About Megacoulombs
The megacoulomb (MC) equals 10⁶ C ≈ 277.8 Ah, relevant to large-scale energy storage and high-current industrial electrochemical processes. A 1 MW·h lithium-ion storage system holds roughly 1-1.5 GC total charge depending on cell voltage; aluminium electrolysis cells process tens of megacoulombs per day per cell. 1 MC = 10⁻³ GC = 10³ kC.
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.
