How to Calculate Data Storage
What is Data Storage?
Digital storage is measured in binary units based on powers of 2. A byte contains 8 bits. Storage sizes scale through kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), and petabytes (PB). Note: drive manufacturers use SI (decimal) prefixes while operating systems use binary prefixes — a 500GB drive shows as ~465GB in Windows.
Step-by-Step Guide
- 11 byte = 8 bits
- 21 KB (kibibyte) = 1,024 bytes (binary) or 1,000 bytes (SI)
- 31 MB = 1,024 KB = 1,048,576 bytes (binary)
- 41 GB = 1,024 MB ≈ 1 billion bytes (SI)
- 5Hard drive manufacturers use SI; operating systems use binary — causing the apparent discrepancy
