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 Millicoulombs per square metre

The millicoulomb per square metre (mC/m²) equals 10⁻³ C/m², the scale for triboelectric charging of common plastics and electrostatic spray-coating processes. Rubbed polytetrafluoroethylene (PTFE) accumulates 1-10 mC/m²; electrostatic powder coating guns deposit 1-5 mC/m² on grounded work pieces; thundercloud base charge density before lightning is 1-5 mC/m². 1 mC/m² = 10⁻³ C/m² = 10³ µC/m².
