Conversion Formula
GC = Ah × 3.600000000e-6
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.
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.
