Henry quick reference
| Henry | Millihenry | Microhenry | Nanohenry |
|---|---|---|---|
| 1 H | = 1000 mH | = 1000000 µH | = 1000000000 nH |
| 10 H | = 10000 mH | = 10000000 µH | = 10000000000 nH |
| 100 H | = 100000 mH | = 100000000 µH | = 100000000000 nH |
| 1000 H | = 1000000 mH | = 1000000000 µH | = 1000000000000 nH |
Where the henry fits
The next smaller inductance unit is the millihenry (mH). 1 H = 1000 mH, and 1 mH = 0.001 H.
The next larger inductance unit is the stathenry (statH). 1 H ≈ 1.112650056e-12 statH, and 1 statH = 898755178736.81764 H.
