Related to the Faraday constant is the "faraday", a unit of electrical charge. Its use is much less common than of the coulomb, but is sometimes used in electrochemistry. [4] One faraday of charge is the charge of one mole of elementary charges (or of negative one mole of electrons), that is, 1 faraday = F × 1 mol = 9.648 533 212 331 001 84 × ...
Faraday constant: 96 485.332 123 310 0184 ... By implication, any product of powers of such constants is also such a constant, such as the molar gas constant. See ...
For Faraday's first law, M, F, v are constants; thus, the larger the value of Q, the larger m will be. For Faraday's second law, Q, F, v are constants; thus, the larger the value of (equivalent weight), the larger m will be. In the simple case of constant-current electrolysis, Q = It, leading to
Faraday constant: coulombs per mole (C⋅mol −1) frequency: hertz (Hz) function: friction: newton (N) electrical conductance: siemens (S) universal gravitational constant: newton meter squared per kilogram squared (N⋅m 2 /kg 2) shear modulus: pascal (Pa) or newton per square meter (N/m 2)
If the Avogadro constant N A and the Faraday constant F are independently known, the value of the elementary charge can be deduced using the formula =. (In other words, the charge of one mole of electrons, divided by the number of electrons in a mole, equals the charge of a single electron.)
The term "farad" was originally coined by Latimer Clark and Charles Bright in 1861, [5] in honor of Michael Faraday, for a unit of quantity of charge, and by 1873, the farad had become a unit of capacitance. [6] In 1881, at the International Congress of Electricians in Paris, the name farad was officially used for the unit of electrical ...

The word "Faraday" in this term has two interrelated aspects: first, the historic unit for charge is the faraday (F), but has since been replaced by the coulomb (C); and secondly, the related Faraday's constant (F) correlates charge with moles of matter and electrons (amount of substance).
