About Femtocoulombs per square metre
The femtocoulomb per square metre (fC/m²) equals 10⁻¹⁵ C/m², arising in scanning Kelvin probe measurements of oxide fixed charge. MOS interface state densities of 10¹ charges/cm² correspond to about 0.16 fC/m²; fixed charge in high-k gate dielectrics and SiO₂/Si interfaces is typically 10-100 fC/m². 1 fC/m² = 10⁻¹⁵ C/m² = 10⁻³ pC/m².
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.
