Yes, you can't read too much into the meaning of a unit's dimensions.  
Force and torque have the same units (kg m^2/s^2) but are definitely not
the same thing.

I believe, but am not sure, that the electric and magnetic fields of a
photon are in a constant ratio, and if you divide its electric field
strength by its magnetic field strength, you get the velocity of the
photon, or c.  I'll have to look that up.
