A **million** is 10^{6}, or 1,000,000. A **billion** is one thousand million, or 1,000,000,000 (10^{9}). This is the common usage in English-speaking countries and is called the *short scale*. Countries in continental Europe and Latin America use the *long scale* where a billion is a million millions (10^{12}).

The word *billion* originated from French word bi- (“two”) + -illion; i.e. a million million. It was first coined by Jehan Adam in 1475 as by-million and then rendered as byllion by Nicolas Chuquet in 1484.

*Million* originated from the Italian *milione*, from the Latin *mille* + the augmentative suffix -*one*.
