In general you can't assume a combination of SI units automatically makes another SI unit.

Newton is a force.
m2 is an area.
So a N/m2 is a unit of what?

Why not? Any combination of SI units is another SI unit. Whether it is the unit of something physical or has its own name is another question, but it is still in the realm of the system.

So what is the SI unit (singular) of torque? You can express torque in SI units (plural) but there isn't an SI unit of torque. That what I meant.
