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 Attocoulombs per cubic metre
The attocoulomb per cubic metre (aC/m³) equals 10⁻¹⁸ C/m³, a scale with fewer than 10 elementary charges per cubic metre. Residual charge density in the intergalactic medium (~0.1 ion/m³) is around 0.016 aC/m³; theoretical models of charge density in near-vacuum regions and cosmological large-scale structure simulations use aC/m³. 1 aC/m³ = 10⁻¹⁸ C/m³ = 10⁻³ fC/m³.
