In a nutshell, a Volt-Amp is a Watt, when dealing with a purely resistive load. But most loads are inductive or capacitive to some degree, so their wattage will actually be less than the volt-amps they pull through a transformer. Consumers look for watts because that's simpler. But the electricians need to know volt-amps to make sure equipment is sized properly.
