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.

Abohm Centimeter
abΩ·cm
Definition
An extremely small unit of electric resistivity in the CGS electromagnetic system equal to 1.0E-11 ohm meters. Used for measuring ultra-low resistivity materials in specialized scientific and engineering applications.
History/Origin
Part of the CGS electromagnetic system of units, where "ab" stands for "absolute." The abohm centimeter was used in early electrical measurements before the adoption of the SI system for precise resistivity characterization.
Current Use
Used in specialized scientific research, particularly in physics and materials science for measuring ultra-low resistivity materials. Still referenced in some technical literature and historical measurements.
