The abvolt is one option for the unit of potential difference in the EMU-CGS system of units, and is equal to 10−8 volts in the SI system.

A potential difference of 1 abV will drive a current of one abampere through a resistance of one abohm.

In most practical applications, the volt and its multiples are preferred. The national standard in the United States [1] deprecates the use of the abvolt, suggesting the use of volts instead.

The other option in the cgs system is the statvolt.
