#### Electron Charge to Coulombs

Electron charge is equivalent to the magnitude of the elementary charge but bearing a negative sign. The symbol of electron charge is 'e'. The unit symbol of Coulomb is 'C'. This SI unit is named after Charles-Augustin de Coulomb. It is the International System of unit of electric charge. It is the charge transported by a constant current of one ampere in one second.

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

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.

#### Coulombs

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

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.
