GC/m² = pC/m² × 1.000000000e-21
About Picocoulombs per square metre
The picocoulomb per square metre (pC/m²) equals 10⁻¹² C/m², the scale for surface charge density on lightly charged polymer electret films and semiconductor surface states. Low-dose ion-implanted silicon has surface charge densities of 1-100 pC/m²; piezoelectric polymer films (PVDF) accumulate picocoulombs per square metre at low mechanical stress. 1 pC/m² = 10⁻¹² C/m² = 10⁻³ nC/m².
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.
