Sounds like you only looked at part of the naming system. If you’re thinking of the prefix as showing how many groups of three zeros, then million is two (in the U.S.), not one, and billion is three.
The Brits, on the other hand, are counting blocks of six zeros. Million is one, billion is two, trillion is three…
Sure, here you go…
