1,000,000,000 (one billion, short scale; one thousand million or one milliard, one yard, [1] long scale) is the natural number following 999,999,999 and preceding 1,000,000,001. With a number, "billion" can be abbreviated as b, bil [2] or bn. [3] [4] In standard form, it is written as 1 × 10 9. The metric prefix giga indicates 1,000,000,000 ...
For identical names, the long scale grows by multiples of one million (10 6), whereas the short scale grows by multiples of one thousand (10 3). For example, the short scale billion is one thousand million (10 9), whereas in the long scale, billion is one million million (10 12). The long scale system includes additional names for interleaved ...
[1] [2] [3] 1,000,000,000,000, i.e. one million million, or 10 12 (ten to the twelfth power), as defined on the long scale. This number is the historical sense of the word and remains the established sense of the word in other European languages.
Traditional British usage assigned new names for each power of one million (the long scale): 1,000,000 = 1 million; 1,000,000 2 = 1 billion; 1,000,000 3 = 1 trillion; and so on. It was adapted from French usage, and is similar to the system that was documented or invented by Chuquet .
