Microcoulomb quick reference
| Microcoulomb | Coulomb | Milliampere-hour | Millicoulomb |
|---|---|---|---|
| 1 µC | = 0.000001 C | ≈ 2.777777778e-7 mAh | = 0.001 mC |
| 10 µC | = 0.00001 C | ≈ 0.000002777777778 mAh | = 0.01 mC |
| 100 µC | = 0.0001 C | ≈ 0.00002777777778 mAh | = 0.1 mC |
| 1000 µC | = 0.001 C | ≈ 0.0002777777778 mAh | = 1 mC |
Where the microcoulomb fits
The next smaller electric charge unit is the nanocoulomb (nC). 1 µC = 1000 nC, and 1 nC = 0.001 µC.
The next larger electric charge unit is the millicoulomb (mC). 1 µC = 0.001 mC, and 1 mC = 1000 µC.
