About Abcoulombs
The abcoulomb (abC) equals exactly 10 C - the charge unit of the CGS-EMU (electromagnetic) system, defined as the charge transported by 1 abampere (= 10 A) in 1 s. Two parallel wires each carrying 1 abampere and spaced 1 cm apart experience a force of 2 dyn per centimetre length. The abcoulomb appears in older electromagnetic engineering literature from the early twentieth century. 1 abC = 10 C.
About Statcoulombs
The statcoulomb (statC), also called the franklin (Fr) or ESU of charge, is the charge unit in the CGS-Gaussian system. Two point charges of 1 statC separated by 1 cm exert a force of exactly 1 dyne; 1 statC = 1 / (2.99 792 458 × 10⁹) C ≈ 3.336 × 10⁻¹⁰ C (exact, since c is a defined constant). It remains in use in electrostatics textbooks and atomic physics where working without the ε₀ factor simplifies Coulomb-law expressions.
