What Comes After Trillion? Know about Large Numbers

Home » What Comes After Trillion? Know about Large Numbers

In general, reading large numbers in words is a challenging task. Moreover, the naming conventions for numerals also vary from each country. Hence, it is common for everyone to experience confusion on how to call big numbers. In general, most people will have an idea about million, billion, and trillion. But what comes after a trillion?

If you wish to know about a trillion and the names of other big numbers that come after a trillion, look at this blog and update your knowledge.

Here, we have shared interesting information about a trillion and what comes after a trillion.

What is a Trillion?

What Comes After Trillion

In the international number system, one trillion is written as 1,000,000,000,000, with the number “1” followed by 12 zeroes. Its mathematical notation is 1012. You can memorize it as 4 groups of 3 zeros following 1.

Usually, Americans and Europeans will call big numbers with different names. For instance, 1 000 000 000 000 is a billion for Europeans and a trillion for Americans. So, remember the names based on the location.

Why Do Americans and Europeans Call Big Numbers Differently?

Mainly because of their historical, cultural, and linguistic factors, the Americans and Europeans use different names for large numbers. In the entire globe, the majority of countries and languages have created their own naming system for numbers. Hence, the practice of calling big numbers with various names has emerged.

However, these differences are only noticeable when it comes to calling big numbers on the “long scale” used in many European countries and the “short scale” used in the United States and some other English-speaking nations.

Every new term in the so-called long scale is equivalent to a million times the previous term.  On the other hand, the short scale increases by a thousand with every additional term.

For instance, on the long scale, a billion is equal to a trillion on the short scale. On the other hand, a quintillion is equivalent to a trillion on the long scale.

Large numbers are named differently in different languages, and these linguistic differences have influenced number naming systems throughout several nations. For example, the long scale is used in French and Spanish-speaking nations, and this has impacted European number naming practices.

In international contexts, discrepancies in the naming of large numbers can create confusion. Therefore, to ensure clarity and consistency, international scientific and finance organizations use standardized notations or scientific notations (e.g., 10^12 or 1012 for a trillion).

The long scale is now more common in Europe, but not all countries use it, and there may be differences within regions. Meanwhile, the short scale is used in many English-speaking countries outside the United States, including Canada and Australia.

Names of Big Numbers in the Long and Short Scale

Would you like to know how to call numbers after a trillion? If yes, then take a look below. Here, we have shared the names of large numbers on the long and short scale.

In the Long Scale

  • Milliard = 1,000,000,000 (109)
  • Billion = 1,000,000,000,000 (1012)
  • Billiard = 1,000,000,000,000,000 (1015)
  • Trillion = 1,000,000,000,000,000,000 (1018)
  • Trilliard = 1,000,000,000,000,000,000,000 (1021)
  • Quadrillion = 1,000,000,000,000,000,000,000,000 (1024)

In the Short Scale

  • Billion = 1,000,000,000 (109)
  • Trillion = 1,000,000,000,000 (1012)
  • Quadrillion = 1,000,000,000,000,000 (1015)
  • Quintillion = 1,000,000,000,000,000,000 (1018)
  • Sextillion = 1,000,000,000,000,000,000,000 (1021)
  • Septillion = 1,000,000,000,000,000,000,000,000 (1024)

What Comes After a Trillion?

Some other big numbers that come after a trillion are a Zillion, Gazillion, or Prillion. But if we put words like mega in front of them, like “Mega-Million,” then they may sound very big. Generally, people use these phrases when they have no idea about the proper names for larger terms or what comes after trillion.

Remember, Zillion is not a real number. Especially, to identify extremely large undetermined numbers, people often use the term ‘Zillion’.

List of Names of Large Numbers

As listed above, next to trillion, comes quadrillion, quintillion, sextillion, and septillion. To know the names of the next numbers that come after septillion, look at the list below.

  • Octillion = 1027
  • Nonillion = 1030
  • Decillion = 1033
  • Undecillion = 1036
  • Duodecillion = 1039
  • Tredecillion = 1042
  • Quattuordecillion = 1045
  • Quindecillion = 1048
  • Sexdecillion = 1051
  • Septemdecillion = 1054
  • Octodecillion = 1057
  • Novemdecillion = 1060
  • Vigintillion = 1063
  • Unvigintillion (or vigintunillion) = 1066
  • Duovigintillion (or vigintiduoillion) = 1069
  • Trevigintillion (or vigintitrillion) = 1072
  • Quattuorvigintillion (or vigintiquadrillion) = 1075
  • Quinvigintillion (or vigintiquintrillion) = 1078
  • Sexvigintillion (or vigintisextillion) = 1081
  • Septvigintillion (or vigintiseptillion) = 1084
  • Octovigintillion (or vigintoctillion) = 1087
  • Nonvigintillion (or vigintinonillion) = 1090
  • Trigintillion = 1093
  • Untrigintillion = 1096
  • Duotrigintillion = 1099
  • Ten-duotrigintillion = googol = 10100
  • .
  • .
  • Skewer’s number = 10130
  • .
  • .
  • Centillion = 10303
  • .
  • .
  • Googolplex = (1010)100
  • .
  • .
  • Skewes’ Number: ((1010 )10 )34

The list above will help you remember what comes after a trillion. Note that, to write 1027, you should add 1 followed by 27 zeroes. Similar to this pattern, every new number to the power of 10 should be written. To write the number centillion, use 100 groups of 3 zeros beyond 1000. It follows the American convention for naming numerals.

What is a Googol?

One googol is a mathematical term that represents one followed by 100 zeros.

The term “googol” was coined by the American mathematician Edward Kasner in the early twentieth century, when he asked his nine-year-old nephew, Milton Sirotta, to come up with a name for this enormous number. The word “googol” sprang from the child’s imagination.

Several literatures state that Googol is one of the biggest numbers humans have ever identified. To put a googol into perspective, the visible Universe is thought to contain approximately 1080 atoms. A googol, on the other hand, is far larger, reflecting the breadth of mathematical concepts and the scale of numbers that mathematicians may use in theoretical and scientific contexts.

What is a Googolplex?

The term “Googolplex” refers to a mathematical notion based on the famous googol name. But it’s even larger.

A googolplex is defined as 10 to the power of a googol, or 1 followed by a googol amount of zeros. The number googolplex is so enormous that it outnumbers the number of particles in the visible universe, making it nearly impossible to represent or work in any physical way.

Know About Skews’ Number

Skewes’ number is one of the largest numbers, surpassing even the googolplex. It is thought to be the highest number ever used in a mathematical proof. Mathematician Stanley Skewes created this number, which is named after him.

Skewes’ number is 10 to the 10th to the 34th. Look at the mathematical representation for greater clarity: Skewer’s number equals 1 x 10130.

Skewes was particularly interested in prime numbers. Skewes’ number was created in 1933. One of his colleagues described it as the greatest number that has ever had a specific purpose in mathematics. The theory may not be true today.

Understand Graham’s Number

As previously stated, Skewes’ number may not be as relevant now. Skewes’ number has gradually lost its distinctiveness with Graham’s number.

Graham’s number is currently treated as the world’s biggest number. Graham’s number cannot be written using ordinary notation because it is so enormous. It got its name after mathematician R.L. Graham, who first exposed it to the public.

Graham’s number is thought to be so huge that we couldn’t write it even if we transformed all of the matter in the universe into pens and ink. It still won’t be enough to write down Graham’s phone number.
