Conversion Formula
pC = GC × 1.000000000e+21
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 Picocoulombs
The picocoulomb (pC) equals 10⁻¹² C, the standard charge unit for radiation detector pulse heights and precision electrometers. Charge signals from Geiger-Muller tubes, scintillator detectors, and proportional counters are routinely expressed in picocoulombs; a 1 pF capacitor at 1 V holds exactly 1 pC. 1 pC = 10⁻³ nC = 10³ fC.
