Equal to 1024^2 bytes
(Binary Unit)

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

MiB = GB x 10003 / 10242

Note : Here we are converting the units between different standards. The source unit Gigabyte is Decimal where as the target unit Mebibyte is Binary. In such scenario, first we need to convert the source unit to the basic unit - Byte - multiply with 1000^3, and then convert to target unit by dividing with 1024^2 .

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


Mebibyte = Gigabyte x 10003 / 10242


Mebibyte = Gigabyte x (1000x1000x1000) / (1024x1024)


Mebibyte = Gigabyte x 1000000000 / 1048576


Mebibyte = Gigabyte x 953.67431640625

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

  1. = 10 x 10003 / 10242
  2. = 10 x (1000x1000x1000) / (1024x1024)
  3. = 10 x 1000000000 / 1048576
  4. = 10 x 953.67431640625
  5. = 9536.7431640625
  6. i.e. 10 GB is equal to 9,536.7431640625 MiB.

(Result rounded off to 40 decimal positions.)

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

Definition : Mebibyte

A Mebibyte (MiB) is a binary unit of digital information that is equal to 1,048,576 bytes (or 8,388,608 bits) and is defined by the International Electro technical Commission(IEC). The prefix "mebi" is derived from the binary number system and it is used to distinguish it from the decimal-based "megabyte" (MB). It is widely used in the field of computing as it more accurately represents the amount of data storage and data transfer in computer systems.
