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.
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.
