About Elementary charge
The elementary charge (e) is the magnitude of charge on a single proton or electron, defined exactly as 1.602 176 634 × 10⁻¹⁹ C in the 2019 SI revision. It is the quantum of electric charge - the smallest freely occurring charge in nature - and underpins all atomic and subatomic physics. A current of 1 A corresponds to 6.241 509 × 10¹⁸ elementary charges flowing per second.
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.
