Why does the USA use 110V and UK use 230-240V?

Since electricity is metered in kilowatt hours, it's much easier to see the running costs of a device with a power given in that unit.

When picking an AC unit, running cost is not the primary concern: sizing is the primary concern. If you pick too large or small of a unit you will have issues. Too small won't be able to cool, too large generally won't be able to bring humidity down (outside of the newer inverter units that can run slower for longer).

Tons (or, BTUs of cooling) makes more sense, because the efficiency for a given cooling amount is variable.

For efficiency, we have efficiency ratings in the SEER/SEER2 ratings.

Kilowatts are ambiguous between amount of cooling and amount of electricity used.
