The International Electrotechnical Commission has attempted to define (2) as the kilobyte and call (1) an kibibyte -- a term which however has not caught on.
See integral data type.

A gigabyte is 1024 times an megabyte.



To clarify the meaning(1) above, the International Electrotechnical Commission (IEC), a standards body, in 1997 proposed short unions of the International System of Units (SI) prefixes with the word "binary." Thus meaning (1) would be called a mebibyte.
This naming convention has not been widely accepted.
