Data storage units trace the evolution of computing. A byte settled on 8 bits by IBM in the 1960s. Kilobytes originally meant 1,024 bytes (binary). Hard-drive marketers later adopted the decimal 1,000 bytes, creating the binary prefixes kiB, MiB, GiB in 1998 to resolve confusion.
Data storage conversion prevents cloud-cost overruns and capacity planning failures. A 1 TB backup requires 1,000 GB of cloud storage — but billing might charge by binary TiB. Misreading transfer speeds (MB/s vs Mb/s) wastes hours troubleshooting.
IT administrators, video editors, photographers, cloud engineers, and mobile users managing storage.
MB vs Mb (megabytes vs megabits). An 8 Mb/s internet connection downloads 1 MB/s. Storage vendors use decimal GB; OS uses binary GiB — a 500 GB drive shows ~465 GiB.
| Unit | Symbol | Base Equivalent | Common Use |
|---|---|---|---|
| Bit | b | 0 or 1 | Computing base |
| Byte | B | 8 bits | Storage |
| Kilobyte | KB | 1,000 B | Files |
| Megabyte | MB | 1,000 KB | Photos, docs |
| Gigabyte | GB | 1,000 MB | Video, apps |
| Terabyte | TB | 1,000 GB | Hard drives |
| Common Value | Equals |
|---|---|
| 1 GB | 1,000 MB |
| 1 TB | 1,000 GB |
| 1 MB/s | 8 Mb/s |
| 1 GiB | 1.074 GB |
Both exist. Hard-drive makers use decimal: 1 MB = 1,000 KB. Operating systems use binary: 1 MiB = 1,024 KiB. The binary prefix (MiB) was standardised in 1998 to reduce confusion.
The manufacturer labels 500 decimal GB (500 × 10⁹ bytes). Windows displays binary GiB (500 × 10⁹ ÷ 1,024³ ≈ 465 GiB).
