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.
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.
