Nanohenry quick reference
| Nanohenry | Microhenry | Millihenry | Henry |
|---|---|---|---|
| 1 nH | = 0.001 µH | = 0.000001 mH | = 1e-9 H |
| 10 nH | = 0.01 µH | = 0.00001 mH | = 1e-8 H |
| 100 nH | = 0.1 µH | = 0.0001 mH | = 1e-7 H |
| 1000 nH | = 1 µH | = 0.001 mH | = 0.000001 H |
Where the nanohenry fits
The next larger inductance unit is the microhenry (µH). 1 nH = 0.001 µH, and 1 µH = 1000 nH.
