About Coulombs per cubic foot

The coulomb per cubic foot (C/ft³) equals exactly 1/(0.3048)³ C/m³ ≈35.3147 C/m³, used in North American materials testing and industrial electrostatics standards. Electrostatic charge density in polymer foam packaging is quoted in C/ft³ in ASTM standards; ESD-protective bag and tray charge retention is rated in C/ft³ in US industrial specifications. 1 C/ft³ ≈35.315 C/m³.

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.
