Circular Mil Ohm/Foot

CM·Ω/ft

Definition

A specialized unit of electric resistivity used in electrical engineering for wire and cable specifications. Combines the circular mil (area unit) with ohm per foot to express resistivity in terms of wire gauge and length.

History/Origin

Developed specifically for electrical wire and cable manufacturing in North America. The circular mil unit represents the cross-sectional area of a wire, making this unit practical for specifying wire resistivity in electrical applications.

Current Use

Extensively used in electrical wire and cable manufacturing, electrical engineering, and power distribution systems. Essential for calculating voltage drop, power loss, and conductor sizing in electrical installations.
