PiB to GB Formula and Manual Conversion Steps

Pebibyte and Gigabyte are units of digital information used to measure storage capacity and data transfer rate. Pebibyte is a binary standard unit where as Gigabyte is decimal. One Pebibyte is equal to 1024^5 bytes. One Gigabyte is equal to 1000^3 bytes. There are 0.0000008881784197001252323389053344726562 Pebibytes in one Gigabyte.

Equal to 1000^3 bytes
(Decimal Unit)

The formula of converting the Pebibyte to Gigabyte is represented as follows :

GB = PiB x 10245 / 10003

Note : Here we are converting the units between different standards. The source unit Pebibyte is Binary where as the target unit Gigabyte is Decimal. In such scenario, first we need to convert the source unit to the basic unit - Byte - multiply with 1024^5, and then convert to target unit by dividing with 1000^3 .

Now let us apply the above formula and see how to manually convert Pebibyte (PiB) to Gigabyte (GB). We can further simplify the formula to ease the calculation.


Gigabyte = Pebibyte x 10245 / 10003


Gigabyte = Pebibyte x (1024x1024x1024x1024x1024) / (1000x1000x1000)


Gigabyte = Pebibyte x 1125899906842624 / 1000000000


Gigabyte = Pebibyte x 1125899.906842624

If we apply the above Formula and steps, conversion from 1 PiB to GB, will be processed as below.

  1. = 1 x 10245 / 10003
  2. = 1 x (1024x1024x1024x1024x1024) / (1000x1000x1000)
  3. = 1 x 1125899906842624 / 1000000000
  4. = 1 x 1125899.906842624
  5. = 1125899.906842624
  6. i.e. 1 PiB is equal to 1,125,899.906842624 GB.

(Result rounded off to 40 decimal positions.)
