How to convert electron charge to coulombs
To convert electron charges (e) to coulombs (C), multiply by 1.602176634 × 10⁻¹⁹.
C = e × 1.602176634 × 10⁻¹⁹
The elementary charge (e) is exactly 1.602176634 × 10⁻¹⁹ coulombs by definition since the 2019 SI redefinition.
Example: Convert 6.241509074 × 10¹⁸ electron charges to C:
6.241509074 × 10¹⁸ × 1.602176634 × 10⁻¹⁹ = 1 C

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