How to Convert Megabytes to Mebibytes
To convert megabytes (decimal/SI) to mebibytes (binary/IEC), multiply by 0.953674316406. Decimal units use base 1,000, while binary units use base 1,024. Check out our Mebibytes to MB calculator.
MB is a decimal (SI) unit—what storage manufacturers advertise. 1 MB = 1,000 of the smaller unit. You might also need: MB to Zebibytes converter.
MiB is a binary (IEC) unit—what operating systems often display. 1 MiB = 1,024 of the smaller unit. Try the Kilobytes to Mebibytes conversion.
1 MB = 0.953674316406 MiB (using SI decimal standard) — or equivalently, 1 MiB = 1.048576MB.
MB to MiB Conversion Formula
// Convert MB to MiB
MiB = MB × 0.953674316406
// Reverse: Convert MiB to MB
MB = MiB × 1.048576Megabyte to Mebibyte Conversion Examples

SI Decimal vs Binary: Why Two Different Standards?
When converting megabytes to mebibytes, different tools may give slightly different results. This is because there are two competing standards for measuring digital storage:
| Standard | Base | 1 KB equals | Used By |
|---|---|---|---|
| SI Decimal | 1000 | 1,000 bytes | Hard drive manufacturers, macOS, network speeds |
| Binary (IEC) | 1024 | 1,024 bytes | Windows, Linux (partially), RAM specifications |
Note: Our calculator defaults to SI decimal (base 1000) to match the box label. To match Windows, toggle the standard at the top of the calculator.
