In [[physical chemistry]], the '''Faraday constant''' (symbol {{math|''F''}}, sometimes stylized as ℱ) is a [[physical constant]] defined as the quotient of the total [[electric charge]] ({{math|''q''}}) by the [[amount of substance|amount]] ({{math|''n''}}) of [[elementary charge carrier]]s in any given sample of matter: {{nowrap|{{math|''F''}} {{=}} {{math|''q''/''n''}};}} it is expressed in [[unit of measurement|units]] of [[coulomb]]s per [[mole (unit)|mole]] (C/mol). 
As such, it represents the "[[molar quantity|molar]] [[elementary charge]]",<ref name="SI2019" /> that is, the electric charge of one mole of elementary carriers (e.g., protons).  It is named after the English [[scientist]] [[Michael Faraday]]. Since the [[2019 revision of the SI]],<ref name="SI2019">{{Cite book |last=Newell |first=David B. |url=https://www.nist.gov/si-redefinition/meet-constants |title=The International System of Units (SI) |last2=Tiesinga |first2=Eite |publisher=National Institute of Standards and Technology |year=2019 |series=NIST Special Publication 330 |location=Gaithersburg, Maryland |doi=10.6028/nist.sp.330-2019 |doi-access=free |s2cid=242934226}}</ref> the Faraday constant has an exactly defined value, the product of the elementary charge ({{math|''e''}}, in coulombs) and the [[Avogadro constant]] ({{math|''N''<sub>A</sub>}}, in reciprocal moles):
