About this tool
The megabyte (MB) and gigabyte (GB) are units of digital storage capacity, used to measure file sizes, RAM, and storage drives.
This converter follows the binary convention used by Windows and many other tools, where 1 gigabyte equals 1,024 megabytes (2¹⁰), rather than the decimal convention (1,000 MB) used by storage manufacturers and, since 2009, by macOS.
That difference in convention is exactly why a drive advertised as “1 TB” often shows up as roughly 931 GB in your operating system — both figures are correct, they're just counting in different bases.
