Equal to 1024^3 bits
(Binary Unit)

The formula of converting the Megabit to Gibibit is represented as follows :

Gibit = Mbit x 10002 / 10243

Note : Here we are converting the units between different standards. The source unit Megabit is Decimal where as the target unit Gibibit is Binary. In such scenario, first we need to convert the source unit to the basic unit - Bit - multiply with 1000^2, 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 Megabit (Mbit) to Gibibit (Gibit). This way, we can try to simplify and reduce to an easy to apply formula.


Gibibit = Megabit x 10002 / 10243


Gibibit = Megabit x (1000x1000) / (1024x1024x1024)


Gibibit = Megabit x 1000000 / 1073741824


Gibibit = Megabit x 0.000931322574615478515625

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

  1. = 10 x 10002 / 10243
  2. = 10 x (1000x1000) / (1024x1024x1024)
  3. = 10 x 1000000 / 1073741824
  4. = 10 x 0.000931322574615478515625
  5. = 0.00931322574615478515625
  6. i.e. 10 Mbit is equal to 0.00931322574615478515625 Gibit.

(Result rounded off to 40 decimal positions.)

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

Definition : Megabit

A Megabit (Mb or Mbit) is a unit of digital information that is equal to 1,000,000 bits and it is commonly used to express data transfer speeds, such as the speed of an internet connection and to measure the size of a file. In the context of data storage and memory, the binary-based unit of mebibit (Mibit) is used instead.

Definition : Gibibit

A Gibibit (Gib or Gibit) is a unit of digital information that is equal to 1,073,741,824 bits and is defined by the International Electro technical Commission(IEC). The prefix "gibi" is derived from the binary number system and it is used to distinguish it from the decimal-based "gigabit" (Gb). 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.
