Coulombs to Milliampere-hours Converter
1 coulomb (C) equals 0.277777777778 milliampere-hours (mAh).
Quick answer
- 1 coulomb = 0.2777777778 milliampere-hours
- 1 milliampere-hour = 3.6 coulombs
- Formula: mAh = C ÷ 3.6
1 coulomb = 0.2777777778 milliampere-hours
How to convert coulombs to milliampere-hours
mAh = C ÷ 3.6
To convert coulombs to milliampere-hours, divide the number of coulombs by 3.6.
Example: 42 C to mAh
- Start with the value in coulombs: 42 C.
- Divide by 3.6: 42 ÷ 3.6 = 11.66666667.
- Result: 42 coulombs = 11.66666667 milliampere-hours.
Going the other way, 1 milliampere-hour = 3.6 coulombs, so to convert milliampere-hours back to coulombs you multiply by the same number. See milliampere-hours to coulombs.
