noun
- A unit of electric charge in the centimeter-gram-second (CGS) electromagnetic system, equal to one tenth of a coulomb.
Usage: physics; technical; largely superseded by the SI coulomb in modern usage
Examples
- The abcoulomb was commonly used in older physics textbooks before the adoption of SI units.
- In CGS units, charge is measured in abcoulombs rather than coulombs.
- The conversion factor between abcoulombs and coulombs is 0.1.
- Historical physics experiments often reported charge measurements in abcoulombs.
