Look up million in Wiktionary, the free dictionary.

One million (1,000,000) or one thousand thousand, is the natural number following 999,999 and preceding 1,000,001. The name is derived from Italian, where mille was 1,000, and 1,000,000 became milione, "a large thousand"^{[citation needed]}.

In scientific notation, it is written as 1×10⁶ or just 10⁶.^[1] 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 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 a hyperbole, as in "I've walked a million miles".

Il Milione is the title of Marco Polo's narration of his travel to China. The name is supposed to come from Polo's nickname after his tales of riches and multitudes^{[citation needed]}.

[edit] Visualizing one million

Although it is often stressed that counting to precisely a million would be an exceedingly tedius task due to the time and concentration required, there are many ways to bring the number "down to size" in approximate quantities, ignoring irregularities or packing effects.

• Information: Not counting spaces, the text on 136 pages of an Encyclopedia Britannica, or 600 pages of pulp paperback fiction contains approximately one million characters.
• Length: A typical car tire might rotate a million times in a 1,200 mile trip, while the engine would do several times that number of revolutions.
• Area: A square a thousand objects or units on a side contains a million such objects or square units, so a million holes might be found in less than three square yards of window screen, or similarly, in about one half square foot (400-500 cm²) of bed sheet cloth.
• Volume: The cube root of one million is only one hundred, so a million objects or cubic units is contained in a cube only a hundred objects or linear units on a side. A million grains of table salt or granulated sugar occupies only about 64 ml, slightly over a quarter of a cup, the volume of a cube one hundred grains on a side.
• Landscape: A pyramidal shaped hill 600 feet wide at the base and 100 feet high would weigh about a million tons.
