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.
Here are a couple of lame formulae to support the calculations:
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
since one round is radians.
