What is 1 mebibyte in bytes?
1 mebibyte is equal to exactly 1,048,576 bytes.
1 × 1,048,576 = 1,048,576 bytes
1 mebibyte = 1,048,576 bytes
Mebibytes to Bytes formula
B = MiB × 1,048,576
The mebibytes to bytes conversion factor is 1,048,576, which is exact by definition. 1 mebibyte = 1,048,576 bytes, and 1 byte = 0.000000953674 mebibytes.
Regional note. Decimal (SI) units count in powers of 1,000 while binary (IEC) units count in powers of 1,024. This is why a drive sold as 1 TB is reported by most operating systems as about 931 GiB.
Worked examples
- 2 mebibytes = 2,097,152 bytes — 2 × 1,048,576 = 2,097,152 bytes
- 32 mebibytes = 33,554,432 bytes — 32 × 1,048,576 = 33,554,432 bytes
- 256 mebibytes = 268,435,456 bytes — 256 × 1,048,576 = 268,435,456 bytes

When you need to convert mebibytes to bytes
- Checking whether a file fits inside a storage or upload limit.
- Working out how much of a mobile data allowance a download will use.
- Reconciling the capacity printed on a drive with the smaller figure the operating system reports.
Common mistakes to avoid
- Dividing when you should multiply. Because 1 mebibyte = 1,048,576 bytes, the answer should be larger than the number you started with.
- Treating 1 kB as 1,024 bytes. Storage and network figures use decimal units of 1,000; operating systems usually report binary units of 1,024, which is why a 1 TB drive shows as about 931 GiB.
- Rounding too early. Convert first at full precision, then round the final answer to the precision the task actually needs.
How precise does the answer need to be?
Round to two decimals for human-readable sizes. When you are checking a hard limit, use the exact figure: a file 0.4% over an upload cap still fails.
How these units are defined
- Mebibyte (MiB): 1,024 kibibytes (1,048,576 bytes). This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
- Byte (B): Eight bits. This unit's relationship to the SI base unit is exact by definition, so no rounding enters the conversion factor.
