Techopedia Explains Kibibyte

Kibibyte is related to kilobyte, which is equal to 103, or 1,000, bytes. It comes before mebibibyte and was created by the International Electrotechnical Commission (IEC) to replace the prefix "kilo," which stands for 1,024, in a computer science context. This of course conflicts with the standard metric definition of kilo, which is 1,000 units. Despite this, the use of the kibibyte never really caught on in the industry.
