One billion

File:Billion.jpeg
A **billion** is equal to 109 = 1,0003 = 1,000,000,000. Like a million, a billion is often used as an exaggeration to mean an indefinitely large number.

In the long scale, 109 is called **milliard**, whereas "billion" refers to 1012 = 1,000,000,000,000. These definitions are no longer used in English-speaking countries, but there are equivalents in other languages such as French and German.

To prevent confusion with the similar sounding "million", or with 1012, even some languages, such as Template:W, which otherwise use short scale, use the term "milliard" (Turkish: "milyar") for 109.
