1. A unit of electrical potential difference in the centimeter-gram-second (CGS) system, equal to one billionth of a volt.
Usage: technical; physics; rarely used in modern practice; the volt is the standard SI unit

Examples

• The abvolt is part of the CGS electromagnetic unit system.
• One abvolt equals 10⁻⁸ volts in the SI system.
• Modern electrical measurements use the volt rather than the abvolt.
• The abvolt was historically used in some physics calculations before SI standardization.
