The unit of electric charge is the Coulomb.
It's the amount of charge on 6,242,197,000,000,000,000 (6.242 x 1018) electrons (or protons).
It's also the amount of charge that passes a point in one second in a conductor carrying 1 Ampere of current.

an electrical charge is measured in Coulombs, which is equal one ampere-second. That is, one ampere of current through a plane is equivalent to one coulomb of charge passing through the plane per second.Current
The SI derived unit of electric charge is the coulomb(C).In electrical engineering, it is also common to use the ampere-hour (Ah).In chemistry and particle physics, it is common to use the elementary particle charge (e) as a unit.Independent of units, the symbol Q often denotes charge.
Electric current is the rate of charge flow past a given point in an electric circuit, measured in Coulombs/second which is named Amperes. In most DC electric circuits, it can be assumed that the resistance to current flow is a constant so that the current in the circuit is related to voltage and resistance by Ohm's law. The standard abbreviations for the units are 1 A = 1C/s.
Current is the flow of electric charge or the rate of the flow of an electric charge through a conductor.
The SI unit of electric current is the ampere. While it is an SI base unit, it can also be considered to be a combined unit, coulombs per second.
