How to convert kibibytes to mebibytes
To convert a measurement in kibibytes to mebibytes, multiply the value by 0.0009765625. The conversion factor comes from the relationship between both units and the byte.
For example, to convert 5 KiB to mebibytes: 5 × 0.0009765625 = 0.0048828125 MiB.
What is a kibibyte?
A kibibyte is exactly 1,024 bytes (2^10), the binary counterpart of the kilobyte defined by the IEC. Use it when you mean the power-of-two value. The IEC introduced the binary prefixes (kibi, mebi, gibi, ...) in 1998 to end the long-standing confusion between the decimal kilobyte (1,000 B) and the binary 1,024-byte unit that computing had informally called a kilobyte.
Common uses of kibibytes include: Memory and buffer sizes in software; Operating-system file-size reporting; Low-level programming and disk blocks; Any context needing an exact power-of-two size.
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.

Frequently asked questions
How many mebibytes are in one kibibyte?
One kibibyte (KiB) equals 0.0009765625 mebibytes (MiB). Multiply any value in kibibytes by 0.0009765625 to convert to mebibytes.
How do I convert kibibytes to mebibytes?
Multiply the value in kibibytes by 0.0009765625. For example, 5 KiB × 0.0009765625 = 0.0048828125 MiB.
How do I convert mebibytes to kibibytes?
Multiply the value in mebibytes by 1,024, or divide by 0.0009765625. Use the swap button on the converter above to reverse the direction.
Is the kibibyte to mebibyte 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 kibibytes to mebibytes?
The formula is: MiB = KiB × 0.0009765625. This comes from the definition of both units relative to the byte.
