In our previous exploration of massive numbers, we journeyed through millions, billions, and trillions. But the numerical universe extends far beyond! You might be wondering, what comes after a trillion? Is that the end of the line for named numbers? Absolutely not! If you’re curious to discover the names of even larger numbers and expand your numerical horizons, you’ve come to the right place. Let’s delve into the fascinating world beyond the trillion and answer the question: What Comes After Quadrillion?
By the end of this exploration, you’ll be equipped with the knowledge of numbers that dwarf even trillions, along with handy tips to remember these colossal figures. We’ll take it step-by-step to avoid number overload. So, let’s begin our quest to understand what comes after a quadrillion by first revisiting the foundation: what exactly is a trillion?
Recap: What is a Trillion?
Let’s quickly refresh our understanding of a trillion to build a solid base for exploring even larger numbers. Understanding a trillion is the first step in answering what comes after a quadrillion.
A trillion is represented as 1,000,000,000,000. That’s a “1” followed by twelve zeros. In mathematical notation, it’s expressed as 1012. Think of it as four sets of three zeros after the initial one. And to put it in perspective, let’s recall how many billions make up a trillion.
Billions within a Trillion
Understanding the relationship between billions and trillions is crucial as we move towards what comes after a quadrillion.
- As we defined, a trillion is 1,000,000,000,000 in the international number system, boasting twelve zeros.
- A billion, on the other hand, is 1,000,000,000, with nine zeros following the one.
- Multiplying one billion by one thousand gives us one trillion:
One Thousand × One Billion = One Trillion
1000 × 1,000,000,000 = 1,000,000,000,000
Therefore, one trillion is composed of one thousand billions.
One trillion = One thousand billion
Quick Answer: Billions in a Trillion
To reiterate, and solidify our understanding before moving to what comes after a quadrillion, there are 1,000 billion in one trillion.
1,000,000,000 × 1,000 = 1,000,000,000,000
Don’t let all those zeros intimidate you! Remember the simple trick:
- A billion has nine zeros (three groups of three).
- A trillion has twelve zeros (four groups of three).
Crores in a Trillion: An Indian Perspective
For those familiar with the Indian number system, let’s bridge the gap and understand how many crores are in a trillion. This conversion is another way to grasp the magnitude before we tackle what comes after a quadrillion.
Here’s the step-by-step conversion:
- As established, one trillion is 1,000,000,000,000 in the international system, with 12 zeros.
- We’re converting to the Indian number system.
- In the Indian system, 1 crore equals 1,00,00,000, which has seven zeros.
- To find the number of crores in a trillion, divide one trillion by one crore:
1,000,000,000,000 / 10,000,000 = 100,000
Thus, one trillion equals 100,000 crore.
One trillion = One hundred thousand crore
The Immensity of Numbers Beyond Trillion
Imagine winning a million dollars – a life-changing sum for many. Lotteries often distribute such winnings over 20 years. Now, picture winning not just a million, but a trillion dollars! How long would it take to even count a trillion dollars, at one dollar per second? A staggering 31,710 years! That’s the sheer scale of a trillion, and numbers beyond, like what comes after a quadrillion, are even more mind-boggling.
Consider this: if a government spends three billion dollars daily, how long would it take to spend a trillion? Think about that while we explore even larger numbers!
Venturing Beyond Trillion: The Numerical Ladder
You might have heard terms like “zillion,” “gazillion,” or “prillion” – often in movies or casual conversation. But what are these really? Are they actual numbers? And what truly comes after a trillion in the world of defined numbers?
These “zillion” type words are informal terms for incredibly large, undefined quantities. People use them when they lack the precise names for truly enormous numbers, or when referring to what comes after quadrillion and beyond.
We know the sequence: million to billion to trillion. Now, directly after a trillion comes quadrillion. And it doesn’t stop there! Following quadrillion are quintillion, sextillion, septillion, octillion, nonillion, and decillion, and many more. Let’s unveil what comes after a quadrillion and the subsequent numerical giants:
- One million = 1×106
- One billion = 1×109
- One trillion = 1×1012
- One quadrillion = 1×1015
- One quintillion = 1×1018
- One sextillion = 1×1021
- One septillion = 1×1024

- …
- Skewes’ Number: ((1010)10)34
Decoding the Pattern of Large Numbers
This extensive list might seem daunting, but there’s a simple pattern to help you remember what comes after a quadrillion and beyond. Notice that each subsequent number increases the power of 10 by three.
Essentially, to get to the next number in the sequence, you just add three more zeros. It’s that straightforward! Each jump of three zeros signifies a move to the next “illion” number.
Let’s illustrate with an example:
- A billion (1,000,000,000) has nine zeros.
- A trillion (1,000,000,000,000) has twelve zeros.
See? We simply added three zeros to billion to reach trillion. This pattern continues as we ascend to what comes after quadrillion and further, at least up to ten-duotrigintillion, also famously known as a Googol.
Fun Fact: Did you know the search engine Google is named after Googol?
Beyond Googol, Skewer’s Number, Centillion, and Googolplex, the naming convention becomes less standardized, and gaps in named numbers exist.
Key Takeaways About Large Numbers
As we explore what comes after a quadrillion and these massive numbers, keep these points in mind:
- There aren’t universally agreed-upon names for every number between Googol, Skewer’s number, centillion, and Googolplex.
- Naming conventions for extremely large numbers lack global standardization.
- Googol was once considered one of the largest named numbers. Skewer’s number is notable as a very large number used in a mathematical proof.
- Centillion, following the American convention, represents 100 sets of three zeros beyond a thousand.
Hopefully, this clarifies what comes after a quadrillion and the landscape of truly large numbers! And if you were wondering about “zillion”—it’s not a formally defined number, but rather a placeholder for an immense, unspecified quantity.
Quadrillion: The Immediate Successor to Trillion
If you need a direct answer to what comes after a trillion, it’s quadrillion. It’s the number that immediately follows trillion in the sequence.
- A quadrillion is defined as 1 followed by 15 zeros.
- Written out, it’s 1,000,000,000,000,000.
- You can visualize it as five groups of three zeros after the initial 1.
- In mathematical notation: 1×1015.
One quadrillion = 1×1015 = 1,000,000,000,000,000
Why Bother with Numbers Beyond Trillion?
You might ask, why do we even need names for numbers beyond millions, let alone what comes after a quadrillion? Historically, until World War I, numbers beyond millions weren’t commonly needed in everyday life. Powers of ten could express most quantities without requiring specific names.
Interestingly, the definition of “billion” itself differs between American and British systems (though the American system is now largely adopted globally).
- In the United States, a billion is 1,000,000,000.
- Traditionally in England, a billion was 1,000,000,000,000 (now more commonly the American definition is used).
However, expressing very large numbers solely as powers of ten or strings of zeros can be cumbersome and prone to error. Having names for these numbers, like quadrillion and beyond, provides a more convenient and understandable way to communicate about them. This is especially true in fields like astronomy, finance, and advanced mathematics, and for simply understanding what comes after a quadrillion.
Understanding the Realm of Large Numbers
We’ve journeyed through numerous large numbers, all to answer the fundamental question: what comes after a quadrillion? We presented lists, notations, and patterns to aid in remembering these numerical giants.
But what do these numbers truly mean? How can we grasp their scale so they aren’t just abstract strings of digits? Visualizing such magnitudes is challenging, but we can use some tricks to get a sense of their enormity as we explore what comes after a quadrillion and beyond.
- Conceptualizing truly large numbers is difficult, but relatable examples can help.
- Trillion, while seemingly immense, is actually among the smaller numbers in our extended list.
- Yet, even a trillion is incredibly vast.
- Counting to a trillion would take approximately 31,709 years!
Googol: A Landmark in Large Numbers
Moving further up the scale, we encounter Googol, a truly massive number. A Googol is a 1 followed by one hundred zeros! Writing it out fully 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.
Take a moment to appreciate that string of zeros!
As our list indicates:
- Googol is also known as Ten-duotrigintillionth.
- Its mathematical form is 1 x 10100.
There’s a learning tip in understanding large numbers: write them out, or at least visualize writing them out. This exercise helps in appreciating their scale more than just seeing the compact scientific notation. It bridges the gap between the abstract notation and the sheer quantity they represent, especially when considering numbers far beyond what comes after a quadrillion.
Googolplex: Scaling to the Astronomical
Then there’s Googolplex, a number that dwarfs even Googol.
- A Googolplex is a 1 followed by a Googol zeros. Think about that for a moment!
- Its notation is 1x(1010)100.
Googolplex is so astronomically large it has no practical use in most mathematics. Some speculate that a Googolplex exceeds the total number of atoms in the observable universe! Trying to write out a Googolplex is practically impossible.
Skewes’ Number: A Number with a Purpose
Do numbers stop at Googolplex? No! There are numbers even larger. Skewes’ number is one such behemoth, exceeding even Googolplex. Developed by mathematician Stanley Skewes, it’s named in his honor.
Skewes’ number is defined as 10 to the power of 10 to the power of 34. In mathematical notation: Skewer’s number = 1 x 101034 (or sometimes represented as 10↑↑34 using Knuth’s up-arrow notation).
Skewes was researching prime numbers, and Skewes’ number, introduced in 1933, served a purpose in mathematical proof, once considered the largest number used in such a context.
Graham’s Number: The Current Record Holder
While Skewes’ number was once considered incredibly large for mathematical purposes, it has since been surpassed. Graham’s number currently holds the title of the “largest number practically used in mathematical proofs.”
Graham’s number is so immense it cannot be written in standard notation, or even in simple exponential notation like Skewes’ number. It arises from a specific problem in Ramsey theory and is named after mathematician R.L. Graham, who introduced it.
Graham’s number is beyond visualization. If you were to try and write it out, even if you converted all matter in the universe into pens and ink, you wouldn’t have enough resources to complete the task!
In Summary: What Comes After Trillion?
We started by asking: what is the number that comes after a trillion? This journey has taken us far beyond trillions, exploring a landscape of colossal numbers.
The direct answer to what comes after a trillion is quadrillion. A quadrillion is a 1 with 15 zeros (1,000,000,000,000,000).
From there, we ascend through quintillion, sextillion, septillion, octillion, and beyond, reaching into realms of numbers like Googol, Googolplex, Skewes’ number, and Graham’s number. Knowing these names is valuable, especially when dealing with extremely large quantities or pursuing advanced mathematics.
While Graham’s number is currently considered the largest “practical” number, the quest to define and understand ever-larger numbers continues. The numerical universe is vast and full of fascinating concepts that stretch the limits of human comprehension.
