@people reverting the edits to this: The list in its unedited state effectively doesn't contain the most widely used 1KB=1024B notation. The IEC poppycock is so rarely used that even including them in a table like this is just trying to push them down people's throats. If you really think it's necessary to even include those ridiculous -ibi units in this table, don't make them the primary/only notation in the table. Boatmurdered (talk) 00:57, 6 February 2012 (UTC)

They're not primary/only, and we include them for completeness and lack of ambiguity. --Cybercobra (talk) 01:20, 6 February 2012 (UTC)
The table has been reverted to a state where the binary value column is duplicated, and there is no way to quickly know that the binary values are slightly larger than the decimal values. In both cases, I am having trouble seeing this as anything but a step in the wrong direction.  :-( —Quantling (talk | contribs) 15:26, 6 February 2012 (UTC)
There is duplication because and only insofar as the SI prefixed units are ambiguous as to their meaning (decimal or binary?; c.f. User:Boatmurdered above and Kilobyte). As for losing the decimal approximations of the binary values, it makes the navbox rather wide and arguably would be better suited as actual article content (see Binary_prefix#Deviation_between_powers_of_1024_and_powers_of_1000). --Cybercobra (talk) 19:27, 6 February 2012 (UTC)

IEC, ISO and JEDEC Prefixes[edit]

The IEC and ISO prefixes are documented in international standards for magnitudes up to and including YB and YiB. They are also used in hundreds of scientific articles every year. The JEDEC prefixes are documented in a JEDEC standard up to and including GB. Like compvis I do not believe the JEDEC prefixes are used for large magnitudes. The version proposed by compvis is better than that proposed by arthur rubin. Dondervogel 2 (talk) 12:27, 14 April 2013 (UTC)

Merriam-Webster defines terabyte as "1024 gigabytes or 1,099,511,627,776 bytes" first and "one trillion bytes" second. My personal belief is that being concerned with using every available byte is infeasible beyond the megabyte level, so the distinction between the powers-of-ten based meanings and powers-of-two based meanings becomes less important for quantities of one gigabyte and above. Hence usage examples tend to be more approximate and it will often be hard to discern which meaning the author of an example had in mind.
The dictionary I cited does not have definitions for petabyte or exabyte. Jc3s5h (talk) 13:51, 14 April 2013 (UTC)
The argument repeatedly used against IEC prefixes is that they are not used, so let's look at usage. WP's exabyte cites one IBM article that goes up to 16 EB with binary meaning. That's only one article but it seems an important one. There seems no justification to claim though, as this template does, that JEDEC prefixes are applied to quantities larger than 1 EB.

See also: WP:COMPUNITS[edit]

The template currently includes WP:COMPUNITS under "See also". I removed it on the grounds that "generally article space should not link to WP space", but Jc3s5h restored it, saying that "template space is not article space, and the link to the WP space page is not visible in the transclusion of this template".

While I agree that WP:Template namespace is not Wikipedia:Article namespace, and that the "see also" list is not visible (being tagged as <noinclude>), I still do not believe it is appropriate. Wikipedia:SELF#In the Template and Category namespaces says (with my emphasis)

Limited use of self-references are sometimes found in the Template namespace and the Category namespace, such as with disambiguation and stub notices. Expanding this to other areas is not encouraged...

If we really think that a reference to the WP page is necessary at all, it should probably be a {{selfref}} hatnote, but even then I don't think it appropriate or necessary. Mitch Ames (talk) 05:04, 23 November 2013 (UTC)

I consider the general practice in English in this area to be unstable. We have popular usage avoiding the IEC prefix, but standards-making bodies endorsing them and discouraging the binary meaning of SI prefixes. Thus, I anticipate that some sort of readjustment is likely in the future. Links between WP guidelines and templates will make it easier to be aware of the areas that should be examined if the practice in the English language changes.
Also, reading Wikipedia:Manual of Style/Self-references to avoid, I think it only applies to material that is visible in articles. If you look at {{cite book}}, for example, the documentation is chock full of links to pages in template and WP space. Jc3s5h (talk) 15:35, 23 November 2013 (UTC)

The International System of Quantities (ISQ)[edit]

The so-called "IEC prefixes" are now part of the International System of Quantities (ISQ). Given that the ISQ is a broad collaboration between ISO and IEC, the heading "IEC" seems too narrow to describe the present situation. With this in mind I propose replacing the header "IEC" with "ISQ". Dondervogel 2 (talk) 11:29, 5 March 2014 (UTC)

Hm. As someone who generally prefers precise and current terminology, I concur. As someone who supports the notion of using the most familiar terms (e.g. WP:COMMONNAME), I have my doubts. Jeh (talk) 21:44, 5 March 2014 (UTC)
Fair comment. On the other hand, given that few readers have heard of IEC prefixes at all, even fewer will worry too much whether they are called "IEC prefixes" or "ISQ prefixes", so perhaps this is one of those times to favour precision. Dondervogel 2 (talk) 21:59, 5 March 2014 (UTC)
