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 1×106 or just 106. 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'.
