Revolution per Second (rps)
Revolutions per second count full turns each second; one revolution per second is a rotational frequency of 1 Hz.
Symbol: rps
Quantity: frequency and rotational speed
SI relation: 1 rps = 1 Hz (exact)
Derivation: 1 rev/s = 1 Hz.
Exact: yes, by definition
Same quantity as hertz (Hz) : the factor between them is exactly 1.
Typical uses
- Turbines and centrifuges
- Rotational speed in SI-style calculations
