About Coulombs per cubic metre
The coulomb per cubic metre (C/m³) is the SI coherent unit of volume charge density, equal to 1 A·s·m⁻³. The depletion region of a silicon pn junction doped at ~6×10¹⁸ /m³ carries ρ ≈1 C/m³; the lightning return-stroke channel has net charge density of several C/m³; electrolytic capacitor dielectric space charge is in the C/m³ range. 1 C/m³ = 10³ mC/m³.
About Coulombs per US gallon
The coulomb per US gallon (C/gal) equals exactly 1/(231×(0.0254)³) C/m³ ≈264.172 C/m³, used in electrochemical water-treatment and flow-battery engineering in North America. Electrocoagulation systems are specified by charge dosage in C/gal (US) of treated water; flow battery electrolyte charge state is monitored in C/gal in North American plant documentation. 1 C/gal (US) ≈264.172 C/m³.
