While the numerical difference between the decimal and binary interpretations is relatively small for the kilobyte (about 2% smaller than the kibibyte), the systems deviate increasingly as units grow larger (the relative deviation grows by 2.4% for each three orders of magnitude). For example, a power-of-10-based yottabyte is about 17% smaller than power-of-2-based yobibyte.

Percentage difference between decimal and binary interpretations of the unit prefixes grows with increasing storage size
addressable unit of data storage large enough to hold any member of the basic character set of the execution environment
