ZB to ZiB - Conversion Formula and Steps

Zettabyte and Zebibyte are units of digital information used to measure storage capacity and data transfer rate. Zettabyte is a decimal standard unit where as Zebibyte is binary. One Zettabyte is equal to 1000^7 bytes. One Zebibyte is equal to 1024^7 bytes. There are 1.180591620717411303424 Zettabytes in one Zebibyte. - view the difference between both units

(Decimal Unit)
Zebibyte (ZiB)
Equal to 1024^7 bytes
(Binary Unit)

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

ZiB = ZB x 10007 / 10247

Note : Here we are converting the units between different standards. The source unit Zettabyte is Decimal where as the target unit Zebibyte is Binary. In such scenario, first we need to convert the source unit to the basic unit - Byte - multiply with 1000^7, and then convert to target unit by dividing with 1024^7 .

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


Zebibyte = Zettabyte x 10007 / 10247


Zebibyte = Zettabyte x (1000x1000x1000x1000x1000x1000x1000) / (1024x1024x1024x1024x1024x1024x1024)


Zebibyte = Zettabyte x 1000000000000000000000 / 1180591620717411303424


Zebibyte = Zettabyte x 0.8470329472543003390683225006796419620513

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

  1. = 10 x 10007 / 10247
  2. = 10 x (1000x1000x1000x1000x1000x1000x1000) / (1024x1024x1024x1024x1024x1024x1024)
  3. = 10 x 1000000000000000000000 / 1180591620717411303424
  4. = 10 x 0.8470329472543003390683225006796419620513
  5. = 8.470329472543003390683225006796419620513
  6. i.e. 10 ZB is equal to 8.470329472543003390683225006796419620513 ZiB.

(Result rounded off to 40 decimal positions.)

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

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 ZB to ZiB Conversion

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

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

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