1,000,000
1,000,000, or one thousand thousand, is the natural number following 999,999 and preceding 1,000,001. The word is derived from the early Italian millione, from mille, "thousand", plus the augmentative suffix -one. It is commonly abbreviated as m or M and MM, mm, or mn in financial contexts.
In scientific notation, it is written as or 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 meaning of 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 "Not in a million years" and "You're one in a million", or a hyperbole, as in "I've walked a million miles" and "You've asked a million-dollar question".
Visualizing one million
Even though it is often stressed that counting to precisely a million would be an exceedingly tedious 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 printed on 136 pages of an Encyclopædia Britannica, or 600 pages of pulp paperback fiction contains approximately one million characters.
- Length: There are one million millimetres in a kilometre, and roughly a million sixteenths of an inch in a mile. A typical car tire might rotate a million times in a trip, while the engine would do several times that number of revolutions.
- Fingers: If the width of a human finger is, then a million fingers lined up would cover a distance of. If a person walks at a speed of, it would take them approximately five and a half hours to reach the end of the fingers.
- 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 of bed sheet cloth. A city lot 70 by 100 feet is about a million square inches.
- Volume: The cube root of one million is one hundred, so a million objects or cubic units is contained in a cube a hundred objects or linear units on a side. A million grains of table salt or granulated sugar occupies about, the volume of a cube one hundred grains on a side. One million cubic inches would be the volume of a small room feet long by feet wide by feet high.
- Mass: A million cubic millimetres of water would have a volume of one litre and a mass of one kilogram. A million millilitres or cubic centimetres of water has a mass of a million grams or one tonne.
- Weight: A million honey bees would weigh the same as an person.
- Landscape: A pyramidal hill wide at the base and high would weigh about a million short tons.
- Computer: A display resolution of 1,280 by 800 pixels contains 1,024,000 pixels.
- Money: A USD bill of any denomination weighs. There are 454 grams in a pound. One million USD bills would weigh or 1 tonne.
- Time: A million seconds, 1 megasecond, is 11.57 days.
