This category of measurement units is defined by the "computer data rate" type, which is an non-SI quantity.
The non-SI unit for computer data rate is the bit/second.
In telecommunications and computer network speed measurement, bit rate or data transfer rate is the average number of bits, characters, or blocks per unit time passing between equipment in a data transmission system. Unlike many other computer-related units, 1 kbps is traditionally defined as 1000 bps, not 1024 bps.
