About Megacoulombs

The megacoulomb (MC) equals 10⁶ C ≈ 277.8 Ah, relevant to large-scale energy storage and high-current industrial electrochemical processes. A 1 MW·h lithium-ion storage system holds roughly 1-1.5 GC total charge depending on cell voltage; aluminium electrolysis cells process tens of megacoulombs per day per cell. 1 MC = 10⁻³ GC = 10³ kC.

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.
