For example, the unit of angular velocity can be both 1/s and rad/s. So the unit you suggest for torque, Nm/rad is equivalent to Nm, which is also the unit of energy. | |

They are there to reduce the friction produced by each and every person using their personal unit system. We've lost mars probes due to people confusing their units. And the SI system is clear that the unit symbol for the Newton is $N$ and nothing else. | |

| Aug 26, 2020 at 4:19 | comment | added | BobT | I've upvoted you answer because it points at the basic problem, laziness using Nm to measure torque, and ignoring the angles. The units of Newton.metre are also used by engineers to describe bending moments in beams. It is always important to consider the angle between the force and the distance (or velocity or acceleration) . Technically one should be using complex numbers so work = Re{Force * Distance} and torque = Im{Force * Distance} | |
