Convert Picocoulombs per cubic metre (pC/m³) to Coulombs per US gallon (C/gal (US)) instantly and accurately.
Conversion Formula
C/gal (US) = pC/m³ × 3.785411784e-15
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.
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.
