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 cubic inch
The coulomb per cubic inch (C/in³) equals exactly 1/(0.0254)³ C/m³ ≈61 023.7 C/m³, used in US semiconductor and battery engineering. Volumetric charge capacity of lithium-ion battery electrodes is quoted in C/in³ in North American product datasheets; solid-state electrolyte charge density specifications in US engineering standards appear in C/in³. 1 C/in³ ≈61 024 C/m³ = 61.024 kC/m³.
