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

1. = 10 x 1000
2. = 10000
3. i.e. 10 GB is equal to 10,000 MB.

(Result rounded off to 40 decimal positions.)

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

#### Definition : Gigabyte

A Gigabyte (GB) is a unit of digital information that is equal to 1,000,000,000 bytes (or 8,000,000,000 bits) and commonly used to measure the storage capacity of computer hard drives, flash drives, and other digital storage devices. It is also used to express data transfer speeds and in the context of data storage and memory, the binary-based unit of Gibibyte (GiB) is used instead.

#### Definition : Megabyte

A Megabyte (MB) is a unit of digital information that is equal to 1,000,000 bytes (or 8,000,000 bits) and commonly used to express the size of a file or the amount of memory used by a program. It is also used to express data transfer speeds and in the context of data storage and memory, the binary-based unit of mebibyte (MiB) is used instead.
