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 Ampere-hours
The ampere-hour (Ah) equals exactly 3 600 C and is the universal capacity unit for rechargeable batteries. Lead-acid car batteries are rated 40-100 Ah; EV traction packs use 50-300 Ah cells; industrial forklift batteries exceed 1 000 Ah. Multiplying Ah by nominal voltage gives watt-hours of stored energy. 1 Ah = 3 600 C = 1 000 mAh.
