You Brits and your logical, rational metric system. Pshaw! Personally, I measure everything in furlongs and stone.

1 firkin = 0.0001693544997216257 cubic furlong. See how simple that is?

What happens when you mix a man with too much time on his hands, a conversion table and a calculator?
You get a guy who could potentially hit the broad side of Mars with a probe, even if the original figures were metric. Just sayin'.

Ok, the question should have read: A man with a giant brain and too much time on his hands.

Yes, all those zeros are tricky little beggars.
