Bytes (B) to Megabytes (MB) Converter
Type your storage value in the input field to find Megabytes (MB) equivalent of your Byte (B) value. 1 B = 0.000001 MB, calculated across both decimal (SI) and binary (IEC) standards.

How to Convert Bytes to Megabytes
To convert bytes to megabytes, divide by 1,000,000. This gives you the equivalent storage size in the target unit. Use our calculate MB to B.
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). Related: B to Kb conversion rate.
MB: A megabyte is 1,000 kilobytes or 1,000,000 bytes using the SI decimal standard. You might also need: converting Gibibytes to Megabytes.
1 B = 0.000001 MB (using SI decimal standard) — or equivalently, 1 MB = 1,000,000B.
B to MB Conversion Formula
// Convert B to MB
MB = B × 0.000001
// Reverse: Convert MB to B
B = MB × 1,000,000
Byte to Megabyte Conversion Examples
100 B = 0.0001 MB
256 B = 0.000256 MB
500 B = 0.0005 MB
1,000 B = 0.001 MB
2,048 B = 0.002048 MB
What Is a Byte?
A byte consists of 8 bits and is the standard unit for measuring digital storage. One byte can represent 256 different values (0-255). Learn more: Tebibytes in Zettabits.
The byte is a fundamental unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Use our Ybps to PB/s.
Common uses: File sizes, memory addressing, character encoding (ASCII, UTF-8) Try the B to Pb converter.
1 B = 8 bits = 1 bytes.
The byte can be abbreviated as B; for example, 1 byte can be written as 1 B.
What Is a Megabyte?
A megabyte is 1,000 kilobytes or 1,000,000 bytes using the SI decimal standard. Try the Tb to MB calculator.
The megabyte is a SI decimal unit of digital information storage. It uses base 1,000 following the SI (International System of Units) standard. Use our convert Gb to Yib.
Common uses: MP3 files, high-resolution images, short video clips, software installers Try the bps → KB/s.
1 MB = 8 × 10⁶ bits = 1 × 10⁶ bytes.
The megabyte can be abbreviated as MB; for example, 1 megabyte can be written as 1 MB.

SI Decimal vs Binary: Why Two Different Standards?
When converting bytes to megabytes, 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.
