1 trillion consists of 1 followed by 12 zeros, that is, 1, 000, 000,000, 000 and can be written as 1012 (ten to the twelfth power). It takes about 32,000 years to finish 1 trillion seconds. [Note: The values which are greater than a trillion are called Quadrillion (1015)and Quintillion (1018).]
If you write a 1 followed by nine zeros, you get 1,000,000,000 = one billion! That's a lot of zeros! Astronomers often deal with even larger numbers such as a trillion (12 zeros) and a quadrillion (15 zeros).
Zillion is not actually a real number; it's simply a term used to refer to an undetermined but extremely large quantity.
Then comes quadrillion, quintrillion, sextillion, septillion, octillion, nonillion, and decillion.
a cardinal number represented in the U.S. by 1 followed by 303 zeros, and in Great Britain by 1 followed by 600 zeros.
A googol is 10 to the 100th power, which is 1 followed by 100 zeros. While this is an unimaginably large number, there's still an infinite quantity of larger numbers. One such number is googolplex, which is 10 to the power of a googol, or 1 followed by a googol of zeros.
noun. cen·til·lion sen-ˈtil-yən. often attributive. US : a number equal to 1 followed by 303 zeros see Table of Numbers. also, British : a number equal to 1 followed by 600 zeros see Table of Numbers.
It's infinity of course!” The only problem with infinity is that it isn't a number as such, as demonstrated by the conversation below between two bright sparks. Bright spark one: “Infinity is the biggest number in the world, that's easy!”
Google is the word that is more common to us now, and so it is sometimes mistakenly used as a noun to refer to the number 10100. That number is a googol, so named by Milton Sirotta, the nephew of the American mathematician Edward Kasner, who was working with large numbers like 10100.
A nonillion is a real number. The number nonillion is a very large number which is written as a 1 followed by 30 zeroes! It looks like this: 1,000,000,000,000,000,000,000,000,000,000.
With this definition, there is nothing (meaning: no real numbers) larger than infinity.
One trillion equals 1,000,000,000,000, i.e. one million million, and on the short scale, we write this as 1012 (ten to the twelfth power).
Nobody has ever defined how big a zillion is. A zillion can be used to describe a fictitious, indefinitely large number.
In the American system each of the denominations above 1,000 millions (the American billion) is 1,000 times the preceding one (one trillion = 1,000 billions; one quadrillion = 1,000 trillions).
Like zillion and jillion, gazillion is a made-up word meaning "a whole bunch" that's modeled after actual numbers such as million and billion.
But fair warning, Googolplex Written Out spans this many volumes: 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000. Each of those volumes holds a million zeros.
Then, you finally reach Millinillion. Repeat with those numbers to reach Billinillion. After that comes a Trillinillion, Quadrillinillion, Quintillinillion, Sextillinillion, Septillinillion, Octillinillion, Nonillinillion, and on...
A googol, officially known as ten-duotrigintillion or ten thousand sexdecillion, is a 1 with one hundred zeros after it. Written out, a googol looks like this: 10,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000.
Googolplex may well designate the largest number named with a single word, but of course that doesn't make it the biggest number. In a last-ditch effort to hold onto the hope that there is indeed such a thing as the largest number… Child: Infinity! Nothing is larger than infinity!
Everyone loves to pull out infinity, or the fabled “infinity plus one.” Maybe if you were inclined to do so, you pulled out the googol or the googolplex. Smaller than infinity, but really big numbers each. But as you probably figured, infinity doesn't really count.
A millillion (alternately millinillion, milliatillion or milletillion) is equal to 103,003 in the short scale, or 106,000 in the long scale (this number is also called Platillion). It is made by combining "mille" (1,000) with the standard -illion suffix, which is itself derived from "mille".
There's quadrillion, quintillion, sextillion, septillion, octillion, nonillion, decillion and more. Each is a thousand of the previous one. There's even a humongous number called vigintillion, a one with 63 zeros. But vigintillion is a shrimp compared to a googol.
Written out in ordinary decimal notation, it is 1 followed by 10100 zeroes; that is, a 1 followed by a googol of zeroes.
