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.

Ohm Centimeter

Ω·cm

Definition

A metric unit of electric resistivity equal to one hundredth of an ohm meter. Commonly used for measuring the resistivity of materials in laboratory settings and industrial applications where centimeter-scale measurements are more practical.

History/Origin

Derived from the ohm meter for practical measurements in laboratory and industrial settings. The centimeter unit provides a convenient scale for measuring small samples and thin films in materials science and semiconductor research.

Current Use

Extensively used in materials science, semiconductor manufacturing, and quality control testing. Common in laboratory measurements of thin films, coatings, and small material samples where centimeter dimensions are more practical.
