A zillion is a huge but nonspecific number.

Zillion sounds like an actual number because of its similarity to billion, million, and trillion, and it is modeled on these real numerical values.

However, like its cousin jillion, zillion is an informal way to talk about a number that’s enormous but indefinite.

## How many zeros are in a zillion?

Zi-llion = 10^[3*(Zi + 1)]. Therefore, a zillion has 3*(Zi + 1) zeroes! Why is the first number (ten) made from digits 1 and 0 not by others?

## Is there such thing as zillion?

No such thing as a zillion – but what’s after a trillion? After a trillion comes a trillion and one, and so on and so forth, until you get to a quadrillion, which has 15 zeros. Then is a quintillion, 18 zeros; a sextillion, 21 zeros; and on up to a centillion, which has 303 zeros.

## What number is after trillions?

Trillion is a 1 with 12 zeros after it, and it looks like this: 1,000,000,000,000. The next named number after trillion is quadrillion, which is a 1 with 15 zeros after it: 1,000,000,000,000,000.

## What is this number 1000000000000000000000000?

A thousand trillions is a quadrillion: 1,000,000,000,000,000.

## What is a Centillion?

In the American numeral system, the centillion is the number one followed by 303 zeros, and in the European system it is one followed by 600 zeros. The googol is one followed by 100 zeros and is far less than a centillion.

## What is the highest number?

A googol is a 1 with a hundred zeroes behind it. We can write a googol using exponents by saying a googol is 10^100. The biggest named number that we know is googolplex, ten to the googol power, or (10)^(10^100). That’s written as a one followed by googol zeroes.

## What comes after Centillion?

The googol is one followed by 100 zeros and is far less than a centillion. The googolplex, however, is one followed by a googol of zeros and is far in excess of a centillion. Well, after a Centillion comes Uncentillion.

## How much is a googolplex?

A googolplex is the number 10googol, or equivalently, 10. Written out in ordinary decimal notation, it is 1 followed by 10100 zeroes, that is, a 1 followed by a googol zeroes.
