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 Millicoulombs
The millicoulomb (mC) equals 10⁻³ C, encountered in electroplating thin films, faradaic charge integration in voltammetry, and capacitor discharge testing. Cyclic voltammetry integration of an electrode adsorption peak typically yields 1-100 mC; a 1 mF supercapacitor at 1 V stores exactly 1 mC. 1 mC = 10⁻³ C = 10³ µC.
