"100 million" redirects here. For the song by Birdman, see 100 Million.

100,000,000 (one hundred million) is the natural number following 99,999,999 and preceding 100,000,001.

In scientific notation, it is written as 108.

East Asian languages treat 100,000,000 as a counting unit, significant as the square of a myriad, also a counting unit. In Chinese, Korean, and Japanese respectively it is yi (simplified Chinese: 亿; traditional Chinese: 億; pinyin: yì) (or Chinese: 萬萬; pinyin: wànwàn in ancient texts), eok (억/億) and oku (億). These languages do not have single words for a thousand to the second, third, fifth powers, etc.

100,000,000 is also the fourth power of 100 and also the square of 10000.
