The table of imperial avoirdupois mass is the same as the United States table up to one pound, but above that point, the tables differ. The imperial system has a hundredweight, defined as eight stone of 14 lb each, or 112 lb ( 50.802 345 44 kg ), whereas a US hundredweight is 100 lb ( 45.359 237 kg ).
Thus, a billion is 1000 × 1000 2 = 10 9; a trillion is 1000 × 1000 3 = 10 12; and so forth. Due to its dominance in the financial world (and by the US dollar), this was adopted for official United Nations documents. Traditional French usage has varied; in 1948, France, which had originally popularized the short scale worldwide, reverted to ...
Billion is a word for a large number, and it has two distinct definitions: 1,000,000,000 , i.e. one thousand million , or 10 9 (ten to the ninth power ), as defined on the short scale .

Each of these words translates to the American English or post-1974 British English word billion (10 9 in the short scale). The term billion originally meant 10 12 when introduced. [7] In long scale countries, milliard was defined to its current value of 10 9, leaving billion at its original 10 12 value and so on for the larger numbers. [7]
The brochure leaves some scope for local variations, particularly regarding unit names and terms in different languages. For example, the United States' National Institute of Standards and Technology (NIST) has produced a version of the CGPM document (NIST SP 330) which clarifies usage for English-language publications that use American English ...
The US survey acre is about 4,046.872 square metres; its exact value (4046 + 13,525,426 / 15,499,969 m 2) is based on an inch defined by 1 metre = 39.37 inches exactly, as established by the Mendenhall Order of 1893. [6] Surveyors in the United States use both international and survey feet, and consequently, both varieties of acre. [7]
