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.
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.
