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 Abcoulombs per square centimetre
The abcoulomb per square centimetre (abC/cm²) is the surface charge density unit of the CGS-EMU system, equal to 1 abC / 1 cm² = 10 C / 10⁻⁴ m² = 10⁵ C/m². It appears in nineteenth-century electromagnetic engineering texts on telegraph cable and dynamo analysis; the abC/cm² is the natural surface density unit when using abamperes and centimetres. 1 abC/cm² = 10⁵ C/m² = 100 kC/m².
