Convert Coulombs to Gigacoulombs
Convert Coulombs (C) to Gigacoulombs (GC) instantly and accurately.
Conversion Formula
GC = C × 1.000000000e-9
About Coulombs
The coulomb (C) is the SI derived unit of electric charge, equal to the charge transported by a current of 1 A in 1 s. In the 2019 SI revision it is fixed exactly via the elementary charge: 1 C = 1 / (1.602 176 634 × 10⁻¹⁹) e ≈ 6.241 × 10¹⁸ e. Practical benchmarks: a 1 Ah battery stores 3 600 C; a lightning bolt transfers 1-20 C.
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.
