Unit family
Dati
KB, MB and GB are decimal. KiB, MiB and GiB are binary. This distinction explains many apparent storage gaps.
| Unit | Symbol | Formula |
|---|---|---|
| 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 |

Factors come from the stored source family and are not derived from rounded display values.
UnitCloud keeps calculating with stored factors and rounds only the displayed output by selected precision.
Do not use as the sole basis for official, medical, safety-critical or contractual decisions.

Common questions
Which base unit does Dati use?
UnitCloud normalises this family through Byte. That keeps tables, direct conversions and batch output consistent.
What is the most common mistake for Dati?
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.
