Torque Explained

In the simplest sense Torque = Force * Length 

Torque is derived and traceable to SI units of length,  mass,  and time.

The meter is the length of the path traveled by light in vacuum during a time interval of 1/299 792 458 of a second.
The kilogram is the unit of mass; it is equal to the mass of the international prototype of the kilogram.

The second is the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyper-fine levels of the ground state of the cesium 133 atom.

Torque, also called moment or moment of force is the tendency of a force to rotate an object about an axis, fulcrum, or pivot. Just as a force is a push or a pull, a torque can be thought of as a twist.

To convert from one unit of torque to another, requires knowing the appropriate conversions.
