The formula of converting the Zettabyte to Petabyte is represented as follows :

PB = ZB x 10002

Now let us apply the above formula and, write down the steps to convert from Zettabyte (ZB) to Petabyte (PB). This way, we can try to simplify and reduce to an easy to apply formula.


Petabyte = Zettabyte x 10002


Petabyte = Zettabyte x (1000x1000)


Petabyte = Zettabyte x 1000000

Example : If we apply the above Formula and steps, conversion from 10 ZB to PB, will be processed as below.

  1. = 10 x 10002
  2. = 10 x (1000x1000)
  3. = 10 x 1000000
  4. = 10000000
  5. i.e. 10 ZB is equal to 10,000,000 PB.

(Result rounded off to 40 decimal positions.)

You can use above formula and steps to convert Zettabyte to Petabyte using any of the programming language such as Java, Python or Powershell.
