SI Decimal vs Binary: Why MB to MiB 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 0.953674316406, which is why MB to MiB is not a round number.
| Unit | Standard | Prefix step | 1 unit equals |
|---|---|---|---|
| Megabyte (MB) | SI decimal | 1,000 | 8,000,000 bits |
| Mebibyte (MiB) | Binary (IEC) | 1,024 | 8,388,608 bits |
FAQs: Megabyte to Mebibyte Conversion
6 questions Quick answers on converting megabytes to mebibytes, using the same factors as the converter above.
-
How many mebibytes are in 1 megabyte?
1 MB = 0.953674316406 MiB
1 Megabyte (MB) equals 0.953674316406 Mebibytes using the SI decimal standard.
-
How many megabytes are in 1 mebibyte?
1 MiB = 1.048576 MB
1 Mebibyte (MiB) equals 1.048576 Megabytes.
-
How do I convert megabytes to mebibytes?
MB × 0.953674316406 = MiB
Multiply the megabyte value by 0.953674316406 to get mebibytes. For example, 10 MB = 9.5367431641 MiB. To convert back (vice versa), multiply mebibytes by 1.048576.
-
Is a megabyte bigger than a mebibyte?
MiB is 1.048576× larger than MB
No. 1 MB = 0.953674316406 MiB, so the mebibyte is larger — 1 MiB = 1.048576 MB.
-
Why is MB to MiB 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 MB = 0.953674316406 MiB instead of a round number.
-
What is Megabyte (MB) commonly used for?
Common uses of the megabyte (MB) include: MP3 files, high-resolution images, short video clips, software installers.
