About Statcoulombs per square centimetre
The statcoulomb per square centimetre (statC/cm²) is the surface charge density unit of the CGS-Gaussian system, equal to 10³/c C/m² where c = 299 792 458 m/s, giving ≈ 3.336 × 10⁻⁶ C/m². In Gaussian units Gauss's law reads E = 4πσ (no ε₀ factor); 1 statC/cm² produces a surface field of 4π statV/cm. 1 statC/cm² ≈ 3.336 µC/m².
About Coulombs per square inch
The coulomb per square inch (C/in²) equals exactly 1/(0.0254)² C/m² ≈ 1 550.003 C/m², used in US insulation and dielectric material withstand specifications. Dielectric strength ratings for polymeric films in US datasheets are sometimes cross-referenced with C/in² for high-voltage applications; electrostatic precipitator collector plate performance is quoted in C/in² in some NEMA standards. 1 C/in² ≈ 1 550 C/m².
