Mho

℧

Definition

An older unit of electric conductance equal to one siemens, representing the inverse of resistance. The name "mho" is "ohm" spelled backwards, reflecting its relationship to resistance.

History/Origin

Created as the inverse of the ohm unit for measuring electrical conductance. The name "mho" (ohm spelled backwards) was used before the adoption of the siemens as the official SI unit of conductance.

Current Use

Still used in some electrical engineering contexts and older technical literature. Gradually being replaced by the siemens unit in modern electrical engineering practice and international standards.

Abmho

ab℧

Definition

A very large unit of electric conductance in the CGS electromagnetic system equal to one billion siemens. Used for measuring extremely high conductance values in specialized electrical applications.

History/Origin

Part of the CGS electromagnetic system of units, where "ab" stands for "absolute." The abmho was used in early electrical measurements before the adoption of the SI system for very high conductance values.

Current Use

Used in specialized scientific research and some technical applications for measuring extremely high conductance values. Still referenced in some physics and electrical engineering literature.
