A unit of electric charge in the CGS (centimeter-gram-second) system, equal to one-tenth of a coulomb, now mostly replaced by the coulomb in SI units.
From 'ab-' (short for 'abampere,' the CGS unit of current) + 'coulomb' (named after physicist Charles-Augustin de Coulomb). This is a legacy unit from the older CGS system.
The 'abcoulomb' is a ghost of physics history—it's the unit that scientists used before they agreed on SI units in 1960, making it a measuring word that's almost completely extinct in modern physics, like a dodo bird of measurement.
