About Coulombs per cubic metre
The coulomb per cubic metre (C/m³) is the SI coherent unit of volume charge density, equal to 1 A·s·m⁻³. The depletion region of a silicon pn junction doped at ~6×10¹⁸ /m³ carries ρ ≈1 C/m³; the lightning return-stroke channel has net charge density of several C/m³; electrolytic capacitor dielectric space charge is in the C/m³ range. 1 C/m³ = 10³ mC/m³.
About Gigacoulombs per cubic metre
The gigacoulomb per cubic metre (GC/m³) equals 10⁹ C/m³, the natural scale for free-electron charge density in metals. Copper has ~8.5×10²⁸ free electrons/m³, giving total free-charge density ≈13.6 GC/m³; gold is ≈9.4 GC/m³; this scale is also used in extreme fusion plasma models at densities above 10²⁸ /m³. 1 GC/m³ = 10⁹ C/m³ = 10³ MC/m³.
