Millihenries to henries
Type a value in mH to get it in H instantly.
0.01H
That's about the same as a mains choke. With a 100 nF capacitor that resonates near 5.033 kHz.
Convert the other way: H to mH
What it means
What is that coil?
The resonant frequency shown assumes a 100 nF capacitor, from f = 1 / (2π√(LC)).
The math
How to convert mH to H
To convert millihenries to henries, multiply by 0.001.
Example: 10 mH × 0.001 = 0.01 H.
In the other direction, 1 H = 1,000 mH.
