ZB to GiB - Conversion Formula and Steps

Zettabyte and Gibibyte are units of digital information used to measure storage capacity and data transfer rate. Zettabyte is a decimal standard unit where as Gibibyte is binary. One Zettabyte is equal to 1000^7 bytes. One Gibibyte is equal to 1024^3 bytes. There are 0.000000000001073741824 Zettabytes in one Gibibyte. - view the difference between both units

Zettabyte (ZB)
Equal to 1000^7 bytes
(Decimal Unit)
Gibibyte (GiB)
Equal to 1024^3 bytes
(Binary Unit)

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

GiB = ZB x 10007 / 10243

Note : Here we are converting the units between different standards. The source unit Zettabyte is Decimal where as the target unit Gibibyte 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 1024^3 .

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


Gibibyte = Zettabyte x 10007 / 10243


Gibibyte = Zettabyte x (1000x1000x1000x1000x1000x1000x1000) / (1024x1024x1024)


Gibibyte = Zettabyte x 1000000000000000000000 / 1073741824


Gibibyte = Zettabyte x 931322574615.478515625

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

  1. = 10 x 10007 / 10243
  2. = 10 x (1000x1000x1000x1000x1000x1000x1000) / (1024x1024x1024)
  3. = 10 x 1000000000000000000000 / 1073741824
  4. = 10 x 931322574615.478515625
  5. = 9313225746154.78515625
  6. i.e. 10 ZB is equal to 9,313,225,746,154.78515625 GiB.

(Result rounded off to 40 decimal positions.)

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