Decimal vs Binary
- Decimal (SI): 1 KB = 1,000 B — used by storage manufacturers
- Binary (IEC): 1 KiB = 1,024 B — used by operating systems
- A 1 TB drive shows as ~931 GiB in your OS
Frequently Asked Questions
What is the difference between MB and MiB?
MB (megabyte) uses the decimal system: 1 MB = 1,000,000 bytes (10^6). MiB (mebibyte) uses the binary system: 1 MiB = 1,048,576 bytes (2^20). The difference grows with size: 1 TB = 1,000 GB (decimal) vs 1 TiB = 1,024 GiB (binary). Operating systems often mix conventions, causing confusion.
Why does my hard drive show less space than advertised?
Manufacturers use decimal units (1 TB = 1,000,000,000,000 bytes), while operating systems display in binary units (1 TiB = 1,099,511,627,776 bytes). A '1 TB' drive appears as about 931 GiB in your OS. This is not missing space; it is a unit conversion difference.
How much data storage does 1 TB actually hold?
1 TB can store approximately 250,000 photos (4 MB each), 500 hours of HD video, 6.5 million document pages, or about 200,000 songs. Cloud services typically offer 2–15 GB free, with 1–2 TB plans for personal use. Most users need 256 GB to 1 TB of local storage.
