Unit abΩ
Name abohm
Category Electrical Resistance
Details The abohm (abΩ) is a unit of electrical resistance in the centimeter-gram-second (cgs) electromagnetic system of units, which is a part of the Gaussian unit system. It is a non-SI unit of measurement that was mainly used in scientific and engineering works before the adoption of the International System of Units (SI).

One abohm represents the resistance of a conductor through which a current of one abampere (the cgs unit of current) flows, producing a potential difference of one abvolt (the cgs unit of electric potential) across the conductor.

The conversion of abohm to the modern SI unit, ohm (Ω), is as follows:

1 abohm = 1 x 10⁻⁹ ohm

It means that one abohm is equivalent to one-billionth (0.000000001) of one ohm.

AbΩ is not commonly used today, and electrical resistance is typically measured in ohms, which is the SI unit.
