Tangential, but I've always wondered why in English 10^9 is one billion. 10^6 is one million. Twice as many zeroes should be one billion. Three times as many, one trillion, etc.
In Spanish they say "Octavos de Final", which literally means "Eighths of Final". I would probably say Eighths Final. And following that logic you would get Sixteenths Final, Thirty-seconds Final, etc.
