In physics, the faraday (not to be confused with the farad) is a dimensionless unit of electrical charge; one faraday is equal to the charge of 6.02 × 10²³ electrons (one mol). The faraday is no longer in general use and has been replaced by the SI unit coulomb; one faraday is approximately equivalent to 96485.3415 coulombs.

Like the farad, the faraday was named after Michael Faraday.
