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 Picocoulombs per square metre
The picocoulomb per square metre (pC/m²) equals 10⁻¹² C/m², the scale for surface charge density on lightly charged polymer electret films and semiconductor surface states. Low-dose ion-implanted silicon has surface charge densities of 1-100 pC/m²; piezoelectric polymer films (PVDF) accumulate picocoulombs per square metre at low mechanical stress. 1 pC/m² = 10⁻¹² C/m² = 10⁻³ nC/m².
