hectohenry to millihenry
Convert hectohenry (hH) to millihenry (mH). Use an editable inductance converter, conversion formula, and reference table.
1 hH = 100,000 mH
Conversion formula
One hectohenry equals 100,000 millihenry. Multiply your value in hectohenry by this factor to get millihenry. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 hectohenry:5 × 100,000 = 500,000 mH

About these measurements
Inductance describes the relationship between changing current and induced voltage.
The base reference used here is the henry. One hectohenry is 100 base units; one millihenry is 0.001 base units.
Important distinctions
A prefix changes only the scale of the inductance unit.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert hH to mH?
Multiply the quantity in hH by 100,000. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the millihenry to hectohenry converter.
