Electric Charge Converter
Coulombs, battery capacity (mAh, Ah), the faraday and CGS units. Turning mAh into watt-hours also needs the battery voltage.
That is below absolute zero (−273.15 °C), which isn’t physically possible.
1 Milliampere-hour = 3.6 Coulombs
Formula: multiply the electric charge value by 3.6
1 mAh in every electric charge unit

How to convert electric charge units
Coulombs, battery capacity (mAh, Ah), the faraday and CGS units. Turning mAh into watt-hours also needs the battery voltage. Every conversion goes through one base unit, the coulomb, using exact factors, so results don’t drift.
Milliampere-hours to ampere-hours (mAh to Ah)
To convert milliampere-hours to ampere-hours, divide by 1,000. 1 milliampere-hour = 0.001 ampere-hours.
| mAh | Ah |
|---|---|
| 1 mAh | 0.001 Ah |
| 2 mAh | 0.002 Ah |
| 5 mAh | 0.005 Ah |
| 10 mAh | 0.01 Ah |
| 20 mAh | 0.02 Ah |
| 50 mAh | 0.05 Ah |
| 100 mAh | 0.1 Ah |
Ampere-hours to milliampere-hours (Ah to mAh)
To convert ampere-hours to milliampere-hours, multiply by 1,000. 1 ampere-hour = 1,000 milliampere-hours.
| Ah | mAh |
|---|---|
| 1 Ah | 1,000 mAh |
| 2 Ah | 2,000 mAh |
| 5 Ah | 5,000 mAh |
| 10 Ah | 10,000 mAh |
| 20 Ah | 20,000 mAh |
| 50 Ah | 50,000 mAh |
| 100 Ah | 100,000 mAh |
Milliampere-hours to coulombs (mAh to C)
To convert milliampere-hours to coulombs, multiply by 3.6. 1 milliampere-hour = 3.6 coulombs.
Ampere-hours to coulombs (Ah to C)
To convert ampere-hours to coulombs, multiply by 3,600. 1 ampere-hour = 3,600 coulombs.
