(Decimal Unit)

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

PB = Pibit x 10245 / (8x10005)

Note : Here we are converting the units between different standards. The source unit Pebibit is Binary where as the target unit Petabyte is Decimal. In such scenario, first we need to convert the source unit to the basic unit - Bit - multiply with 1024^5, and then convert to target unit by dividing with 8x1000^5 .

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


Petabyte = Pebibit x 10245 / (8x10005)


Petabyte = Pebibit x (1024x1024x1024x1024x1024) / (8x1000x1000x1000x1000x1000)


Petabyte = Pebibit x 1125899906842624 / 8000000000000000


Petabyte = Pebibit x 0.140737488355328

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

  1. = 10 x 10245 / (8x10005)
  2. = 10 x (1024x1024x1024x1024x1024) / (8x1000x1000x1000x1000x1000)
  3. = 10 x 1125899906842624 / 8000000000000000
  4. = 10 x 0.140737488355328
  5. = 1.40737488355328
  6. i.e. 10 Pibit is equal to 1.40737488355328 PB.

(Result rounded off to 40 decimal positions.)

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