How to convert mebibytes to kilobytes
To convert a measurement in mebibytes to kilobytes, multiply the value by 1,048.576. The conversion factor comes from the relationship between both units and the byte.
For example, to convert 5 MiB to kilobytes: 5 × 1,048.576 = 5,242.88 KB.
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 kilobyte?
A kilobyte is 1,000 bytes under the SI decimal convention. Note that some contexts historically used 1,024 bytes; the 1,024-byte unit is properly the kibibyte (KiB). The 'kilo' prefix means 1,000 in SI, but early computing loosely used kilobyte for 1,024 bytes because it is close to 2^10. This ambiguity led the IEC to introduce the binary 'kibibyte' in 1998 to keep the two meanings distinct.
Common uses of kilobytes include: Small text documents and configuration files; Email message sizes; Web page and icon asset sizes; Marketing of storage where decimal units are used.

Frequently asked questions
How many kilobytes are in one mebibyte?
One mebibyte (MiB) equals 1,048.576 kilobytes (KB). Multiply any value in mebibytes by 1,048.576 to convert to kilobytes.
How do I convert mebibytes to kilobytes?
Multiply the value in mebibytes by 1,048.576. For example, 5 MiB × 1,048.576 = 5,242.88 KB.
How do I convert kilobytes to mebibytes?
Multiply the value in kilobytes by 0.000953674316, or divide by 1,048.576. Use the swap button on the converter above to reverse the direction.
Is the mebibyte to kilobyte 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 kilobytes?
The formula is: KB = MiB × 1,048.576. This comes from the definition of both units relative to the byte.
