F Standard Specification for Driven Fasteners: A circular mil is the area of a wire one mil in diameter. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. This specification prescribes the standard nominal diameters and cross-sectional areas of American Wire Gage AWG sizes of solid round wires, used as electrical conductors, and gives equations and rules for the calculation of standard nominal mass and lengths, resistances, and breaking or rated strengths of such wires.

Sizes with multiple zeros are successively larger than No. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Each system shall be used independently of the other. AWG gauges are also used to describe stranded wire. Turns of wire is an upper limit for wire with no insulation. The AWG of a stranded wire is determined by the cross-sectional area of the equivalent solid conductor.
