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 inch
The coulomb per cubic inch (C/in³) equals exactly 1/(0.0254)³ C/m³ ≈61 023.7 C/m³, used in US semiconductor and battery engineering. Volumetric charge capacity of lithium-ion battery electrodes is quoted in C/in³ in North American product datasheets; solid-state electrolyte charge density specifications in US engineering standards appear in C/in³. 1 C/in³ ≈61 024 C/m³ = 61.024 kC/m³.
