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 Kilocoulombs
The kilocoulomb (kC) equals 10³ C ≈ 0.278 Ah, used in industrial electrochemistry, large capacitor bank energy calculations, and fault current analysis. Electroplating a 100 cm² nickel layer 25 µm thick requires roughly 2-4 kC; power-factor-correction capacitor banks in substations may store several kilocoulombs. 1 kC = 10⁻³ MC = 10³ C.
