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 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.
