Visualisation of powers of 10 from one to 1 billion. A power of 10 is any of the integer powers of the number ten; in other words, ten multiplied by itself a certain number of times (when the power is a positive integer). By definition, the number one is a power (the zeroth power) of ten. The first few non-negative powers of ten are:
Billion. 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. This is now the most common sense of the word in all varieties of English; it has long been established in American English and has since become common in ...
Scientific notation was created to handle the wide range of values that occur in scientific study. 1.0 × 10 9, for example, means one billion, or a 1 followed by nine zeros: 1 000 000 000. The reciprocal, 1.0 × 10 −9, means one billionth, or 0.000 000 001.
Usage of names of large numbers. Some names of large numbers, such as million, billion, and trillion, have real referents in human experience, and are encountered in many contexts. At times, the names of large numbers have been forced into common usage as a result of hyperinflation.
For identical names, the long scale proceeds by powers of one million, whereas the short scale proceeds by powers of one thousand. For example, the short scale "one billion" (in many languages other than English called "one milliard", even on the short scale) means one thousand million (1,000,000,000), whereas in the long scale, "one billion ...
Giga- ( / ˈɡɪɡə / or / ˈdʒɪɡə /) is a unit prefix in the metric system denoting a factor of a short-scale billion or long-scale milliard (10 9 or 1,000,000,000 ). It has the symbol G . Giga- is derived from the Greek word γίγας ( gígas ), meaning "giant". The Oxford English Dictionary reports the earliest written use of giga in ...
In the Western system, the next powers of ten are called one hundred thousand, one million, ten million, one hundred million, one billion ( short scale )/one thousand million ( long scale ), and so on; in the short scale, there are new words for every third power of ten (103n): million (106), billion (109), trillion (1012), etc.
Words with the suffix -illion (e.g., zillion, [28] gazillion, [29] bazillion, [30] jillion, [31] bajillion, [32] squillion, [33] and others) are often used as informal names for unspecified large numbers by analogy to names of large numbers such as million (10 6 ), billion (10 9) and trillion (10 12 ). In Estonian, the compound word mustmiljon ("black million") is used to mean an unfathomably ...
