FAQ
What is the conversion factor from H to nH?
1 H equals 1e+9 nH. To convert, multiply the value in henries by 1e+9.
How do I convert 1 H to nH?
1 H = 1e+9 nH. For any value, multiply by 1e+9.
How do I convert nH back to H?
Divide by the same factor — or equivalently, multiply by 1e-9. So 1 nH = 1e-9 H.
When would I need to convert henry to nanohenry?
Inductance conversions between H and nH are used in transformer and reactor design, EMI filter sizing, switched-mode power supply development and sensor coil specification. Henries cover power-inductor and choke ratings; millihenries through nanohenries cover signal-path filters and high-frequency electronics.
Is the conversion exact?
Yes. Both H and nH are defined by exact SI relationships, so the displayed factor is exact (any rounding shown is only for display).
