Template:Redirect Template:Pp-vandalism Template:EngvarB Template:Infobox number Template:Sister project 1,000,000 (one million), 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 (milione in modern Italian), from mille, "thousand", plus the augmentative suffix -one.<ref>Template:Cite web</ref>

It is commonly abbreviated:

In scientific notation, it is written as Template:Val or 106.<ref>Template:Cite book</ref> Physical quantities can also be expressed using the SI prefix mega (M), when dealing with SI units; for example, 1 megawatt (1 MW) 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".

1,000,000 is also the square of 1000 and the cube of 100.

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.

In Indian English and Pakistani English, it is also expressed as 10 lakh. Lakh is derived from Template:Transliteration for 100,000 in Sanskrit.
