How to convert mebibytes to gigabytes
To convert a measurement in mebibytes to gigabytes, multiply the value by 0.001048576. The conversion factor comes from the relationship between both units and the byte.
For example, to convert 5 MiB to gigabytes: 5 × 0.001048576 = 0.00524288 GB.
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 gigabyte?
A gigabyte is 1,000,000,000 bytes (1,000 megabytes) under the SI decimal convention. The binary equivalent of 1,073,741,824 bytes is the gibibyte (GiB). The gigabyte became the standard consumer storage unit with the rise of hard drives, USB sticks, and smartphones. Drive makers market capacity in decimal gigabytes, while operating systems often report in binary gibibytes, which is why a '500 GB' drive shows as about 465 GB.
Common uses of gigabytes include: Hard drive, SSD, and USB flash storage capacity; Smartphone and tablet storage tiers; HD video and large software installs; RAM and memory-card sizing.

Frequently asked questions
How many gigabytes are in one mebibyte?
One mebibyte (MiB) equals 0.001048576 gigabytes (GB). Multiply any value in mebibytes by 0.001048576 to convert to gigabytes.
How do I convert mebibytes to gigabytes?
Multiply the value in mebibytes by 0.001048576. For example, 5 MiB × 0.001048576 = 0.00524288 GB.
How do I convert gigabytes to mebibytes?
Multiply the value in gigabytes by 953.674316, or divide by 0.001048576. Use the swap button on the converter above to reverse the direction.
Is the mebibyte to gigabyte 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 gigabytes?
The formula is: GB = MiB × 0.001048576. This comes from the definition of both units relative to the byte.
