1. Plural of abampere; a unit of electric current in the centimeter-gram-second (CGS) electromagnetic system, equal to 10 amperes.
Usage: technical; physics; largely historical; the ampere is the standard SI unit in modern use

Examples

• The old laboratory equipment measured current in abamperes before the adoption of SI units.
• One abampere equals ten amperes in the modern metric system.
• Physicists working with CGS units would express high currents in abamperes.
• The conversion from abamperes to amperes requires dividing by ten.
