- 1). Study the definition of a hertz. A hertz is one oscillation or revolution per second. Revolution is dimensionless and is abbreviated as rev, while second is abbreviated as s, so that 1 Hz = 1 rev/s.
- 2). Examine the equation to convert from RPM to Hz, which entails converting minutes to seconds. There are 60 seconds in a minute. Therefore, 1 RPM is 1 rev/min = (1 rev/min)(1 min/ 60 s) = 1 rev /60 s. This equation means that to in order to convert RPM to Hz, simply divide by 60.
- 3). Convert 3600 RPM to Hz. The answer is 60 Hz. This is because 3600 rpm = (3600 rev/min) (1 min/60 s) = 3600 rev/60 s = 60 rev/s = 60 hertz. Most often, rev is not explicitly written since it is not a unit.
