You can use Power Expand to do this.
In[21]:=
?PowerExpand
PowerExpand[expr] expands nested powers, powers of products,
logarithms of powers, and logarithms of products.
PowerExpand[expr, {x1, x2, ...}] expands expr with
respect to the x1. Use PowerExpand with caution because
PowerExpand does not pay attention to branch cuts.
In[22]:=
PowerExpand[ Sqrt[Meter^2/Second^2] ]
Out[22]=
Meter
------
Second
I hope this helps.
