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 Picocoulombs per cubic metre
The picocoulomb per cubic metre (pC/m³) equals 10⁻¹² C/m³, the scale for solar wind charge density and fair-weather atmospheric electricity. The solar wind near Earth has electron density ~5×10⁶ /m³, giving charge density ≈0.8 pC/m³; fair-weather atmospheric space charge near sea level is 1-10 pC/m³. 1 pC/m³ = 10⁻¹² C/m³ = 10⁻³ nC/m³.
