GiB to GB - Conversion Formula and Steps

Gibibyte and Gigabyte are units of digital information used to measure storage capacity and data transfer rate. Gibibyte is a binary standard unit where as Gigabyte is decimal. One Gibibyte is equal to 1024^3 bytes. One Gigabyte is equal to 1000^3 bytes. There are 0.931322574615478515625 Gibibytes in one Gigabyte. - view the difference between both units

(Binary Unit)
Gigabyte (GB)
Equal to 1000^3 bytes
(Decimal Unit)

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

GB = GiB x 10243 / 10003

Note : Here we are converting the units between different standards. The source unit Gibibyte 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 1024^3, and then convert to target unit by dividing with 1000^3 .

Now let us apply the above formula and, write down the steps to convert from Gibibyte (GiB) to Gigabyte (GB).

  1. STEP 1 → Gigabyte = Gibibyte x 10243 / 10003
  2. STEP 2 → Gigabyte = Gibibyte x (1024x1024x1024) / (1000x1000x1000)
  3. STEP 3 → Gigabyte = Gibibyte x 1073741824 / 1000000000
  4. STEP 4 → Gigabyte = Gibibyte x 1.073741824

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

  1. = 10 x 10243 / 10003
  2. = 10 x (1024x1024x1024) / (1000x1000x1000)
  3. = 10 x 1073741824 / 1000000000
  4. = 10 x 1.073741824
  5. = 10.73741824
  6. i.e. 10 GiB is equal to 10.73741824 GB.

(Result rounded off to 40 decimal positions.)

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