How to convert mebibytes to gibibytes
To convert a measurement in mebibytes to gibibytes, multiply the value by 0.0009765625. The conversion factor comes from the relationship between both units and the byte.
For example, to convert 5 MiB to gibibytes: 5 × 0.0009765625 = 0.0048828125 GiB.
What is a mebibyte?
A mebibyte is exactly 1,048,576 bytes (2^20), the binary counterpart of the megabyte defined by the IEC. Part of the 1998 IEC binary-prefix standard, the mebibyte gives an unambiguous name to the 1,024-kibibyte value that was often loosely called a megabyte in software and operating systems.
Common uses of mebibytes include: RAM module and memory-region sizing; OS and utility file-size displays; Software buffer and cache allocation; Exact power-of-two data measurement.
What is a gibibyte?
A gibibyte is exactly 1,073,741,824 bytes (2^30), the binary counterpart of the gigabyte defined by the IEC. This is why a 1 GB figure and a 1 GiB figure differ by about 7%. The gibibyte resolves the most visible storage confusion: drive makers sell in decimal gigabytes while operating systems report in binary gibibytes, so a '500 GB' drive is about 465 GiB of usable, OS-reported space.
Common uses of gibibytes include: Operating-system storage and RAM reporting; Virtual-machine and disk-image sizing; Reconciling advertised vs. reported drive capacity; Exact power-of-two capacity in software.

Frequently asked questions
How many gibibytes are in one mebibyte?
One mebibyte (MiB) equals 0.0009765625 gibibytes (GiB). Multiply any value in mebibytes by 0.0009765625 to convert to gibibytes.
How do I convert mebibytes to gibibytes?
Multiply the value in mebibytes by 0.0009765625. For example, 5 MiB × 0.0009765625 = 0.0048828125 GiB.
How do I convert gibibytes to mebibytes?
Multiply the value in gibibytes by 1,024, or divide by 0.0009765625. Use the swap button on the converter above to reverse the direction.
Is the mebibyte to gibibyte conversion exact?
Decimal units (KB, MB, GB) use powers of 1000 per SI; binary units (KiB, MiB, GiB) use powers of 1024 per IEC. Both are exact — just be sure you are using the right family, since storage is often sold in decimal but reported by operating systems in binary.
What is the formula for mebibytes to gibibytes?
The formula is: GiB = MiB × 0.0009765625. This comes from the definition of both units relative to the byte.
