Electric Charge Units & Calculator
Ampere-hours measure charge, not energy. Battery energy additionally depends on voltage.
Detailed explanation & worked examples
Conversion method
Base value = input × source factor + source offset. Output = (base value − target offset) ÷ target factor. Only units from this family can be converted together.
Worked example
For the first two units below: 1 Coulomb becomes 1000.00000000 Millicoulomb.
| Unit | Multiplier | Offset |
|---|---|---|
| Coulomb | 1 | 0 |
| Millicoulomb | 0.001 | 0 |
| Ampere-hour | 3600 | 0 |
| Milliampere-hour | 3.6 | 0 |
