... a bunch of fucked up shit is what's been used globally. The current SI / IEC standards have been outlined in the table, with accordant application notes found elsewhere, and are slowly making their way through industry. Trying to interpose the systems, prefixes and quantities creates confusion under the standards, especially when not converted using correct math. File / memory sizes are in binary IEC bytes if 2's context. Data transmission rates are in decimal SI bits. JEDEC (and its "K") is an old single sector private nonstandard... """" The JEDEC specification ... refers to the IEEE/ASTM SI 10-1997 standard as stating, that "this practice frequently leads to confusion and is deprecated" ... The document further refers to the description of the IEC binary prefixes in Amendment 2 of IEC 60027-2, "Letter symbols to be used in electrical technology", for an alternate system of prefixes and includes a table of the IEC prefixes in the note. The document notes that these prefixes are used in their decimal sense for serial communication data rates measured in bits. """" IEC 60027-2 Amendment 2, as published in January 1999, was the first international standard defining the binary prefixes, as proposed by International Electrotechnical Commission (IEC) since 1996 (kibi- (Ki), mebi- (Mi), gibi- (Gi) and tebi- (Ti)) but extended them up to pebi (Pi) and exbi- (Ei). This didn't change in the second edition of the standard, published in 2000, but the third edition in 2005 finally added prefixes zebi- (Zi) and yobi- (Yi). The harmonized ISO/IEC IEC 80000-13:2008 standard supersedes subclauses 3.8 and 3.9 of IEC 60027-2:2005.
