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.
About Coulombs per cubic yard
The coulomb per cubic yard (C/yd³) equals exactly 1/(0.9144)³ C/m³ ≈1.30795 C/m³, used in North American electrokinetic remediation projects. Electrokinetic treatment of heavy-metal contaminated soil delivers 1-10 C/yd³ of charge per treatment cycle; electro-osmosis drainage studies in US geotechnical engineering use C/yd³ as the charge dosage unit. 1 C/yd³ ≈1.308 C/m³.
