How to use it
- Type the value in the revolutions per minute box.
- Read the result in revolutions per second as you type, and pick the precision you need.
- Swap the direction to convert back, or copy the result.
How it is calculated
rps = rpm × 0.01666666667
Multiply the value in revolutions per minute by 0.01666666667 to get revolutions per second.
Example
To convert 25 rpm to revolutions per second: 25 × 0.01666666667 = 0.416667 rps.

About the units
- Revolution per minute
- Full turns per minute, with each turn 2π radians, so 1 rpm is exactly 2π/60 rad/s (about 0.10472). It is the unit on engine tachometers, drills and washing machines.
- Revolution per second
- Full turns per second, so 1 rps is exactly 2π rad/s and 60 rpm.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many revolutions per second are in one revolution per minute?
1 rpm = 0.0166667 rps exactly.
How do I convert revolutions per minute to revolutions per second?
Use rps = rpm × 0.01666666667. For example, 25 rpm = 0.416667 rps.
How many revolutions per minute are in one revolution per second?
1 rps = 60 rpm.
How do I convert rpm to radians per second?
Multiply the rpm by 2π and divide by 60. For example 3000 rpm is 100π, about 314.16 rad/s.
Is angular speed the same as frequency in hertz?
No. Frequency counts turns per second, while angular speed in rad/s is the frequency times 2π. So a rotation at 1 Hz is 6.2832 rad/s.
