About Nanocoulombs per square metre
The nanocoulomb per square metre (nC/m²) equals 10⁻⁹ C/m², the scale for charge density on moderately charged electret films and LCD alignment-layer surfaces. Commercial cellular polypropylene electret microphones carry surface charge densities of 0.1-10 nC/m²; charge on liquid-crystal alignment layers affects pixel response times. 1 nC/m² = 10⁻⁹ C/m² = 10⁻³ µC/m².
About Coulombs per square foot
The coulomb per square foot (C/ft²) equals exactly 1/(0.3048)² C/m² ≈ 10.7639 C/m², used in North American electrostatic specifications for insulating flooring, workbench surfaces, and static-dissipative materials. ANSI/ESD standards specify electrostatic charge decay and surface charge limits in C/ft²; antistatic mat and flooring performance is rated in C/ft². 1 C/ft² ≈ 10.764 C/m².
