decihertz to hertz
Convert decihertz (dHz) to hertz (Hz). Use an editable frequency converter, conversion formula, and reference table.
1 dHz = 0.1 Hz
Conversion formula
One decihertz equals 0.1 hertz. Multiply your value in decihertz by this factor to get hertz. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 decihertz:5 × 0.1 = 0.5 Hz

About these measurements
Frequency measures cycles per second.
The base reference used here is the hertz. One decihertz is 0.1 base units; one hertz is 1 base units.
Important distinctions
Frequency is the reciprocal of period, not angular velocity.
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 dHz to Hz?
Multiply the quantity in dHz by 0.1. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the hertz to decihertz converter.
