About Kilocoulombs per square metre
The kilocoulomb per square metre (kC/m²) equals 10³ C/m², the scale for electrochemical processes involving heavy plating, electrolytic metal dissolution, and pulsed-power surface ablation. Thick copper electroforming runs accumulate kC/m²-scale charge; electrochemical machining (ECM) removes material at multi-kC/m² charge densities; large electrolytic capacitor anode foils are etched at kC/m². 1 kC/m² = 10³ C/m².
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.
