It seems a bit finicky on input, declining to combine two equations that it can answer separately (try getting the relativistic kinetic energy of 1000kg at 0.85c in megatons of tnt). An issue I've never had with google.
On the other hand, since it actually knows the equations, it's a bit less work to set up the question. It's just disconcerting that a trivial unit conversion leads to it being completely lost.
