Farad quick reference
| Farad | Microfarad | Nanofarad | Millifarad |
|---|---|---|---|
| 1 F | = 1000000 µF | = 1000000000 nF | = 1000 mF |
| 10 F | = 10000000 µF | = 10000000000 nF | = 10000 mF |
| 100 F | = 100000000 µF | = 100000000000 nF | = 100000 mF |
| 1000 F | = 1000000000 µF | = 1000000000000 nF | = 1000000 mF |
Where the farad fits
The next smaller capacitance unit is the millifarad (mF). 1 F = 1000 mF, and 1 mF = 0.001 F.
The next larger capacitance unit is the abfarad (abF). 1 F = 1e-9 abF, and 1 abF = 1000000000 F.
