Nu=[itex]\frac{hD}{k}[/itex]

his the heat transfer coefficient, andDis the diameter of the pipe in which heat transfer takes place...

..but what are the dimensions ofkin terms of mass (M), length (L), time (T) and temperature ([itex]\theta[/itex])?

So far, I've worked out that the units for h are J/(m^{2}hr C), but I'm having difficulty expressing k in terms of what is given.

Am I wrong is thinking that J/(m^{2}hr C) can be expressed as W/(m^{2}K)? I'm thinking that this is relevant to the end units of k, but I am unsure if the dimensions are correct.
