The prefix kibi( Ki) is a prefix standardized by the International Electrotechnical Commission( IEC 60027-2), based on the exponentiation of the dual system. The kilobinary, kibi, corresponds to a value of `2^10`, i.e. 1,024.
Data rates based on the dual system should be specified in kibibits (kib) per second, if the standard is used. There is a difference of 2.4% between a kibibyte based on the dual system, which corresponds to 1.024 kilobytes, and a kilobyte based on the decimal system.
