Millihenry quick reference
| Millihenry | Henry | Microhenry | Nanohenry |
|---|---|---|---|
| 1 mH | = 0.001 H | = 1000 µH | = 1000000 nH |
| 10 mH | = 0.01 H | = 10000 µH | = 10000000 nH |
| 100 mH | = 0.1 H | = 100000 µH | = 100000000 nH |
| 1000 mH | = 1 H | = 1000000 µH | = 1000000000 nH |
Where the millihenry fits
The next smaller inductance unit is the microhenry (µH). 1 mH = 1000 µH, and 1 µH = 0.001 mH.
The next larger inductance unit is the henry (H). 1 mH = 0.001 H, and 1 H = 1000 mH.
