Convert between megabytes (MB) and bytes (B) for measuring digital storage, file sizes, and data transfer in computing and technology applications.
Conversion Factor (Binary, Used in Computing):
1 Megabyte (MB) = 1,048,576 Bytes (B) = 1024² Bytes
B = MB × 1,048,576 | MB = B ÷ 1,048,576
*Note: Some industries use decimal (1 MB = 1,000,000 B) - toggle below for this standard
Accepts decimal values (e.g., 2 MB = 2,097,152 B)

Fundamental units of digital information storage used in computing and technology
Common digital files and their approximate sizes in both units:
| File Type | Bytes (B) | Megabytes (MB) |
|---|---|---|
| Plain text document (1 page) | ~2,000 B | ~0.0019 MB |
| High-resolution photo (JPEG) | ~3-5 MB = ~3-5 million B | 3-5 MB |
| MP3 song (3 minutes) | ~3-5 million B | 3-5 MB |
| PDF document (50 pages with images) | ~10-20 million B | 10-20 MB |
| Short video clip (1 minute) | ~50-100 million B | 50-100 MB |
| Mobile application | ~50-2000 million B | 50-2000 MB |
Common storage conversions for digital files, memory, and data transfer
Conversion Standard:
| Megabytes (MB) | = | Bytes (B) | Typical Storage Context |
|---|---|---|---|
| 0.001 MB | = | 1,024 B | Small text file |
| 0.1 MB | = | 104,858 B | Email with small attachment |
| 0.5 MB | = | 524,288 B | High-quality image thumbnail |
| 1 MB | = | 1,048,576 B | Several photos (low resolution) |
| 5 MB | = | 5,242,880 B | One high-quality photo |
| 10 MB | = | 10,485,760 B | Short MP3 audio file |
| 100 MB | = | 104,857,600 B | Small video clip or document collection |
Binary conversion uses 1024-based prefixes (1 MB = 1024² B). Decimal uses 1000-based prefixes (1 MB = 1000² B).
Common questions about megabytes, bytes, and digital storage conversions
The dual definitions stem from different historical contexts:
Binary (1024-based): 1 MB = 1024 × 1024 = 1,048,576 Bytes
Used in computing and software for memory and storage measurements
Decimal (1000-based): 1 MB = 1000 × 1000 = 1,000,000 Bytes
Used in marketing, hard drive manufacturing, and consumer electronics
This difference explains why a "100 GB" hard drive shows less capacity in your computer - the manufacturer uses decimal, while your OS uses binary measurement.
Use binary conversion (1024-based) for:
Use decimal conversion (1000-based) for:
These are related but distinct units in digital storage:
1 bit = Single binary digit (0 or 1) - the smallest unit of data
1 byte = 8 bits - the basic unit for storing a single character
1 kilobyte (KB) = 1024 bytes = 8192 bits
1 megabyte (MB) = 1024² bytes = 8,388,608 bits
Bits are typically used for measuring data transfer rates (e.g., internet speed in Mbps - megabits per second), while bytes are used for measuring storage capacity (e.g., file sizes in MB).
The binary prefix system extends to larger units as follows:
| Unit | Abbreviation | Equivalent in Bytes |
|---|---|---|
| Byte | B | 1 B |
| Kilobyte | KB | 1,024 B |
| Megabyte | MB | 1,048,576 B (1024²) |
| Gigabyte | GB | 1,073,741,824 B (1024³) |
| Terabyte | TB | 1,099,511,627,776 B (1024⁴) |
Each unit is 1024 times larger than the previous one in the binary system, or 1000 times larger in the decimal system.
The common discrepancy between advertised and displayed storage sizes happens because:
This converter helps reconcile these differences by allowing you to toggle between binary and decimal conversion standards.
