When kids “dare” each other, the level of the dare quickly increases. A dare will become a double-dare, then a triple-dare, and then… something like a “20 million, billion, trillion zillion gazillion dare.” Why? They don’t know what comes after a Trillion? Do you?

## What Are Named Numbers?

Named numbers are number increments so big that they have their own name. For example, Millions, Billions, and Trillions are all named numbers.

## How Much Is A Trillion Dollars?

A Trillion is a very large number, especially when you’re counting money. You’d need several warehouses just to store a Trillion dollars in United States currency. Oh, to be a Trillionaire and have to deal with these types of silly problems.

But anyone can be a Zimbabwe Trillionaire! You can (eBay link) (eBay link) (eBay link) (eBay link)(eBay link) buy a one hundred trillion dollar bill in Zimbabwe currency for about $1+ USD on eBay! But what comes after a Trillion dollars?

## What Named Number Comes After Trillion?

The next *named number* after a Trillion is a *Quadrillion*. You’d need a bank the size of a large city just to store all of that cash!

In case you aren’t keeping track, the named number order so far is Million, Billion, Trillion, and Quadrillion. But what comes after a Quadrillion? Keep reading to find out.

## How Many Billions Are In A Quadrillion?

A billion is 1,000,000,000 (1 followed by 9 zeros) and a quadrillion is 1,000,000,000,000,000 (1 followed by 15 zeros). There are 1,000 billions in a trillion. So, there would be one thousand trillions in a quadrillion. After 999 thousand comes one million. After 999 million comes one billion. After 999 billion comes one trillion. Etc…

To calculate a quadrillion, you can divide the number of zeros in a quadrillion by the number of zeros in a billion. In this case, 15 zeros divided by 9 zeros equals approximately 1,667 billions.

## Names Of Large Numbers Chart

While a Million, a Billion and a Trillion are all large numbers, they are tiny compared to massive numbers like a Vigintillion or Googolplex. Here’s a “names of large numbers chart” below that lists the names of large numbers in order with their scientific notations. Each new number on this list increases the power of 10 by three or more. How many of these large number names do you recognize?

### What Does A Trillion Dollars Look Like?

The United States is several TRILLION dollars in debt! But exactly what does a trillion dollars look like?

## How Much Is Zillion?

Is a Zillion a real number? No. Even though the word “zillion” is frequently used in pop culture, a *Zillion* is not a real number. It was just made up by people who don’t know what comes after a Trillion.

Zillion, jillion, and gazillion are all made-up words.

## How Big Is A Google? (How Big Is A Googol?)

A “**Google**” isn’t a real number. The search engine Google got the inspiration for their name from the number Googol. They just decided to spell it differently. So, when someone wants to know the answer to “How big is Google?”, they probably mean how big is a Googol?

A Googol is a massive number. It is written as the number one followed by 100 zeros.It 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

## How Many Zeros In A Googolplex?

How big is a Googolplex? If we are talking about the large number and not the Googleplex building where Google is headquartered, the number Googgoplex is the number 1 followed by 10^100 zeros based on the international number system.

The number is so big that a piece of paper spanning the width of the entire Universe wouldn’t be big enough. Some higher-level mathematics experts even theorize that a Googolplex is bigger than all the atoms in the Universe. It’s so big that there’s currently no known use for it yet in mathematics.

**NERD NOTE:** Although infinity denotes endlessness, not an actual number. For all practical purposes, a Googolplex and all large numbers bigger than a Googolplex are essentially equal to infinity.

## How Long Would It Take To Count To A Googol Or A Googolplex?

If you’re wondering how long it would take to count to a Googol, there’s not much of a point. Just counting to a Trillion would take over 30,000 years.

Even trying to think about counting to a Googolplex is just crazy. A Googolplex is so much bigger than a Googol, it’s impossible to even write it down in decimal notation.

But if you were to count at a rate of one number per second, it would take you over 31 billion years to just reach a Googol. Sadly, that’s 18 billion years too late for the age of our Universe, which is estimated to die in 13.8 billion years. Also, our Sun will expand into a red giant in about 5 billion years and swallow the Earth and other inner planets. So you’ll need to do your counting while adrift in deep space. Eventually, black holes will consume all matter in the Universe and then finally evaporate, but you’d still be counting. Have fun!

## What Is The Largest Known Number In Existence?

Throughout the centuries, people have tried to prove that their integer is greater than others, even though there are more numbers than atoms in the Universe. The biggest known number referred to regularly is a Googolplex, which works out as 1010^100.

But, mathematicians love to invent numbers with large values and give them their own names. For example, mathematician **Stanley Skewes** named a number even bigger than Googolplex, called **Skewes’ Number**. However, **Graham’s Number** is currently considered to be the world’s largest known number. In fact, Graham’s Number is so big that it can’t be written with conventional notation.

## What Number Comes After A Trillion? – A Quadrillion!

So, what comes after a Trillion? Now you know the answer. It’s a Quadrillion! Just imagine being a Quadrillionaire! What would you do with all of that money? Where would you keep it?

Wow, I had no idea that there were even numbers beyond a trillion! This is fascinating. I always thought that a trillion was the biggest number there was. Thanks for sharing this interesting post!

Leon

im going to memorize as many of these as possible! great bar trivia questions!

“There are one thousand billions in a quadrillion”

No. There are one thousand billions in a trillion. So there would be one thousand trillions in a quadrillion. After 999 thousand comes one million. After 999 million comes one billion. After 999 billion comes one trillion. Etc…

buena lista… me hace pensar.

Oops! I thought a “zillion” was a real number.
