How to convert coulombs to electron charge
To convert coulombs (C) to electron charge (e), multiply by 6.241509074 × 10¹⁸.
e = C × 6.241509074 × 10¹⁸
One electron carries a charge of approximately 1.602176634 × 10⁻¹⁹ coulombs, so one coulomb equals about 6.242 × 10¹⁸ electron charges.
Example: Convert 1 C to electron charges:
1 × 6.241509074 × 10¹⁸ = 6.241509074 × 10¹⁸ e

How this calculator works
The form on this page is a Coulombs-to-Electron Charge converter. After you enter a number, JavaScript multiplies or rearranges it with the published conversion factor and writes the e result in the output box. The step-by-step panel repeats the arithmetic so you can copy it into homework or a spreadsheet.
