Rough walls in CFX 4.X

We are having trouble relating the values of RFACT and RHT (Roughness height) in the USRWTM fortran subroutine to the equivalent roughness of the surfaces in our experiments.

Say the we in our experiments have found a surface roughness of 5 mm. How are we going to implement this in a model ?
