ZiB to PB - Conversion Formula and Steps

Zebibyte and Petabyte are units of digital information used to measure storage capacity and data transfer rate. Zebibyte is a binary standard unit where as Petabyte is decimal. One Zebibyte is equal to 1024^7 bytes. One Petabyte is equal to 1000^5 bytes. There are 0.0000008470329472543003390683225006796419 Zebibytes in one Petabyte. - view the difference between both units

Zebibyte (ZiB)
Equal to 1024^7 bytes
(Binary Unit)
Petabyte (PB)
Equal to 1000^5 bytes
(Decimal Unit)

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

PB = ZiB x 10247 / 10005

Note : Here we are converting the units between different standards. The source unit Zebibyte 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 - Byte - multiply with 1024^7, and then convert to target unit by dividing with 1000^5 .

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


Petabyte = Zebibyte x 10247 / 10005


Petabyte = Zebibyte x (1024x1024x1024x1024x1024x1024x1024) / (1000x1000x1000x1000x1000)


Petabyte = Zebibyte x 1180591620717411303424 / 1000000000000000


Petabyte = Zebibyte x 1180591.620717411303424

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

  1. = 10 x 10247 / 10005
  2. = 10 x (1024x1024x1024x1024x1024x1024x1024) / (1000x1000x1000x1000x1000)
  3. = 10 x 1180591620717411303424 / 1000000000000000
  4. = 10 x 1180591.620717411303424
  5. = 11805916.20717411303424
  6. i.e. 10 ZiB is equal to 11,805,916.20717411303424 PB.

(Result rounded off to 40 decimal positions.)

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

Conversion Units

Definition : Zebibyte

A Zebibyte (ZiB) is a unit of digital information that is equal to 1,180,591,620,717,411,303,424 bytes (or 9,444,732,965,739,290,427,392 bits) and is defined by the International Electro technical Commission(IEC). The prefix "zebi" is derived from the binary number system and it is used to distinguish it from the decimal-based "zettabyte" (ZB). It is widely used in the field of computing as it more accurately represents the storage size of high end servers and data storage arrays.

Python Code for ZiB to PB Conversion

You can use below code to convert any value in Zebibyte to Petabyte in Python.

zebibyte = int(input("Enter Zebibyte: "))
petabyte = zebibyte * (1024*1024*1024*1024*1024*1024*1024) / (1000*1000*1000*1000*1000)
print("{} Zebibyte = {} Petabyte".format(zebibyte,petabyte))

The first line of code will prompt the user to enter the Zebibyte as an input. The value of Petabyte is calculated on the next line, and the code in third line will display the result.
