Kilobyte per second to Kilobit per second

Exact answer: 1 kB/s = 8 kbit/s (exact defined factor)

Kilobyte per second and Kilobit per second describe the same quantity from the Data rate family but come from different systems of units. The factor is defined exactly. Data rate describes bandwidth, transmission speed and storage throughput.

Examples

011 kB/s = 8 kbit/s

Example value from the reference table. Internal calculation uses stored factors; display output is rounded.

02Common mistake

Mbit/s and MB/s differ by a factor of eight because one byte holds eight bits. Providers usually advertise Mbit/s while download tools display MB/s.

03Base unit: bit/s

1 kB/s = 8000 bit/s. Then the value is converted through the base unit bit/s into Kilobit per second.
