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.
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.
