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

About Converting Revolutions per second to Hertz
Revolutions per second and Hertz 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. Specifically: Revolutions per second, and the hertz is one cycle per second.
Formula
hertz = revolutions per second × 1
This factor comes from each unit's defined relationship to the category's base unit: 1 revolutions per second equals 1 base unit, and 1 hertz equals 1 base unit, so dividing one by the other gives the direct revolutions per second-to-hertz factor of 1.
Simple example
1 rps × 1 = 1 Hz
1 revolutions per second = 1 hertz.
Real-world example
1,000 rps × 1 = 1,000 Hz
1,000 revolutions per second = 1,000 hertz.
Conversion table
| Revolutions per second (rps) | Hertz (Hz) |
|---|---|
| 60 rps | 60 Hz |
| 600 rps | 600 Hz |
| 1,000 rps | 1,000 Hz |
| 3,000 rps | 3,000 Hz |
| 6,000 rps | 6,000 Hz |
| 10,000 rps | 10,000 Hz |
Reverse conversion: Hertz to Revolutions per second
1 Hz × 1 = 1 rps
1 hertz = 1 revolutions per second.
revolutions per second = hertz × 1

Understanding the Revolutions per second (rps)
Revolutions per second.
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.

Frequently asked questions
How many hertz are in 1 revolutions per second?
1 revolutions per second equals 1 hertz, using the exact defined conversion factor rather than an estimate.
How do I convert revolutions per second to hertz?
Multiply the revolutions per second value by 1. The converter above does this instantly to whatever precision you set.
How do I convert hertz back to revolutions per second?
Use the reverse factor: 1 hertz equals 1 revolutions per second. You can also use the swap control in the converter above to flip the direction instantly.
What is a revolutions per second?
Revolutions per second (rps) is a unit of frequency.
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.
Is the revolutions per second to hertz conversion exact?
Yes. Both revolutions per second and hertz are defined by fixed standards rather than physical artifacts, so the factor of 1 used above is exact to as many digits as you choose to display.
