How many zeros are there in a quintillion?

A quintillion is a large number that is equal to 1 followed by 18 zeros. To write it out numerically, a quintillion looks like this:

1,000,000,000,000,000,000

In the United States and most parts of the world that use the short scale, quintillion represents 10¹⁸. The term ‘quintillion’ is derived from the Latin word ‘quintus,’ which means ‘fifth,’ indicating that it is the fifth power of a thousand.

Here’s how the number is structured:

• The first three zeros represent the thousands (1,000).
• The next three represent the millions (1,000,000).
• The following three represent the billions (1,000,000,000).
• The next three signify the trillions (1,000,000,000,000).
• Finally, the last three zeros complete the quintillion (1,000,000,000,000,000,000).

In summary, if you ever come across the term quintillion, remember that it’s a whopping number built from a simple 1 followed by 18 zeros!
