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 Attocoulombs per square metre
The attocoulomb per square metre (aC/m²) equals 10⁻¹⁸ C/m², the scale for areal charge density on individual molecular monolayers measured by Kelvin probe force microscopy. A single elementary charge on a 1 µm² area gives about 0.16 aC/m²; contact potential distributions in organic photovoltaic blends correspond to aC/m²-scale surface charge. 1 aC/m² = 10⁻¹⁸ C/m² = 10⁻³ fC/m².
