Attocoulombs (aC)
Gigacoulombs (GC)

Conversion Formula

GC = aC × 1.000000000e-27

About Attocoulombs

The attocoulomb (aC) equals 10⁻¹⁸ C, sitting between the elementary charge and the femtocoulomb. It arises in ultra-sensitive charge measurements: single-electron transistors, quantum capacitance probing of graphene and 2D materials, and scanning tunnelling microscopy where tip-sample charge exchange is tracked at this scale. 1 aC = 10⁻³ fC ≈ 6.24 e.

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.
