- 1 C = 6.24150907446e18 e
- 1 × 6.24150907446e18 = 6.24150907446e18 e
How to convert coulombs to elementary charges
1 C = 6.24150907446 × 10¹⁸ e, so multiply by 6.24150907446 to go from coulombs to elementary charges (one electron's charge). Going the other way, 1 e = 1.602176634 × 10⁻¹⁹ C.
e = C × 6.24150907446 C = e × 1.602176634
Worked example:
1 C = 6.24150907446e18 e 5 × 6.24150907446e18 = 3.12075453723e19 e
