To convert megabytes to bytes, multiply by 1,000,000. This gives you the equivalent storage size in the target unit.
MB: A megabyte is 1,000 kilobytes or 1,000,000 bytes using the SI decimal standard.
B: A byte consists of 8 bits and is the standard unit for measuring digital storage. One byte can represent 256 different values (0-255).
1 MB = 1,000,000 B (using SI decimal standard) — which means there are 1,000,000bytes in every megabyte.

SI Decimal vs Binary: Why Two Different Standards?
When converting megabytes to bytes, 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 above the converter.
FAQs: Megabyte to Byte Conversion
How many bytes are in 1 megabyte?
1 Megabyte (MB) equals 1,000,000 Bytes using the SI decimal standard.
How do I convert megabytes to bytes?
Multiply the megabyte value by 1,000,000 to get bytes. For example, 10 MB = 10,000,000 B.
Is a megabyte bigger than a byte?
Yes. 1 MB = 1,000,000 B, so the megabyte is the larger data storage unit.
What is Megabyte (MB) commonly used for?
MP3 files, high-resolution images, short video clips, software installers.
