Orders of magnitude

In English, the words "million" and "billion" differ by only one letter, yet that letter means that one of the words signifies something that is a thousand times larger than the other. A million is equal to one thousand thousands or 1,000,000, while a billion is equal to one thousand millions or 1,000,000,000. This means that a billion is a thousand times larger than a million.
