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 Megacoulombs per cubic metre
The megacoulomb per cubic metre (MC/m³) equals 10⁶ C/m³, arising in degenerately doped semiconductor junctions and dense plasma physics. A degenerately doped silicon layer at 10²⁵ /m³ carries ρ ≈1.6 MC/m³; dense Z-pinch plasma cores at 10²⁵ /m³ reach MC/m³ charge densities; metallic conductor free-electron densities are GC/m³ scale. 1 MC/m³ = 10⁶ C/m³ = 10³ kC/m³.
