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

#### Torque into Power

Digits after the decimal point: 3
Power, Watt

Power, kW

#### Power into Torque

Digits after the decimal point: 2
Torque, Nm

Here are a couple of lame formulae to support the calculations:

$P={\tau}{\omega} \\ \\ \tau=\frac{P}{\omega}$

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

$\omega=\frac{2{\pi}RPM}{60}$

since one round is $2{\pi}$ radians.
