How to convert mebibytes to megabytes
To convert mebibytes (MiB) to megabytes (MB), multiply the value in mebibytes by 1.048576.
MB = MiB × 1.048576 (decimal)
MB = MiB × 1 (binary)
Example: 5 MiB = 5.24288 MB, or 5 MB in binary.
Decimal (SI) counting steps by 1,000 and is what drive makers, macOS and phones use. Binary counting steps by 1,024 and is what Windows and RAM use; its unambiguous IEC names are KiB, MiB and GiB. Bits are decimal either way.
You can also type 5 MiB to MB into the smart calculator, or mix units: 1 MiB + 1 MB.

About the units
Mebibyte (MiB)
Exactly 1,048,576 bytes, or 1,024 KiB.
Megabyte (MB)
In decimal mode 1,000,000 bytes (1,000 KB); in binary mode 1,048,576 bytes (1,024 KB).
Digital storage is counted in bits and bytes (1 byte = 8 bits). There are two ways to count bytes. Decimal (SI) prefixes step by 1,000: 1 KB = 1,000 B and 1 GB = 1,000 MB, which is how drive makers, macOS, iOS and Android report sizes. Binary prefixes step by 1,024: 1 KB = 1,024 B and 1 GB = 1,024 MB, which is how Windows and RAM count (the IEC names for these are KiB, MiB and GiB). Bits are always decimal: 1 Kb = 1,000 b.
Questions and answers
How many megabytes are in a mebibyte?
One mebibyte (MiB) equals 1.048576 megabytes in decimal (SI) counting, or 1 megabytes in binary counting (1 KB = 1,024 B), which Windows uses.
How do I convert mebibytes to megabytes?
To convert mebibytes to megabytes, multiply the value in mebibytes by 1.048576. The formula is MB = MiB × 1.048576. For example, 5 MiB = 5.24288 MB.
What is 5 MiB in MB?
5 mebibytes is 5.24288 megabytes.
Which is bigger, a mebibyte or a megabyte?
A mebibyte is bigger: 1 MiB = 1.048576 MB.
Is 1 GB equal to 1,000 MB or 1,024 MB?
Both are in use. In decimal (SI) counting, which drive makers, macOS, iOS and Android use, 1 GB = 1,000 MB. In binary counting, which Windows and RAM use, 1 GB = 1,024 MB; the unambiguous IEC name for that size is the gibibyte (GiB). ConvertEasy has a Decimal / Binary switch so KB, MB, GB and TB follow whichever you need, while KiB, MiB and GiB are always binary.
Are kilobits 1,000 or 1,024 bits?
ConvertEasy treats bits as decimal in both modes: 1 Kb = 1,000 b, 1 Mb = 1,000 Kb. A byte is always 8 bits, so only byte units (KB, MB, GB…) change with the switch.
Does this MiB to MB converter work offline?
Yes. ConvertEasy is a progressive web app: after your first visit it keeps working with no connection, and you can install it to your home screen from the browser menu.
