Henries to millihenries
Type a value in H to get it in mH instantly.
10,000mH
That's about the same as a transformer winding. With a 100 nF capacitor that resonates near 0.1592 kHz.
Convert the other way: mH to H
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 H to mH
To convert henries to millihenries, multiply by 1,000.
Example: 10 H × 1,000 = 10,000 mH.
In the other direction, 1 mH = 0.001 H.
