How to Convert Electron Charge to Coulombs

To convert an electron charge measurement to a coulomb measurement, divide 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:

coulombs = electron charge ÷ 6.2415E+18

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

For example, here's how to convert 5.0E+18 electron charge to coulombs using the formula above.
5.0E+18 e = (5.0E+18 ÷ 6.2415E+18) = 0.801088 C

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

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.


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.
