Solving custom transport equation in fluent

Hello everyone!

I am trying to solve this transport equation attached. The velocity is constant so it comes out of the derivative. Anyway, I noticed that the units of the diffusivity in fluent are in kg/ms while the units in my source term is supposed to be m2/s. Furthermore, the rho has to go and instead of having mass flow rate as flux, I just want velocity. Is it possible to make these changes without a UDF?
