About Elementary charge
The elementary charge (e) is the magnitude of charge on a single proton or electron, defined exactly as 1.602 176 634 × 10⁻¹⁹ C in the 2019 SI revision. It is the quantum of electric charge - the smallest freely occurring charge in nature - and underpins all atomic and subatomic physics. A current of 1 A corresponds to 6.241 509 × 10¹⁸ elementary charges flowing per second.
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.
