Bytes to MB Data Size Converter
Convert data sizes between bytes, kilobytes, megabytes, gigabytes, terabytes, and petabytes. This tool uses binary (1024-based) conversion, which is the standard used by operating systems and memory specifications.
Data storage is measured in bytes, with each larger unit being 1024 times the previous one in binary notation. This converter uses the binary standard (powers of 1024) that operating systems report.
Binary conversion factors:
- 1 Kilobyte (KB) = 1,024 Bytes
- 1 Megabyte (MB) = 1,024 KB = 1,048,576 Bytes
- 1 Gigabyte (GB) = 1,024 MB = 1,073,741,824 Bytes
- 1 Terabyte (TB) = 1,024 GB = 1,099,511,627,776 Bytes
- 1 Petabyte (PB) = 1,024 TB
Quick Reference Table:
| Bytes | KB | MB | GB |
|---|---|---|---|
| 1,024 | 1 | 0.001 | 0.000001 |
| 1,048,576 | 1,024 | 1 | 0.001 |
| 1,073,741,824 | 1,048,576 | 1,024 | 1 |
| 1,099,511,627,776 | 1,073,741,824 | 1,048,576 | 1,024 |
Note: Storage manufacturers use decimal (1000-based) units (GB = 1,000,000,000 bytes), which is why a "1 TB" drive shows approximately 931 GB in your operating system. This converter uses binary units to match what your OS reports.
