Context values
Some unit families need one extra value for a physically accurate result.
Centihertz is 0.01 hertz units.
Result = input x 1 / 0.01.
Frequency uses hertz as the base unit.

About Converting Hertz to Centihertz
Hertz and Centihertz both describe how fast something cycles or rotates, and the conversion is a routine part of reading a car tachometer or motor spec sheet against a scientific frequency figure. Hertz is most often used for electrical power frequency (50/60 hz worldwide).
Formula
centihertz = hertz × 100
This factor comes from each unit's defined relationship to the category's base unit: 1 hertz equals 1 base unit, and 1 centihertz equals 0.01 base units, so dividing one by the other gives the direct hertz-to-centihertz factor of 100.
Simple example
1 Hz × 100 = 100 cHz
1 hertz = 100 centihertz.
Real-world example
1,000 Hz × 100 = 100,000 cHz
1,000 hertz = 100,000 centihertz.
Conversion table
| Hertz (Hz) | Centihertz (cHz) |
|---|---|
| 60 Hz | 6,000 cHz |
| 600 Hz | 60,000 cHz |
| 1,000 Hz | 100,000 cHz |
| 3,000 Hz | 300,000 cHz |
| 6,000 Hz | 600,000 cHz |
| 10,000 Hz | 1,000,000 cHz |
Reverse conversion: Centihertz to Hertz
100 cHz × 0.01 = 1 Hz
100 centihertz = 1 hertz.
hertz = centihertz × 0.01

Understanding the Hertz
Hertz (Hz) measures frequency. The hertz is the SI derived unit of frequency: one cycle per second. It is classified as a SI derived unit.
Where it's used: Standard scientific unit worldwide; also everyday (AC power frequency, radio, audio)
Uses of the Hertz today
- Electrical power frequency (50/60 Hz worldwide)
- Radio, audio, and signal processing
- Computer processor clock speeds (GHz)
History of the Hertz
The hertz is named after Heinrich Hertz, who in 1886-1889 was the first to conclusively demonstrate the existence of electromagnetic waves predicted by Maxwell's equations. The unit ('cycles per second') was renamed in his honor and adopted internationally in 1930, becoming the SI derived unit of frequency in 1960.
Historical origin. Hertz was not the invention of a single named person; it developed through the process described above.
Understanding the Centihertz (cHz)
Centihertz is 0.01 hertz units.

Frequently asked questions
How many centihertz are in 1 hertz?
1 hertz equals 100 centihertz, using the exact defined conversion factor rather than an estimate.
How do I convert hertz to centihertz?
Multiply the hertz value by 100. The converter above does this instantly to whatever precision you set.
How do I convert centihertz back to hertz?
Use the reverse factor: 1 centihertz equals 0.01 hertz. You can also use the swap control in the converter above to flip the direction instantly.
What is a hertz?
Hertz (Hz) measures frequency. The hertz is the SI derived unit of frequency: one cycle per second. It is classified as a SI derived unit.
What is a centihertz?
Centihertz (cHz) is a unit of frequency.
Is the hertz to centihertz conversion exact?
Yes. Both hertz and centihertz are defined by fixed standards rather than physical artifacts, so the factor of 100 used above is exact to as many digits as you choose to display.
Where is the hertz still used today?
Standard scientific unit worldwide; also everyday (AC power frequency, radio, audio)
