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 ...
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:
In the short scale, a billion (in many countries called a "milliard") means a thousand millions (1,000,000,000, which is 10 9), a trillion means one thousand billions (10 12), and so on. Thus, a short scale n -illion equals 10 3 n +3 .
(1 000 000 000 000 000 000 000; 1000 7; short scale: one sextillion; long scale: one thousand trillion, or one trilliard) ISO: zetta- (Z) Geo – Grains of sand: All the world's beaches combined have been estimated to hold roughly 10 21 grains of sand .
In science and engineering, the parts-per notation is a set of pseudo-units to describe small values of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction. Since these fractions are quantity-per-quantity measures, they are pure numbers with no associated units of measurement. Commonly used are parts-per-million ( ppm ...

An order-of-magnitude estimate of a variable, whose precise value is unknown, is an estimate rounded to the nearest power of ten. For example, an order-of-magnitude estimate for a variable between about 3 billion and 30 billion (such as the human population of the Earth) is 10 billion. To round a number to its nearest order of magnitude, one ...
