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.
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.
