How much is 6 billion?

Answer 1

In countries using the convention formerly known as the "short scale", 6 billion is 6 thousand million, or 6 thousand thousand thousand, or 6 x 10^9, 6 followed by nine zeroes. The adoption of the short scale by the United States led to its acceptance for general financial and trade usage. The short scale increases "-ion" named numbers (millions, billions) in factors of 1,000. The "long scale" used "-ion" numbers separated by a factor of a million (1,000,000) with intermediate "-iard" numbers representing thousands of those units. On the long scale, 6 billion would be 6 million million, 6 x 10^12, the same as the short scale " 6 trillion".
