Definition and symbol
The byte per second is written with the symbol B/s. In professional writing, keep the number and symbol together, preserve capitalization, and avoid replacing the symbol with a similar-looking informal abbreviation unless the source uses it.
Scale and relationships
Byte per Second is best understood relative to nearby data transfer rate units. Data transfer rate measures information moved per unit time. Network plans usually use bits per second, while file-transfer tools often display bytes per second. The table below shows the exact Xunits relationship used by converter pages.
| Unit | Symbol | Relationship |
|---|---|---|
| Bit per Second | bps | 1 bps is the base reference for this Xunits data transfer rate category. |
| Kilobit per Second | Kbps | 1 Kbps = 1,000 bps |
| Megabit per Second | Mbps | 1 Mbps = 1,000,000 bps |
| Gigabit per Second | Gbps | 1 Gbps = 1e+9 bps |
| Byte per Second | B/s | 1 B/s = 8 bps |
| Kilobyte per Second | KB/s | 1 KB/s = 8,000 bps |
| Megabyte per Second | MB/s | 1 MB/s = 8,000,000 bps |
| Gigabyte per Second | GB/s | 1 GB/s = 8e+9 bps |
Where byte per second is used
Data transfer rate units appear in internet plans, Wi-Fi testing, downloads, uploads, backups, streaming, server bandwidth, and network troubleshooting. Byte per Second is especially useful when the source instrument, document, product listing, or regional convention uses B/s as its native unit.
Common mistakes
- Do not ignore capitalization. Mbps means megabits per second, while MB/s means megabytes per second, and one byte equals eight bits.
- Do not compare B/s values with another unit until both values are converted to the same basis.
- Do not round too early when the value is used for sizing, limits, billing, reporting, or technical documentation.
