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.
About Attocoulombs
The attocoulomb (aC) equals 10⁻¹⁸ C, sitting between the elementary charge and the femtocoulomb. It arises in ultra-sensitive charge measurements: single-electron transistors, quantum capacitance probing of graphene and 2D materials, and scanning tunnelling microscopy where tip-sample charge exchange is tracked at this scale. 1 aC = 10⁻³ fC ≈ 6.24 e.
