We talked about large numbers in our last blog, including a million, a billion, and a trillion. But is that all? Or there are larger numbers than a trillion? If yes, then **what comes after a trillion**? Not sure what is the number that comes after a trillion? Well! Don’t worry since we are here to help you with this. We will take a deep dive into all the possible numbers that come after a trillion in this blog. It will answer your question: **What comes after a trillion**?

So if you are interested in the names of other very large numbers that come after a trillion, you are at the right place. Hence, keep reading to learn **what comes after a trillion** and boost your knowledge further. By the end of this blog, you will know the names of every important number that is larger than a trillion. We will provide you with the easiest tricks and tips to remember the same. And since too much information can be overwhelming at times, we will take it one step at a time. Let’s start our journey to answer our question: **What comes after a trillion,** with the basic definition of trillion first?

**What is a Trillion? **

We are going to dictate the definition of trillion to refresh your knowledge. The first step towards answering **what comes after a trillion** is getting the basics right. It starts with understanding the definition of a trillion.

One trillion is written as 1,000,000,000,000 in which the number “1” is followed by 12 zeros. Its

Mathematical notation is 10^{12}. You can remember it as 4 groups of 3 zeros after the 1. And if you are wondering how many billions are there in a trillion, then take a look below.

**How Many Billions in a Trillion? **

Discussing how many billions are there in a trillion and refreshing your knowledge is important to answering **what comes after a trillion**.

- As we discussed in the definition of a trillion, one trillion is written as 1,000,000,000,000 in the International number system. It has 12 zeros after the 1.
- Also, we know that one billion is written as 1,000,000,000. It has 9 zeroes after the 1.
- If we multiply 1000 with one billion, the answer will be one trillion. See below:

One thousand × One Billion = One Trillion

1000 × 1,000,000,000 = 1,000,000,000,000

It means that there are one thousand billion in one trillion.

One trillion = One thousand billion

**How Many Billions in a Trillion: Quick Answer **

As we solved above and found that there are 1,000 million in a billion, we can say there are 1,000 billion in a trillion.

1,000,000,000 × 1,000 = 1,000,000,000,000

Now, let’s move ahead toward answering **what comes after a trillion**.

Don’t get confused by so many zeroes. Remember the tricks that we have discussed:

- Nine zeroes are in a billion (or three groups of three zeroes).
- There are 12 zeroes in a trillion (or four groups of three zeroes).

**How Many Crores in a Trillion? **

It is another important part of answering **what comes after a trillion**. In the given question, we need to convert a number from one number system to another.

**Here is the complete step-by-step answer: **

- As we discussed in the definition of a trillion, one trillion is written as 1,000,000,000,000 in the International number system. It has 12 zeros after the 1.
- We have to convert the number one trillion into the Indian number system.
- In the Indian number system, 1 crore is equal to 1,00,00,000. It has seven zeroes after the 1.
- To find out the number of crores in one trillion, we need to divide one trillion by one crore.

1000000000000/10000000 = 100000

Hence, we can see that after dividing one trillion by one crore, the answer is 1,00,000. It means that there is 1,00,000 crore in one trillion.

One trillion = Ten thousand crore

**How Big Are the Numbers That Come After a Trillion? **

Have you ever watched the TV show “Who Wants to Be a Millionaire?” Well, you don’t need to. But you need to imagine a TV show with the prize money in the form of a number that comes after a trillion. What would you call it? Have you ever wondered?

Or, let’s suppose you won a million dollars? How would you manage it? In most cases, large amounts won by people, such as a one million dollar lottery, are not given to them in one go. They are spread over the years, i.e., a long period. For one million, the usual duration is 20 years.

So, how much would it be if you won a trillion dollars? And what if someone asked you to count a trillion dollars one by one at a dollar a second? It will take you around 31,710 years. That’s how big a trillion is. You can imagine the number of years for **what comes after a trillion**.

Let’s take another example. Let’s say the government of a country spends three billion per day. At this rate, how much time will it take to spend a trillion dollars? Do the calculations and let us know in the comments below.

**What Comes After Trillion? **

Let’s find out **what comes after a trillion**. You must have heard someone say or use the words “zillion,” “gazillion,” “prillion,” etc. Maybe in movies, if not in real life. No?

Well, now you have. But the question is, what are these numbers. How to represent them mathematically? Can we use them in real life? We will answer all such questions in this blog section: **What comes after a trillion**? Zillion, gazillion, or prillion are quite large numbers. They can be even large if we use terms like mega in front of them, such as “Mega-Million.” People use these terms because they don’t know the proper names for bigger terms or **what comes after trillion**.

In our last blog, we discussed that we go from a million to a billion and then to a trillion. Now, after a trillion, there comes a number known as quadrillion, and then we have other numbers following it. These numbers are quintillion, sextillion, septillion, octillion, nonillion, and decillion. Take a look below to know **what comes after a trillion**.

**Understanding the List **

We hope this list will help you remember **what comes after a trillion**. In the list that we have created above, you can see that every number increases the power of 10 by three. What does it mean? To get a new number, you only need to add three extra zeros at the end of the number. As simple as that. You add three zeros in the future, and you will have a new number.

Let us try to understand this with an example.

- As you know, a billion is a 1 with nine zeros after it. We can write it as 1,000,000,000.
- The next number is a trillion. It has a 1 with twelve zeros after it. We can write it as 1,000,000,000,000.

See! We just added three zeros to one billion and got one trillion. You can follow the same pattern until you get to ten-duotrigintillionth. It is more commonly known as a Googol.

Fun Fact

Did you know that the search engine Google got its name from Googol?

We do not have names for the numbers between Googol, Skewer’s Number, Centillion, or Googolplex.

**Points to Remember **

To understand what comes after a trillion and all these large numbers, you need to keep a few points in your mind.

- We have not given any name to the numbers between Googol, Skewer’s number, centillion, and Googolplex.
- There is no global agreement about naming the large numbers or
**what comes after a trillion**. - It is written in many books that Googol is one of the largest numbers humans have ever named more recently; we also had new definitions about Skewer’s number. It is believed to be the largest number ever used in a mathematical proof.
- Then, the number centillion can be represented as 100 groups of 3 zeros beyond 1000. It follows the American convention of naming numbers.

We hope this list helps you understand **what comes after a trillion**. If you wonder why “zillion” is not a part of the list, then tell us that Zillion is not a real number. It is a term that people have made up the word Zillion to refer to an undetermined number extremely large in quantity.

**What Comes After Trillion: Quadrillion **

If you asked us for the immediate response to the question: **what comes after a trillion,** it would be quadrillion. As you can see, that number comes exactly after a trillion.

- We can define a quadrillion as 1 with 15 zeros after it.
- It can written as 1,000,000,000,000,000.
- You can remember it as 5 groups of 3 zeros after the 1.
- We can represent it in the mathematical form as 1×10
^{15}.

One quadrillion = 1×10^{15} = 1,000,000,000,000,000

Do We Need to Know What Comes After a Trillion?

Webster’s Dictionary talks about the differences between American and English numeration systems.

The list that we have created above is as per the American convention. There was no need for number names beyond millions until World War I. By that time, numbers could be expressed in powers of ten without needing to refer to them by any name.

The same reason goes for why:

- A billion is 1,000,000,000 in the United States.
- While in England it is 1,000,000,000,000.

But representing numbers in terms of zeros and powers of tens can be a lot to ask for. People often get confused between the number of zeros and the powers of ten. That is why having names for larger numbers seems like a good idea. We hope this helps in understanding **what comes after a trillion**.

#### What Comes After a Trillion: Understanding the Large Numbers

To this point, we have talked about many large numbers that come after a trillion. It was meant to answer our question: **what comes after a trillion**? We created a list to put the manes and mathematical representations of all the numbers. This list aims you remember these big terms with their scientific notations.

We have also covered all the focus points and tips you need to remember. Now, moving ahead on the quest to answer **what comes after a trillion**, we need to understand these terms in detail. Let us get started.

We are sure that you can easily see all the massive key numbers mentioned in the list above. But what do those numbers mean? How can you understand them so that you never forget them? Most people find it difficult to take in this information. Do not worry if you feel the same because we will break it down in a simpler language.

- It can be difficult to conceptualize such large numbers, but there are some tricks that we will share with you to help you get a general idea of just how large they are.
- Trillion is one of the smallest numbers (along with million and billion) on our list.
- But do not forget that it is still an incredibly large number.
- If we ask you to count to a trillion, you would most likely take 31,709 years to do so!

**What Comes After a Trillion: Googol**

Moving forward, we have googol as one of the largest numbers on the list. A googol is 1 with one hundred zeros after it. If you try writing it donw on a paper using a pen, it would look 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.

Count the zeros and let us know if we got that right.

**As you can tell by taking a look at the list: **

- A googol is also called Ten-duotrigintillionth.
- Its mathematical representation is 1 x 10
^{100}.

You must have heard your teachers say: write it down. It will help you remember it. They suggest it quite often because it is true. The same is the case with large numbers. You need to write a large number out. It will give you a better sense of how big it is. And then, you can compare it to its scientific notation, which appears to be very small since it is its contracted form.

**What Comes After a Trillion: Googolplex**

What about a googolplex? Well, as you can see, it is one of the massive numbers in the chart.

- A googolplex is a number which follows the 1a googol of zeros follows the 1a googol of zeros follows the 1a googol of zeros follows the 1a googol of zeros follows the 1.
- Its mathematical notation is 1x(10
^{10})^{100}

A googolplex is a very large number that comes way after a trillion. It is so large that there is no known use in math. Some mathematicians and astronomers even have some theories that the number googolplex is greater than the total number of atoms in the universe.

Try writing down the number googolplex.

**What Comes After a Trillion: Skewes’ Number **

What comes after googolplex? Is there any number? Or do the numbers end at googolplex? Let us find out. Some numbers come after googolplex, and we have named them too. Skewes’ number is one of the larger numbers than even a googolplex. This number was developed by mathematician Stanley Skewes and named after him.

We can define Skewes’ number as 10 to the 10th to the 34th. Please take a look at its mathematical representation for more clarity: Skewer’s number = 1 x 10^{130}

Skewes had a particular interest in prime numbers. Skewes’ number was introduced back in 1933. One of his colleagues defined it as the largest number that has ever served any definite purpose in mathematics. The theory may not stand true today.

**What Comes After a Trillion: Graham’s Number **

As we said, Skewes’ number may not hold the same relevance today. Over time, Skewes’ number has lost its distinction to Graham’s number.

Graham number is currently considered the world’s largest number. And since Graham’s number is a very large quantity, it cannot be written with conventional notation. The name of the number, i.e., Graham’s number, comes from mathematician R.L. Graham who introduced it to the world.

Graham’s number is considered to be so large that we can’t write it even if we converted all the matter in the universe into pens and ink. It still won’t be enough to write out Graham’s number.

**Summary: What Comes After Trillion? **

What is the number that comes after a trillion? That is the question we started in our discussion. This blog discussed all the possible numbers that come after a trillion.

The immediate response to the question: **what comes after a trillion **would be quadrillion since that is the number that comes exactly after a trillion. As discussed in our blog, a quadrillion can be defined as 1 with 15 zeros.

It can written as 1,000,000,000,000,000.

We have one quintillion, sextillion, septillion, octillion, and the list goes on till Graham’s number. It is a good idea to know and remember the names of large numbers. It can prove to be useful in many scenarios. For instance, if you are working with extremely large values or pursuing studies in higher-level mathematics.

As we discussed, the largest known number is Graham’s number at the moment. We do not know about tomorrow. It may change with the arrival of a new number. But for now, Graham’s number holds the position for the largest number ever known. Remember, it is too large and complicated that we can’t even write it down or conceptualize it, for that matter.

**Turito: Making Learning Fun **

Turito believes in making learning fun, especially for the kids. That is the key to keeping things in mind for a longer time. The more fun there is, the more you will learn. Last time, we discussed how many millions are there in a billion. In that blog, we touched on the definition of a trillion in one of the sections. Today, we talked about **what comes after a trillion**. We discussed all such numbers, their mathematical representations, and tips and tricks to remember them. We hope this blog helps you remember them!
