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 Gigacoulombs per cubic metre
The gigacoulomb per cubic metre (GC/m³) equals 10⁹ C/m³, the natural scale for free-electron charge density in metals. Copper has ~8.5×10²⁸ free electrons/m³, giving total free-charge density ≈13.6 GC/m³; gold is ≈9.4 GC/m³; this scale is also used in extreme fusion plasma models at densities above 10²⁸ /m³. 1 GC/m³ = 10⁹ C/m³ = 10³ MC/m³.
