The coulomb, abbreviated C, is the SI unit of electric charge. It is defined as the amount of charge passing a point in one second in a circuit with one ampere of current.
The ampere is named for Charles-Augustin de Coulomb (1736 - 1806), a French physicist who developed the law of electrostatic attraction and repulsion, named Coulomb's Law in his honor.
The coulomb is a derived unit in the SI, equal to 1 A·s. One coulomb is about -6.2415·1018 times the charge on an electron.
