About Coulombs per square centimetre
The coulomb per square centimetre (C/cm²) equals exactly 10⁴ C/m², used in electrochemistry for Faradaic charge densities in electrolytic cells and battery electrode characterisation. The theoretical charge density for lithiation of a graphene anode monolayer is ≈ 0.38 C/cm²; proton exchange membrane fuel cell charge densities are 0.1-1 C/cm²; pulsed-laser ablation craters carry µC to mC per cm². 1 C/cm² = 10⁴ C/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.
