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 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.
