About Converting Revolutions per second to Millihertz
Revolutions per second and Millihertz 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 millihertz is 0.001 hertz units.
Formula
millihertz = revolutions per second × 1000
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 millihertz equals 0.001 base units, so dividing one by the other gives the direct revolutions per second-to-millihertz factor of 1000.
Simple example
1 rps × 1000 = 1,000 mHz
1 revolutions per second = 1,000 millihertz.
Real-world example
1,000 rps × 1000 = 1,000,000 mHz
1,000 revolutions per second = 1,000,000 millihertz.
Conversion table

| 60 rps | 60,000 mHz |
| 600 rps | 600,000 mHz |
| 1,000 rps | 1,000,000 mHz |
| 3,000 rps | 3,000,000 mHz |
| 6,000 rps | 6,000,000 mHz |
| 10,000 rps | 10,000,000 mHz |
Reverse conversion: Millihertz to Revolutions per second
1 mHz × 0.001 = 0.001 rps
1 millihertz = 0.001 revolutions per second.
revolutions per second = millihertz × 0.001

Frequently asked questions
How many millihertz are in 1 revolutions per second?
1 revolutions per second equals 1,000 millihertz, using the exact defined conversion factor rather than an estimate.
How do I convert revolutions per second to millihertz?
Multiply the revolutions per second value by 1000. The converter above does this instantly to whatever precision you set.
How do I convert millihertz back to revolutions per second?
Use the reverse factor: 1 millihertz equals 0.001 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 millihertz?
Millihertz (mHz) is a unit of frequency.
Is the revolutions per second to millihertz conversion exact?
Yes. Both revolutions per second and millihertz are defined by fixed standards rather than physical artifacts, so the factor of 1000 used above is exact to as many digits as you choose to display.
