About Converting Millihertz to Revolutions per second
Millihertz and Revolutions per second 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: Millihertz is 0.001 hertz units, and revolutions per second.
Formula
revolutions per second = millihertz × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 millihertz equals 0.001 base units, and 1 revolutions per second equals 1 base unit, so dividing one by the other gives the direct millihertz-to-revolutions per second factor of 0.001.
Simple example
1 mHz × 0.001 = 0.001 rps
1 millihertz = 0.001 revolutions per second.
Real-world example
1,000 mHz × 0.001 = 1 rps
1,000 millihertz = 1 revolutions per second.
Conversion table
| Millihertz (mHz) | Revolutions per second (rps) |
|---|---|
| 60 mHz | 0.06 rps |
| 600 mHz | 0.6 rps |
| 1,000 mHz | 1 rps |
| 3,000 mHz | 3 rps |
| 6,000 mHz | 6 rps |
| 10,000 mHz | 10 rps |
Reverse conversion: Revolutions per second to Millihertz
0.001 rps × 1000 = 1 mHz
0.001 revolutions per second = 1 millihertz.
millihertz = revolutions per second × 1000

Frequently asked questions
How many revolutions per second are in 1 millihertz?
1 millihertz equals 0.001 revolutions per second, using the exact defined conversion factor rather than an estimate.
How do I convert millihertz to revolutions per second?
Multiply the millihertz value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert revolutions per second back to millihertz?
Use the reverse factor: 1 revolutions per second equals 1,000 millihertz. You can also use the swap control in the converter above to flip the direction instantly.
What is a millihertz?
Millihertz (mHz) is a unit of frequency.
What is a revolutions per second?
Revolutions per second (rps) is a unit of frequency.
Is the millihertz to revolutions per second conversion exact?
Yes. Both millihertz and revolutions per second 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.
