kibibyte

(unit)
The official ISOame for 1024 bytes, to distinguish it from 1000 bytes which they call a kilobyte. "Mebibyte", "Gibibyte", etc, are prefixes for other powers of 1024. Although this new naming standard has been widely reported in 2003, it seems unlikely to catch on.

NIST binary

In 1995, the National Institute of Standards & Technology defined a new standard for designating binary numbers in order to eliminate ambiguity. For example, one megabyte can mean 1,000,000 (106) bytes or 1,048,576 (220) bytes, which is the true binary value.

The traditional kilo, mega, etc. designations were changed to kibi, mebi, etc. The first two letters of the word were retained followed with "bi" for binary (see table below).

Will It Catch On?
After decades, NIST measurements are not mainstream but are used to avoid ambiguity. See binary values.
