Enter the Kv rating and the voltage (volts) into the Calculator. The calculator will evaluate the RPM from Kv Rating.

## RPM from Kv Rating Formula

RPM = Kv * V

Variables:

- RPM is the RPM from Kv Rating (rotations per minute)
- Kv is the Kv rating
- V is the voltage (volts)

To calculate RPM from Kv Rating, multiply the Kv rating by the voltage.

## How to Calculate RPM from Kv Rating?

The following steps outline how to calculate the RPM from Kv Rating.

- First, determine the Kv rating.
- Next, determine the voltage (volts).
- Next, gather the formula from above = RPM = Kv * V.
- Finally, calculate the RPM from Kv Rating.
- 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.

Kv rating = 67

voltage (volts) = 80
