Convert MB to GB

Please provide values below to convert megabyte [MB] to gigabyte [GB], or vice versa.

Definition: A megabyte (symbol: MB) is equal to 106 bytes (10002 bytes), where a byte is a unit of digital information that consists of eight bits (binary digits).

History/origin: The megabyte is based on the byte, which is derived from the bit, and is a unit that makes use of SI (International System of Units) prefixes. The prefix "mega" can be ambiguous; the SI use of "mega" would indicate that a megabyte is 1,000,000 bytes, or 10002 bytes, but a base of 1024 (rather than 1000) is also used in information technology as a convenient way to express byte multiples as powers of 2. In 1998, the International Electrotechnical Commission attempted to address this by defining new prefixes to indicate a base of 1024 rather than 1000. Rather than using the prefix "mega," within this system of prefixes, 10242 is referred to as a mebibyte.

Current use: Megabytes are widely used in data storage for file sizes (documents, photos, videos, etc.) as well as for storage devices such as flash drives or, in the past, floppy disks. Today however, storage devices are typically larger, often involving either gigabytes (10003 bytes) or terabytes (10004) of data.

Definition: A gigabyte (symbol: GB) is equal to 109 bytes (10003 bytes), where a byte is a unit of digital information that consists of eight bits (binary digits).

History/origin: The gigabyte is based on the byte, which is derived from the bit, and is a unit that makes use of SI (International System of Units) prefixes. The gigabyte is most commonly understood in terms of its decimal definition of 10003 bytes. There is also however, a binary definition where a gigabyte is 10243 bytes. Because this can be the source of confusion, in 1998, the International Electrotechnical Commission published standards that required the gigabyte strictly denote 10003 bytes. Prefixes to denote the byte being based on 1024 rather than 1000 were also created, with gibibyte referencing 10243 bytes. Despite this effort, the gigabyte is still often used to signify either of these definitions.

Current use: The unit of bytes and all its multiples are used worldwide for data storage. Computer files, hard disks, Blu-ray discs, video games, etc. all store or contain storage space referenced in byte multiples such as kilobytes, megabytes, or gigabytes.

1 MB = 0.0009765625 GB1 GB = 1024 MB

Example: convert 15 MB to GB:15 MB = 15 × 0.0009765625 GB = 0.0146484375 GB
