total voltage loss. By simply dragging and dropping this AWG Lookup equation into the Groovy code for the voltage loss calculation, you could make voltage loss calculable for all standard wire gauges.
Description
The AWG is also known as the Brown and Sharpe wire gauge and has been used since 1857 in North America, so this standard predominates over any other wire specification in practical use.
By definition, No. 36 AWG is 0.005 inches in diameter, and No. 0000 is 0.46 inches in diameter. The ratio of these diameters is 1:92, and there are 40 gauge sizes from No. 36 to No. 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 ![\sqrt [39]{92}](https://www.vcalc.com/attachments/cab3d51c-f074-11e3-b7aa-bc764e2038f2/fd0576bc7a7c22e7f482efa1de034f92.png)
(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
