The unit of electric charge in the centimeter-gram-second electromagnetic system of units. Symbol, aC. One abcoulomb of charge passes a point in a circuit in one second when a 1-abampere current is flowing. One abcoulomb = 10 coulombs.

According to the current national standard in the United States¹, the abcoulomb is not to be used. The coulomb should be used instead.
