| Unit | Decimal (SI) | Binary (IEC) | Difference |
|---|---|---|---|
| KB / KiB | 1,000 bytes | 1,024 bytes | 2.4% |
| MB / MiB | 1,000,000 | 1,048,576 | 4.9% |
| GB / GiB | 1,000,000,000 | 1,073,741,824 | 7.4% |

| PB / PiB | 1015 | 250 | 12.6% |
Manufacturers use 1 TB = 1012 bytes. Windows uses 1 TiB = 240 bytes. The 7-10% gap is a labeling difference, not missing space.
KB = 1,000 bytes (SI). KiB = 1,024 bytes (binary). Most systems blur the distinction.
1,000 MB (decimal) or 1,024 MiB (binary).
