[3.5a] Dealing with units

Hello all.
I'm using Comsol 3.5a (PDE, Weak form) to deal with some mechanical problem, and beside some other issues with wich I'll deal later (such as moving mesh), I'm currently annoyed by the fact that I don't manage to get the units to work properly.
In spite of having all the constants set to a specific unit, all my scalar expressions have the same exasperating red brackets. It's not really a big issue and it does not stop the simulations.
I just hope the problem is not that I've missed some lines on the documentation, but I take it to be because I can't set the units of my problem variables (being u, v - displacement - and p - pressure). I really hope that's not a silly question, but do anyone know where to set those units (most likely m and Pa) ?
Thanks
