About Coulombs per square metre
The coulomb per square metre (C/m²) is the SI coherent unit of surface charge density, equal to 1 A·s·m⁻². A parallel-plate capacitor with 1 C/m² on each plate produces a gap field of 1/ε₀ ≈ 113 GV/m; realistic capacitor plate densities are 10-100 µC/m²; charge density on a sphere at electrical breakdown of air is about 27 µC/m². 1 C/m² = 10³ mC/m² = 10⁶ µC/m².
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.
