Enter the hertz (hz) and the number of poles into the Calculator. The calculator will evaluate the RPM from Hz.

## RPM from Hz Formula

RPM = HZ * 60 * 2 / P

Variables:

- RPM is the RPM from Hz (rotations per minute)
- HZ is the hertz (hz)
- #P is the number of poles

To calculate RPM from Hz, multiply the hertz by 120, then divide by the number of poles.

## How to Calculate RPM from Hz?

The following steps outline how to calculate the RPM from Hz.

- First, determine the hertz (hz).
- Next, determine the number of poles.
- Next, gather the formula from above = RPM = HZ * 60 * 2 / #P.
- Finally, calculate the RPM from Hz.
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

hertz (hz) = 150

number of poles = 4
