Dimensions of k in Nusselt Number

[QUOTE="Jasones, post: 4065432, member: 437939"] [h2]Homework Statement [/h2] A common dimensionless group used in heat transfer calculations is defined as: Nu=[itex]\frac{hD}{k}[/itex] where h is the heat transfer coefficient, and D is the diameter of the pipe in which heat transfer takes place. Please determine the dimensions of the quantity k in terms of mass (M), length (L), time (T) and temperature ([itex]\theta[/itex]) and in terms of SI units. [h2]Homework Equations[/h2] Nu=[itex]\frac{hD}{k}[/itex] [h2]The Attempt at a Solution[/h2] So far, I've worked out that the units for h are J/(m[SUP]2[/SUP] hr C), but I'm having difficulty expressing k in terms of what is given. Am I wrong is thinking that J/(m[SUP]2[/SUP] hr C) can be expressed as W/(m[SUP]2[/SUP] K)? I'm thinking that this is relevant to the end units of k, but I am unsure if the dimensions are correct.
