Quick answer

  • 1 coulomb = 6.2415091 × 1018 elementary charges
  • 1 elementary charge = 1.6021766 × 10-19 coulombs
  • Formula: e = C × 6.2415091 × 1018

1 coulomb = 6.2415091 × 1018 elementary charges

How to convert coulombs to elementary charges

e = C × 6.2415091 × 1018

To convert coulombs to elementary charges, multiply the number of coulombs by 6.2415091 × 1018.

Example: 10 C to e

  1. Start with the value in coulombs: 10 C.
  2. Multiply by 6.2415091 × 1018: 10 × 6.2415091 × 1018 = 6.2415091 × 1019.
  3. Result: 10 coulombs = 6.2415091 × 1019 elementary charges.

Going the other way, 1 elementary charge = 1.6021766 × 10-19 coulombs, so to convert elementary charges back to coulombs you divide by the same number. See elementary charges to coulombs.
