# Why can't the units of work and torque be interchanged? [duplicate]

When I'm studying about work and torque, I found that their unit are the same. But, why don't we use Joule (unit of work) instead of Newton-meter (unit of torque)? Since $\mathrm{1\ Joule = 1\ Nm}$, why can't they be interchanged?

• The question is a duplicate of the question Qmechanic linked, but all the same I'm surprised to see it aggressively downvoted. It seems to me to be a fair question, and duplicates are not always easy to find through the site search. – John Rennie Nov 17 '13 at 11:51
