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 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.
