How to Convert Coulombs to Electron Charge

To convert a coulomb measurement to an electron charge measurement, multiply the electric charge by the conversion ratio.

Since one coulomb is equal to 6.2415E+18 electron charge, you can use this simple formula to convert:

electron charge = coulombs × 6.2415E+18

The electric charge in electron charge is equal to the coulombs multiplied by 6.2415E+18.

For example, here's how to convert 5 coulombs to electron charge using the formula above.
5 C = (5 × 6.2415E+18) = 3.1208E+19 e

How Many Electron Charge Are in a Coulomb?

There are 6.2415E+18 electron charge in a coulomb, which is why we use this value in the formula above.

1 C = 6.2415E+18 e

Coulombs and electron charge are both units used to measure electric charge. Keep reading to learn more about each unit of measure.


One coulomb is the electric charge equal to one ampere of current over one second.[1]

The coulomb can be expressed as QC = IA × ts

The charge in coulombs is equal to the current in amperes times the time in seconds.

The coulomb is the SI derived unit for electric charge in the metric system. Coulombs can be abbreviated as C; for example, 1 coulomb can be written as 1 C.

Electron Charge

Electron charge is equal to the charge of an electron, and is the inverse of elementary charge, which is the magnitude of the charge of a proton. It is equal to 1.602176634×10−19 coulombs, per the 2019 SI redefinition of the coulomb.

Electron charge can be abbreviated as e; for example, 1 electron charge can be written as 1 e.
