Thanks in advance, With the default Mathematica installation you can do: In[1]:= Sqrt[Meter^2/Second^2] Second/Meter^2 // PowerExpand Out[1]= 1/Meter But from my viewpoint a better solution is to install the package AutomaticUnits which can be found at: <http://library.wolfram.com/infocenter/MathSource/7655/> With that package installed, Mathematica does: In[1]:= << AutomaticUnits` In[2]:= Sqrt[Meter^2/Second^2] Second/Meter^2 Out[2]= m^-1
