1. A unit of electric current in the centimeter-gram-second (CGS) electromagnetic system, equal to 10 amperes.
Usage: technical; physics; largely obsolete; replaced by the ampere in modern SI units

Examples

• The abamp was once used in electromagnetic measurements before the adoption of SI units.
• One abamp equals exactly 10 amperes in the modern metric system.
• Early physics textbooks often expressed current in abamps when working with CGS units.
• The conversion from abamps to amperes is straightforward: divide by 10.
