Alice.V em 21/06/20 20:55 comentada em 19/08/2020 16:43 In British English, a billion used to be equivalent to a million million (1,000,000,000,000), while in American English it has always meant a thousand million (1,000,000,000). Although British English adopted the American figure in 1974, there remains some old usage in certain documents that may lead to confusion. Currently a billion equals a thousand million in both varieties of English.
