Convert Megabytes (MB) to Gigabytes (GB)
Megabytes and gigabytes are standard units for measuring digital storage capacity. Using the decimal (SI) standard, 1 gigabyte equals 1,000 megabytes. This converter helps you quickly determine file sizes, storage requirements, and data usage when working with different scales of digital information.
Conversion Formula
Reverse: MB = GB × 1000

Unit Definitions
What is a Megabyte (MB)?
A megabyte is a unit of digital information equal to 1,000,000 bytes (10^6 bytes) in the decimal (SI) standard, or 1,048,576 bytes (2^20 bytes) in the binary standard.
History
The term megabyte came into use in the 1960s as computer storage grew beyond kilobytes. Early usage was inconsistent, sometimes meaning 1,000,000 bytes and other times 1,048,576 bytes. In 1998, the International Electrotechnical Commission introduced 'mebibyte' (MiB) for the binary value to reduce ambiguity.
Current Use
Megabytes are commonly used to describe file sizes for documents, images, and songs. A typical high-resolution photo is 3-8 MB, and a four-minute MP3 song is about 4 MB.
What is a Gigabyte (GB)?
A gigabyte is a unit of digital information equal to 1,000,000,000 bytes (10^9 bytes) in the decimal (SI) standard, or 1,073,741,824 bytes (2^30 bytes) in the binary standard.
History
The term gigabyte emerged in the 1980s as hard drives and storage media grew in capacity. Like the megabyte, its exact value was ambiguous until the IEC introduced 'gibibyte' (GiB) in 1998 for the binary definition. Storage manufacturers have consistently used the decimal definition for marketing purposes.
Current Use
Gigabytes are the standard unit for measuring storage capacity of smartphones, USB drives, and SSDs. They are also used for mobile data plans and describing application sizes. A typical smartphone has 64 to 512 GB of storage.
