About Femtocoulombs
The femtocoulomb (fC) equals 10⁻¹⁵ C, used in radiation detection, MEMS sensors, and microelectronics charge characterisation. A single ionising particle traversing a thin silicon strip detector typically deposits 1-80 fC; noise floors of charge-sensitive amplifiers in nuclear instrumentation are specified in femtocoulombs. 1 fC = 10⁻³ pC = 10³ aC.
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.
