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 US gallon
The coulomb per US gallon (C/gal) equals exactly 1/(231×(0.0254)³) C/m³ ≈264.172 C/m³, used in electrochemical water-treatment and flow-battery engineering in North America. Electrocoagulation systems are specified by charge dosage in C/gal (US) of treated water; flow battery electrolyte charge state is monitored in C/gal in North American plant documentation. 1 C/gal (US) ≈264.172 C/m³.
