About Gigacoulombs per square metre
The gigacoulomb per square metre (GC/m²) equals 10⁹ C/m², a value with no engineering realisation, used only in astrophysical and theoretical plasma models. Magnetar magnetosphere charge sheet densities, pulsar polar cap surface charge, and theoretical cosmic string surface charge are described at GC/m² scales in research literature. 1 GC/m² = 10⁹ C/m² = 10³ MC/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.
