## PB to ZiB - Conversion Formula and Steps

Petabyte and Zebibyte are units of digital information used to measure storage capacity and data transfer rate. Petabyte is a decimal standard unit where as Zebibyte is binary. One Petabyte is equal to 1000^5 bytes. One Zebibyte is equal to 1024^7 bytes. There are 1,180,591.620717411303424 Petabytes in one Zebibyte. - view the difference between both units Source Data UnitTarget Data Unit

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

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

ZiB = PB x 10005 / 10247

Note : Here we are converting the units between different standards. The source unit Petabyte 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 1000^5, 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 Petabyte (PB) to Zebibyte (ZiB).

1. STEP 1 → Zebibyte = Petabyte x 10005 / 10247
2. STEP 2 → Zebibyte = Petabyte x (1000x1000x1000x1000x1000) / (1024x1024x1024x1024x1024x1024x1024)
3. STEP 3 → Zebibyte = Petabyte x 1000000000000000 / 1180591620717411303424
4. STEP 4 → Zebibyte = Petabyte x 0.0000008470329472543003390683225006796419

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

1. = 10 x 10005 / 10247
2. = 10 x (1000x1000x1000x1000x1000) / (1024x1024x1024x1024x1024x1024x1024)
3. = 10 x 1000000000000000 / 1180591620717411303424
4. = 10 x 0.0000008470329472543003390683225006796419
5. = 0.000008470329472543003390683225006796419
6. i.e. 10 PB is equal to 0.000008470329472543003390683225006796419 ZiB.

(Result rounded off to 40 decimal positions.)

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

#### Definition : Petabyte

A Petabyte (PB) is a unit of digital information that is equal to 1,000,000,000,000,000 bytes (or 8,000,000,000,000,000 bits) and commonly used to measure the storage capacity of enterprise storage arrays and data centers. It is also used to express data transfer speeds and in the context of data storage and memory, the binary-based unit of Pebibyte (PiB) is used instead.

#### 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.
