About Kilobyte per Second and Kilobit per Second

The kilobyte per second (KB/s) equals 8,000 bits per second (8 Kbps). It appears in file manager copy speed readouts and FTP transfer statistics. The kilobit per second (Kbps) equals 1,000 bits per second (SI decimal prefix). It is the standard unit for slow internet connections, audio streaming, and legacy modem speeds. One Kilobyte per Second equals 8 Kilobit per Second (1 KB-s = 8 Kbps). Kilobyte per Second to Kilobit per Second conversion comes up most often in file manager copy and move operations and in FTP and SFTP transfer speed readouts, typically when figures need restating for dial-up and early DSL connections (56 Kbps – 1 Mbps).

Precision and Rounding: Data transfer rates are almost always quoted in SI decimal prefixes (1 Kbps = 1,000 bps), not binary (1 Kibps = 1,024 bps). Internet service providers universally use SI prefixes. When converting to bytes per second, remember 1 byte = 8 bits exactly — never round this factor.

Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).

Worked Example

15 Kilobyte per Second equals 120 Kilobit per Second.

15 KB-s × 8 = 120 Kbps
