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 Kiloampere-hours
The kiloampere-hour (kAh) equals 3.6 × 10⁶ C = 3.6 MC, the practical unit for grid-scale battery storage and large industrial electrolysis. A 100 MW·h utility-scale lithium-ion installation delivers roughly 27 kAh at typical operating voltages; aluminium Hall-Heroult cells consume approximately 13 500 kAh per tonne of aluminium. 1 kAh = 10³ Ah = 3.6 MC.
