Answer 2

As said before it is British thermal units and the reason you want to match this up to the size of your room is, you have to custom tailor the size of the a/c unit to your room, if the unit doesn't put out enough btu, it will never be effective enough to cool the room completely, if too high on btu's it will cycle the compressor off too often and the same thing will happen, plus it wastes energy.
