abohm

The unit of electric resistance in the centimeter-gram-second electromagnetic system of units. A conductor has a resistance of 1 abohm when the potential difference between the two ends of the conductor is 1 abvolt when a current of 1 abampere flows through it. Symbol, abΩ. One abohm = 10^-9 ohm.

According to the current national standard in the United States¹, the abohm is not to be used. The ohm should be used instead.
