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 metre
The coulomb per square metre (C/m²) is the SI coherent unit of surface charge density, equal to 1 A·s·m⁻². A parallel-plate capacitor with 1 C/m² on each plate produces a gap field of 1/ε₀ ≈ 113 GV/m; realistic capacitor plate densities are 10-100 µC/m²; charge density on a sphere at electrical breakdown of air is about 27 µC/m². 1 C/m² = 10³ mC/m² = 10⁶ µC/m².
