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 Attocoulombs per cubic metre
The attocoulomb per cubic metre (aC/m³) equals 10⁻¹⁸ C/m³, a scale with fewer than 10 elementary charges per cubic metre. Residual charge density in the intergalactic medium (~0.1 ion/m³) is around 0.016 aC/m³; theoretical models of charge density in near-vacuum regions and cosmological large-scale structure simulations use aC/m³. 1 aC/m³ = 10⁻¹⁸ C/m³ = 10⁻³ fC/m³.
