- 1 × 0.277777777778 = 0.277777777778 mAh
How to convert coulombs to milliampere-hours
1 C = 0.277777777778 mAh, so multiply by 0.277777777778 to go from coulombs to milliampere-hours. Going the other way, 1 mAh = 3.6 C.
mAh = C × 0.277777777778 C = mAh × 3.6
Worked example:
1 C = 0.277777777778 mAh 5 × 0.277777777778 = 1.38888888889 mAh
