- 1 e = 4.45049065e-20 mAh
- 1 × 4.45049065e-20 = 4.45049065e-20 mAh
How to convert elementary charges to milliampere-hours
1 e = 4.45049065 × 10⁻²⁰ mAh, so multiply by 4.45049065 to go from elementary charges (one electron's charge) to milliampere-hours. Going the other way, 1 mAh = 2.24694326681 × 10¹⁹ e.
mAh = e × 4.45049065 e = mAh × 2.24694326681
Worked example:
1 e = 4.45049065e-20 mAh 5 × 4.45049065e-20 = 2.225245325e-19 mAh
