Microhenry quick reference
| Microhenry | Millihenry | Nanohenry | Henry |
|---|---|---|---|
| 1 µH | = 0.001 mH | = 1000 nH | = 0.000001 H |
| 10 µH | = 0.01 mH | = 10000 nH | = 0.00001 H |
| 100 µH | = 0.1 mH | = 100000 nH | = 0.0001 H |
| 1000 µH | = 1 mH | = 1000000 nH | = 0.001 H |
Where the microhenry fits
The next smaller inductance unit is the nanohenry (nH). 1 µH = 1000 nH, and 1 nH = 0.001 µH.
The next larger inductance unit is the millihenry (mH). 1 µH = 0.001 mH, and 1 mH = 1000 µH.
