The volt (symbol: V) is the SI unit of electric potential (voltage). It is defined as the potential difference that drives a current of one ampere through a resistance of one ohm, or equivalently, one joule of energy per coulomb of charge. Named after Alessandro Volta.
Abvolt
The abvolt (symbol: abV) is the CGS-EMU unit of electric potential. One abvolt equals 10⁻⁸ volts (10 nanovolts). It is used in electromagnetic CGS unit systems.
