Because we're needlessly pedantic, that's why. The internet exists to allow us to have pointless arguments over things that don't matter, for no other reason than that we think another person is saying something which is not entirely true. There's not much point in discussing how much oil 190 million gallons is, either. Personally I'd say it's enough to fill the world's largest supertanker about 1.3 times over, but that doesn't sound very spectacular.
