Uh, no.
SI unit of Force: newton
Torque: newton meter
The dimensions of torque are also the dimensions of work (force x distance)
The difference in physics is the orientation: work is the product
of the component of the vector force parallel to the displacement
torque involves the force perpendicular to the displacement vector
(relative to some origin)
