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.
About Femtocoulombs per cubic metre
The femtocoulomb per cubic metre (fC/m³) equals 10⁻¹⁵ C/m³, the scale for charge density in the interstellar medium. The diffuse interstellar medium has electron density ~3×10⁴ /m³, giving charge density ≈5 fC/m³; radiation belt proton charge density in the inner Van Allen belt is in the fC/m³ range. 1 fC/m³ = 10⁻¹⁵ C/m³ = 10⁻³ pC/m³.
