Scientifically, a quintillion can be represented as 1 Quintillion = 1 × 10^{18}
Important Notes:
A quintillion can be expressed as a product of the following numbers.
 1 million × 1 million × 1 million (or) 1,000,000 × 1,000,000 × 1,000,000 = 1,000,000,000,000,000,000 (million million millions)
 1 billion × 1 billions = 1,000,000,000 × 1,000,000,000 = 1,000,000,000,000,000,000 (billion billions)
 1 million × 1 trillion = 1,000,000 × 1,000,000,000, 000 = 1,000,000,000,000,000,000 (million trillions)
 1 trillion × 1 million = 1,000,000,000, 000 × 1,000,000 = 1,000,000,000,000,000,000 (trillion millions)
The prefix 'exa' can be added to make a quantity as "quintillion". For example.
 Exabytes means Quintillion bytes.
 Exameter means Quintillion meters.

Solved Examples on Quintillion

Example 1 : How many quintillions is 5,000,000 x 5,000,000 x 1,000,000?
Solution:The product of the given numbers is 25,000,000,000,000,000,000. We know that 1 quintillion is 10^{18 } . Therefore, the given number is 25 quintillion.
The product of the given numbers is 25 quintillion. 
Example 2: About 2.5 quintillion bytes of data is being generated daily. What is its equivalent in million bytes?
Solution:We know that 1 million is 10^{6} and 1 quintillion is 10^{18}. Therefore, there are a million million millions in a quintillion. Therefore, 2.5 quintillions = 2,500,000,000,000 millions.
