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 Millicoulombs per square metre
The millicoulomb per square metre (mC/m²) equals 10⁻³ C/m², the scale for triboelectric charging of common plastics and electrostatic spray-coating processes. Rubbed polytetrafluoroethylene (PTFE) accumulates 1-10 mC/m²; electrostatic powder coating guns deposit 1-5 mC/m² on grounded work pieces; thundercloud base charge density before lightning is 1-5 mC/m². 1 mC/m² = 10⁻³ C/m² = 10³ µC/m².
