Power into Torque and vise versa

Ok, according to this revolution request Socialist seamates! a very useful calculator is one that can turn Torque into Power and vice versa. I proudly present two calculators which can be used for power to the torque (Power to the Torque!) and torque to the power conversion.

Torque into Power

Torque, Nm

Angular speed, rpm

Calculation precision

Digits after the decimal point: 3

Calculate

Power, Watt

 

Power, kW

Here are several lame formulae to support calculations:

where P is power (Watt or kWatt), τ is torque (Nm), ω is the angular velocity (radians per second), and dot represents the scalar product.
Calculator accepts angular speed in RPM (rounds per minute) and the conversion to radians per second is simple

since one round is radians.
