Mebibyte facts for kids
A mebibyte is a unit of measure used for digital information. It is a way to count how much data a computer can store or process. The word mebibyte is a shorter way of saying "mega binary byte." Its symbol is MiB.
One mebibyte is exactly 1,048,576 bytes. This number comes from multiplying 1024 by 1024. Think of a byte as a tiny piece of digital information.

What is a Mebibyte?
A mebibyte is a unit of information or computer storage. It helps us measure the size of files, programs, or how much space is on a hard drive.
This unit is part of a system that uses powers of two (binary numbers). This is because computers work with binary code (0s and 1s).
Mebibyte vs. Megabyte
You might have heard of a megabyte (MB) before. The mebibyte (MiB) and megabyte (MB) are very similar, but they are not exactly the same. This difference can sometimes cause confusion.
Understanding the Difference
- A mebibyte (MiB) is based on powers of two. It equals 1,048,576 bytes. This is often called a "binary megabyte."
- A megabyte (MB) is usually based on powers of ten. It equals 1,000,000 bytes. This is often called a "decimal megabyte."
Even though the numbers are close, using the wrong one can lead to small differences in how storage is reported. For example, a hard drive advertised as 1000 MB (1 billion bytes) might show up as 953 MiB on your computer. This is because your computer uses mebibytes to measure the space.
Why was the Mebibyte created?
The mebibyte unit was created to clear up confusion between the two different meanings of "megabyte."
Standardization by Experts
The MiB unit was officially defined by the International Electrotechnical Commission (IEC) in December 1998. Important groups like the IEEE and the CIPM also support using mebibytes and similar units. This helps everyone use the same clear measurements for computer data.
Larger and Smaller Units
The mebibyte is part of a family of binary units.
These units help us measure very large amounts of data, like the size of video games or movies.
