  1. 1 e = 4.45049065e-23 Ah
  2. 1 × 4.45049065e-23 = 4.45049065e-23 Ah

How to convert elementary charges to ampere-hours

1 e = 4.45049065 × 10⁻²³ Ah, so multiply by 4.45049065 to go from elementary charges (one electron's charge) to ampere-hours. Going the other way, 1 Ah = 2.24694326681 × 10²² e.

Ah = e × 4.45049065
e = Ah × 2.24694326681

Worked example:

1 e = 4.45049065e-23 Ah
5 × 4.45049065e-23 = 2.225245325e-22 Ah
