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 Nanocoulombs per cubic metre
The nanocoulomb per cubic metre (nC/m³) equals 10⁻⁹ C/m³, the scale for thundercloud volume charge and laboratory low-pressure plasmas. The main negative charge region of a mature thunderstorm has volume charge density of 1-5 nC/m³; glow discharge plasma at ~1 Pa has space charge density in the nC/m³ to µC/m³ range. 1 nC/m³ = 10⁻⁹ C/m³ = 10⁻³ µC/m³.
