View the megabyte data unit pageHow to Convert Mebibytes to Megabytes
To convert mebibytes (binary/IEC) to megabytes (decimal/SI), multiply by 1.048576. Binary units use base 1,024, while decimal units use base 1,000—this creates small differences that accumulate at larger scales.
MiB is a binary (IEC) unit where 1 MiB = 1,024 of the smaller unit. Operating systems like Windows typically display storage using binary calculations.
MB is a decimal (SI) unit where 1 MB = 1,000 of the smaller unit. Storage manufacturers use decimal units, which is why a "1 TB" drive shows less in Windows. Related: Kilobits to Bits.
1 MiB = 1.048576 MB (using SI decimal standard) — which means there are 1.048576megabytes in every mebibyte.

SI Decimal vs Binary: Why MiB to MB Is Not a Round Number
Megabyte (MB) is an SI decimal unit: each prefix step multiplies by 1,000, so 1 MB = 8,000,000 bits. Mebibyte (MiB) is an IEC binary unit: each prefix step multiplies by 1,024, so 1 MiB = 8,388,608 bits. Dividing one by the other gives 1.048576, which is why MiB to MB is not a round number.
| Unit | Standard | Prefix step | 1 unit equals |
|---|---|---|---|
| Mebibyte (MiB) | Binary (IEC) | 1,024 | 8,388,608 bits |
| Megabyte (MB) | SI decimal | 1,000 | 8,000,000 bits |

6 questions Quick answers on converting mebibytes to megabytes, using the same factors as the converter above.
-
How many megabytes are in 1 mebibyte?
1 MiB = 1.048576 MB
1 Mebibyte (MiB) equals 1.048576 Megabytes using the SI decimal standard.
-
How many mebibytes are in 1 megabyte?
1 MB = 0.953674316406 MiB
1 Megabyte (MB) equals 0.953674316406 Mebibytes.
-
How do I convert mebibytes to megabytes?
MiB × 1.048576 = MB
Multiply the mebibyte value by 1.048576 to get megabytes. For example, 10 MiB = 10.48576 MB. To convert back (vice versa), multiply megabytes by 0.953674316406.
-
Is a mebibyte bigger than a megabyte?
MiB is 1.048576× larger than MB
Yes. 1 MiB = 1.048576 MB, so the mebibyte is the larger data storage unit.
-
Why is MiB to MB not a round number?
1 MB = 8,000,000 bits · 1 MiB = 8,388,608 bits
Megabyte (MB) is an SI decimal (base 10) unit and Mebibyte (MiB) is a binary IEC (base 2) unit, so their prefixes step by 1,000 and 1,024. That is why 1 MiB = 1.048576 MB instead of a round number.
-
What is Mebibyte (MiB) commonly used for?
Common uses of the mebibyte (MiB) include: Linux file sizes, RAM specifications, software download sizes.
