Billion (disambiguation)

A billion, according to normal modern usage in both British and American English, is the number 1,000,000,000, i.e. one thousand million, or 10⁹ (ten to the ninth power).^[1] This is the short scale billion.

Formerly, in British usage, the long scale billion was used, denoting 1,000,000,000,000, i.e. one million million, or 10¹² (ten to the twelfth power). This is one thousand times larger than the short scale billion, and equivalent to the short scale trillion.

Another word for one thousand million is milliard, but this is used much less often in English than billion. Some languages, such as French, use milliard (or a related word) for the short scale billion, and billion (or a related word) for the long scale billion. Thus the French billion is a thousand times larger than the modern English billion.
