# Rotational Power Calculator

The rate at which a task or work is done is power. The power depends on the torque and the frequency of the rotation. Use our online rotational power calculator to find the power in rotational systems by entering torque and revolutions per minute(rpm). You can calculate rotational power in watt, autowatt, BTU/hour, erg/hour, gigawatt, kilowatt, megawatt, newton meter/hour, horsepower [electric], dyne meter/hour, electric horsepower and atmosphere cubic foot/hour.

### Example:

If the torque is 50 Nm and RPM is 70, find rotational power?

#### Solution:

Rotational Power = 50 * 2*3.14 * 70 / 60

= 366.51914250000004 W
