Problems with integral of functions with unit

[pagheca]

I found the following problems with MathCAD 11.

I have to numerically integrate a function in the form F(f,k,T)=F(exp(-hf/kT)), where h, f, k and T have their own units. Most of you will have already understood I'm dealing with Planck radiation law, however...

I would prefer to keep working with units and here comes the problem: when I put F(f,k,T) under the integral sign the f becames red because "Can't have anything with units or dimensions here").

Does someone knows a workaround to solve the problem?

Thanks in advance
