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 ...
For whole numbers smaller than 1,000,000,000 (10 9 ), such as one thousand or one million, the two scales are identical. For larger numbers, starting with 10 9, the two systems differ. For identical names, the long scale proceeds by powers of one million, whereas the short scale proceeds by powers of one thousand.
This section illustrates several systems for naming large numbers, and shows how they can be extended past vigintillion . Traditional British usage assigned new names for each power of one million (the long scale ): 1,000,000 = 1 million; 1,000,0002 = 1 billion; 1,000,0003 = 1 trillion; and so on. It was adapted from French usage, and is ...
Trillion. Visualization of 1 trillion (short scale) A Rubik's cube, which has about 43 trillion (long scale) possible positions. Trillion is a number with two distinct definitions: 1,000,000,000,000, i.e. one million million, or 10 12 (ten to the twelfth power ), as defined on the short scale. This is now the meaning in both American and ...
In number theory, Skewes's number is any of several large numbers used by the South African mathematician Stanley Skewes as upper bounds for the smallest natural number for which. π x li x. where π is the prime-counting function and li is the logarithmic integral function. Skewes's number is much larger, but it is now known that there is a ...

Power of 10. Visualisation of powers of 10 from one to 1 trillion. 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:
