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.
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.
