# Million

**One million** (1,000,000), or one thousand thousand, is the natural number after 999,999 and before 1,000,001. The name is derived from Italian, where "*mille*" was 1,000, and 1,000,000 became a "*milione*", as 'a large thousand'.

In scientific notation, the number is written as 1×10^{6} or just 10^{6}. Physical quantities can also be expressed using the SI prefix "mega-" when dealing with SI units. For example, 1 megawatt equals 1,000,000 watts.

The word 'million' is common to both the short-scale and long-scale numbering systems, unlike the larger numbers, which have different names in the two systems.

The million is sometimes used in the English language as a metaphor for a very large number, as in 'Never in a million years' and 'You're one in a million', or as hyperbole, as in 'I've walked a million miles'.

*Il Milione* is the title of Marco Polo's narration of his travels in China. The name is supposed to come from Polo's nickname after his tales of riches and multitudes.
