# Problem using UnitConvert

As we know in physics, power = torque * (angular velocity). But when I use UnitConvert to convert a quantity expressing power/(angular velocity) into newton-meters, UnitConvert fails.

How can they be incompatible units? How do I deal with it?

"Revolutions" is not immediately recognized as a special unit. So, preprocess first with UnitSimplify[]:
UnitConvert[UnitSimplify[Quantity[335, "Kilowatts"]/
