HtokH
Convert henries (H) to kilohenries (kH).
Factor1 H = 0.001 kH
Converter
H
Accepts numbers or expressions, e.g. 150 + 14.7
Result
kH
Rendered to 6 significant figures.
Formula
Formula
kH = H × 0.001
Multiply any value in henries by 0.001 to obtain the value in kilohenries.
Worked example
Convert 1000 H to kH.
- 01Start with 1000 H.
- 02Multiply by the conversion factor: 1000 × 0.001 = 1 kH.
Result1000 H = 1 kH

FAQ
What is the conversion factor from H to kH?
1 H equals 0.001 kH. To convert, multiply the value in henries by 0.001.
How do I convert 1 H to kH?
1 H = 0.001 kH. For any value, multiply by 0.001.
How do I convert kH back to H?
Divide by the same factor — or equivalently, multiply by 1000. So 1 kH = 1000 H.
When would I need to convert henry to kilohenry?
Inductance conversions between H and kH 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?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
