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 Faradays
The faraday (F) equals the Avogadro constant times the elementary charge - N_A × e ≈ 96 485.33 C per mole - and is the fundamental unit of electrochemical charge (Faraday's law: 1 F deposits one gram-equivalent of any substance). Depositing 1 g of silver (Ag⁺, M = 107.87 g/mol) requires 96 485 / 107.87 ≈ 894 C ≈ 0.00927 F; plating copper (Cu²⁺) requires 2 F per mole. 1 F ≈ 26.801 Ah ≈ 96.485 kC.
