Coulomb

The coulomb, symbol C, is the SI unit of electric charge, and is defined in terms of the ampere: 1 coulomb is the amount of electric charge carried by a current of 1 ampere flowing for 1 second. It is also about 6.24×1018 times the charge on an electron. It is named after Charles-Augustin de Coulomb (1736 - 1806).
