How many electrons are in a coulomb?

Answer: The amount of power carried by a one-ampere current in a single second is measured in coulombs.

It is roughly equivalent to 6.24 × 10¹⁸ electrons.

The physical unit SI system is based on the Coulomb, the electrical charge unit of the meter-kilogram-second-ampere system.

Coulombs and electron charges are both used to measure electric charge.
