About these units
Coulombs
The coulomb is the SI unit of electric charge, the charge carried by a current of one ampere in one second. It equals about 6.24 × 10¹⁸ electrons.
Milliampere-hours
The milliampere-hour measures battery capacity: how much charge a battery delivers over time. A phone battery is often 3,000–5,000 mAh.
Conversion formula
To convert Coulomb to Milliampere-hour, multiply the value by 0.2777777778.
