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 Picocoulombs
The picocoulomb (pC) equals 10⁻¹² C, the standard charge unit for radiation detector pulse heights and precision electrometers. Charge signals from Geiger-Muller tubes, scintillator detectors, and proportional counters are routinely expressed in picocoulombs; a 1 pF capacitor at 1 V holds exactly 1 pC. 1 pC = 10⁻³ nC = 10³ fC.
