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 Kiloampere-hours
The kiloampere-hour (kAh) equals 3.6 × 10⁶ C = 3.6 MC, the practical unit for grid-scale battery storage and large industrial electrolysis. A 100 MW·h utility-scale lithium-ion installation delivers roughly 27 kAh at typical operating voltages; aluminium Hall-Heroult cells consume approximately 13 500 kAh per tonne of aluminium. 1 kAh = 10³ Ah = 3.6 MC.
