Megabytes to gigabytes (MB to GB)
The answer, the exact formula and a table with the values people look up most.
1 MB = 0.001 GB1 GB = 1000 MBGigabytes = Megabytes ÷ 1000Example: 750 MB = 0.75 GB
1 MB = 0.001 GB
A kilobyte is 1000 bytes, but a kibibyte is 1024. That is why a 1 TB drive shows up as 931 GB: the manufacturer counts in thousands and the computer counts in 1024s. Neither is lying, they count differently.

The two units
Megabyte MB
A megabyte (MB) is 1,000,000 bytes in the decimal system storage makers use; some operating systems show binary mebibytes (MiB, 1,048,576 bytes) labeled as MB.
Gigabyte GB
A gigabyte (GB) is 1,000 megabytes, one billion bytes; that is why a 1 TB drive shows up as about 931 GB in Windows, which counts in binary units.
Frequently asked questions
How many gigabytes are 750 megabytes?
750 MB = 0.75 GB.
What is the formula to convert megabytes to gigabytes?
Gigabytes = Megabytes ÷ 1000. 750 MB = 0.75 GB.
Is this conversion exact?
It uses the decimal definition (1 GB = 1,000 MB) that storage makers and networks use. Windows and some apps count in binary (1 GiB = 1,024 MiB), which is why the numbers they show are about 7% lower.
