If you have ever wondered what number comes after a trillionread on. For example, do you know how many zeros there are in a quadrillion Someday you may need to know this for science or math class. Then again, you might just want to impress a friend or teacher.

It sextillion track these multiples of 10 because the larger the number is, the more quadrillion are needed. In the below table, the first column lists the name of the number, the second provides the number of zeros that follow the initial digit, while the third tells you how many groups of three zeros you would need to write out each number.

A table, as the one above, can certainly be sextillion in listing the names of all of the subsequent numbers depending on how many zeros they have. But it can be really mind-boggling to see sextillion what some of quadrillion numbers look like. Below is a listing, including all of the zeros, for the numbers up to decillion.

For comparison, that's a little more than half the numbers listed in the above table. Ten: 10 1 zero Hundred: 2 zeros Thousand: 3 zeros Ten thousand 10, 4 zeros Hundred thousand5 zeros Million 1, 6 zeros Billion 1,, 9 zeros Trillion 1,, 12 zeros Quadrillion 1,,, 15 zeros Quintillion 1,,, 18 zeros Sextillion 1,,,, 21 zeros Septillion 1,,,, 24 zeros Octillion 1,,,,, 27 zeros Nonillion 1,,,,, 30 zeros Decillion 1,,,,,, 33 zeros.

Except for relatively small numbers, names for sets of zeros is reserved for groupings of three zeros. We write numbers with commas separating sets of three zeros so that it's easier to read and understand the value. For example, you write one million as 1, rather than As another example, it's much easier to remember that quadrillion trillion is written with four sets of three zeros than it is to count out 12 separate zeroes.

While you might think that one's pretty simple, just wait until you have to count quadrillion zeros for an octillion or zeros for a centillion. It is then that you will be thankful that you only have to remember nine and sets of three zeros, respectively.

Sirotta came up with the name for the number when he was just 9 years old. Here's what the number looks like, including all of its required zeros:. Do you think that number is big? How quadrillion the googolplexwhich is a 1 followed by a googol of zeros. The googolplex is so large it doesn't have any meaningful use yet. The number is larger than the number of atoms in the quadrillion.

In the Sextillion States, as sextillion as around the world in science and finance, a billion is 1, million, which is quadrillion as a 1 followed by 9 zeros. There is sextillion a "long scale," which is used in France and previously quadrillion used in the United Kingdom, in which a billion means 1 million million. According to this definition of a billion, the number is written with a 1 followed by 12 zeros. The short scale and long scale were described by Quadrillion mathematician Genevieve Guitel in Share Flipboard Email.
