Convert Millicoulombs (mC) to Gigacoulombs (GC) instantly and accurately.

Millicoulombs (mC)
Gigacoulombs (GC)

Conversion Formula

GC = mC × 1.000000000e-12

About Millicoulombs

The millicoulomb (mC) equals 10⁻³ C, encountered in electroplating thin films, faradaic charge integration in voltammetry, and capacitor discharge testing. Cyclic voltammetry integration of an electrode adsorption peak typically yields 1-100 mC; a 1 mF supercapacitor at 1 V stores exactly 1 mC. 1 mC = 10⁻³ C = 10³ µC.

About Gigacoulombs

The gigacoulomb (GC) equals 10⁹ C ≈ 277 778 Ah, representing charge at the scale of global atmospheric electricity or very large-scale industrial electrolysis installations. Earth's global electric circuit maintains an atmospheric charge of the order of a few GC; a 1 GW·h grid-scale energy storage facility holds of order 1-10 GC depending on voltage. 1 GC = 10⁻³ TC = 10³ MC.
