The dimensional term in Planck's law (after getting rid of steradians) is

[itex]\frac{h c^2}{\lambda^5}[\itex]


Which seems to yield units of J*m/s. However, Wikipedia suggests that the units are J/(m3*s). If wikipedia is right, how do you get that answer?

How did you get J*m/s? There is a length to the 5th power in the denominator.

(the closing tag is [/itex])
