How to Convert Coulombs to Elementary Charges
To convert from coulombs (C) to elementary charges (e), you divide the charge in coulombs by the elementary charge constant, which is approximately 1.602176634 × 10⁻¹⁹ coulombs per elementary charge. For more information about coulombs as a unit of measurement, visit our coulombs page.
Formula
Elementary Charges = Coulombs / (1.602176634 × 10⁻¹⁹)
or
e = C / 1.602176634e-19
Examples
- 1.602176634 × 10⁻¹⁹ C = 1.602176634 × 10⁻¹⁹ / (1.602176634 × 10⁻¹⁹) = 1 e
- 1 × 10⁻¹⁸ C = 1 × 10⁻¹⁸ / (1.602176634 × 10⁻¹⁹) = 6.241509 e
- 1 × 10⁻¹⁵ C = 1 × 10⁻¹⁵ / (1.602176634 × 10⁻¹⁹) = 6,241.509 e
- 1 × 10⁻¹² C = 1 × 10⁻¹² / (1.602176634 × 10⁻¹⁹) = 6,241,509 e

Frequently Asked Questions
What is a coulomb (C)?
The coulomb is the SI unit of electric charge, defined as the amount of charge transported by a constant current of one ampere in one second.
What is an elementary charge (e)?
The elementary charge is the electric charge carried by a single proton or, equivalently, the magnitude of the electric charge of a single electron. It is a fundamental physical constant, approximately 1.602176634 × 10⁻¹⁹ coulombs.
How do I convert elementary charges to coulombs?
To convert from elementary charges to coulombs, you multiply the number of elementary charges by 1.602176634 × 10⁻¹⁹. For example, 1 e is equal to 1 * 1.602176634 × 10⁻¹⁹ = 1.602176634 × 10⁻¹⁹ C.
