Unit family
データ
KB, MB and GB are decimal. KiB, MiB and GiB are binary. This distinction explains many apparent storage gaps.
| Unit | Symbol | 式 |
|---|---|---|
| Bit | bit | 8 bit = 1 Byte |
| Byte | B | base |
| Kilobyte | KB | 1 KB = 1000 B |
| Megabyte | MB | 1 MB = 1,000,000 B |
| Gigabyte | GB | 1 GB = 1,000,000,000 B |
| Terabyte | TB | 1 TB = 10¹² B |
| Kibibyte | KiB | 1 KiB = 1024 B |
| Mebibyte | MiB | 1 MiB = 1024 KiB |
| Gibibyte | GiB | 1 GiB = 1024 MiB |
| Tebibyte | TiB | 1 TiB = 1024 GiB |

Common questions
Which base unit does データ use?
UnitCloud normalises this family through Byte. That keeps tables, direct conversions and batch output consistent.
What is the most common mistake for データ?
KB, MB and GB are decimal. KiB, MiB and GiB are binary. This distinction explains many apparent storage gaps.
How does UnitCloud round?
UnitCloud keeps calculating with stored factors and rounds only the displayed output by selected precision.
