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.
About Femtocoulombs
The femtocoulomb (fC) equals 10⁻¹⁵ C, used in radiation detection, MEMS sensors, and microelectronics charge characterisation. A single ionising particle traversing a thin silicon strip detector typically deposits 1-80 fC; noise floors of charge-sensitive amplifiers in nuclear instrumentation are specified in femtocoulombs. 1 fC = 10⁻³ pC = 10³ aC.
