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.

About Millicoulombs per square centimetre

The millicoulomb per square centimetre (mC/cm²) equals exactly 10 C/m², used in electrochemical plating and electrophoretic deposition. Electrodeposition of copper at 10 C/m² deposits a monolayer-scale film; faradaic charge density in electrochemical supercapacitors is 1-100 mC/cm²; silver electroplating baths run at 2-10 mC/cm² for thin coatings. 1 mC/cm² = 10 C/m².
