Byte per Second (B/s)
Bytes per second measure how fast files move: one byte per second is eight bits per second.
Symbol: B/s
Quantity: data transfer rate (bandwidth)
SI relation: 1 B/s = 8 bps (exact)
Derivation: 1 B/s = 8 bit/s.
Exact: yes, by definition
Typical uses
- File transfer speeds
- Disk throughput at the byte level
Convert bytes per second to other units
| Conversion | 1 B/s equals | Reverse |
