Convert Coulombs per US gallon to Gigacoulombs per cubic metre
Convert Coulombs per US gallon (C/gal (US)) to Gigacoulombs per cubic metre (GC/m³) instantly and accurately.
Conversion Formula
GC/m³ = C/gal (US) × 2.641720524e-7
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.
About Gigacoulombs per cubic metre
The gigacoulomb per cubic metre (GC/m³) equals 10⁹ C/m³, the natural scale for free-electron charge density in metals. Copper has ~8.5×10²⁸ free electrons/m³, giving total free-charge density ≈13.6 GC/m³; gold is ≈9.4 GC/m³; this scale is also used in extreme fusion plasma models at densities above 10²⁸ /m³. 1 GC/m³ = 10⁹ C/m³ = 10³ MC/m³.
