About Abcoulombs per cubic centimetre
The abcoulomb per cubic centimetre (abC/cm³) is the volume charge density unit of the CGS-EMU system, equal to 1 abC / 1 cm³ = 10 C / 10⁻⁶ m³ = 10⁷ C/m³. It appears in nineteenth-century electromagnetic texts and in CGS-EMU space-charge-limited current models; metallic free-electron charge densities are conveniently expressed at this scale in CGS analysis. 1 abC/cm³ = 10⁷ C/m³ = 10 MC/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.
