Context values
Some unit families need one extra value for a physically accurate result.
Kilohertz is 1000 hertz units.
Result = input x 1 / 1000.
Frequency uses hertz as the base unit.

About Converting Revolutions per second to Kilohertz
Revolutions per second and Kilohertz 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 kilohertz is 1000 hertz units.
Formula
kilohertz = revolutions per second × 0.001
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 kilohertz equals 1000 base units, so dividing one by the other gives the direct revolutions per second-to-kilohertz factor of 0.001.
Simple example
1 rps × 0.001 = 0.001 kHz
1 revolutions per second = 0.001 kilohertz.
Real-world example
1,000 rps × 0.001 = 1 kHz
1,000 revolutions per second = 1 kilohertz.
Conversion table
| Revolutions per second (rps) | Kilohertz (kHz) |
|---|---|
| 60 rps | 0.06 kHz |
| 600 rps | 0.6 kHz |
| 1,000 rps | 1 kHz |
| 3,000 rps | 3 kHz |
| 6,000 rps | 6 kHz |
| 10,000 rps | 10 kHz |
Reverse conversion: Kilohertz to Revolutions per second
0.001 kHz × 1000 = 1 rps
0.001 kilohertz = 1 revolutions per second.
revolutions per second = kilohertz × 1000

Frequently asked questions
How many kilohertz are in 1 revolutions per second?
1 revolutions per second equals 0.001 kilohertz, using the exact defined conversion factor rather than an estimate.
How do I convert revolutions per second to kilohertz?
Multiply the revolutions per second value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert kilohertz back to revolutions per second?
Use the reverse factor: 1 kilohertz equals 1,000 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 kilohertz?
Kilohertz (kHz) is a unit of frequency.
Is the revolutions per second to kilohertz conversion exact?
Yes. Both revolutions per second and kilohertz are defined by fixed standards rather than physical artifacts, so the factor of 0.001 used above is exact to as many digits as you choose to display.
