Convert RPM to Revolutions per Second (rpm to rps)
1 revolution per minute (rpm) = 0.01666666667 revolutions per second (rps). 1 rps = 60 rpm. Example: 15 rpm = 15 × 0.01666666667 = 0.25 rps.

How to Convert RPM to Revolution per Second
- 1 rpm = 0.01666666667 rps
- 1 rps = 60 rpm
- Example: convert 15 rpm to rps: 15 rpm = 15 × 0.01666666667 rps = 0.25 rps
Formula
rps = rpm × 0.01666666666667
or rps = rpm ÷ 60
Derivation from SI units:
- 1 rpm = 1/60 revolution per second = 1/60 Hz.
- 1 rev/s = 1 Hz.
- 1 rpm = 0.01666666666667 Hz ÷ 1 Hz per rps = 0.01666666666667 rps
Both units are defined exactly, so the factor is exact. RPM definition: revolution per minute; Revolution per Second definition: revolution per second.
Worked examples
- A reading of 750 rpm converts to 12.5 rps.
750 rpm × 0.01666666667 = 12.5 rps - A value of 1500 rpm is 25 rps.
1500 rpm × 0.01666666667 = 25 rps

Where it's used
RPM are used for engine and motor speeds, while revolutions per second appear in turbines and centrifuges. Both measure frequency and rotational speed, so the conversion is a fixed factor.

Frequently asked questions
How many revolutions per second are in 1 revolution per minute?
1 rpm = 0.01666666667 rps.
How do I convert revolutions per minute to revolutions per second?
Multiply the value in rpm by 0.01666666667, or divide it by 60. For example, 15 rpm × 0.01666666667 = 0.25 rps.
Is the rpm to rps conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
