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.
About Picocoulombs per cubic metre
The picocoulomb per cubic metre (pC/m³) equals 10⁻¹² C/m³, the scale for solar wind charge density and fair-weather atmospheric electricity. The solar wind near Earth has electron density ~5×10⁶ /m³, giving charge density ≈0.8 pC/m³; fair-weather atmospheric space charge near sea level is 1-10 pC/m³. 1 pC/m³ = 10⁻¹² C/m³ = 10⁻³ nC/m³.
