As such, the use of binary prefixes is only a convention. Altering this convention to agree with SI Prefixes such as in <a rel="nofollow" class="external text" href="http://support.apple.com/kb/TS2419?viewlocale=en_US">Apple's 2009 "Snow Leopard" release</a> and <a rel="nofollow" class="external text" href="https://wiki.ubuntu.com/UnitsPolicy">Ubuntu</a> could have been done at any time; however, for some reason it just stuck this way for much of the computer industry.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup></li> <li>For many applications (primarily the storage capacity of <a href="/wiki/Hard_disk_drive" title="Hard disk drive">hard disk drives</a> and <a href="/wiki/Data_rate" title="Data rate">data rates</a> for telecommunications), the decimal convention is retained, whereby one kilobit is exactly one thousand bits and one megabyte is exactly one million bytes.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup></li> <li>There are many WP articles in which the same symbol (eg MB) is used with two different meanings, often jumping between them in the same paragraph or section, sometimes even in the same sentence.

The binary prefix yobi- means 1024<sup>8</sup> (≈1.21×10<sup>24</sup>), which differs by 21% from the conventional decimal interpretation of yotta-.</li> <li>In December 1998, in an attempt to resolve the ambiguity the <a href="/wiki/International_Electrotechnical_Commission" title="International Electrotechnical Commission">International Electrotechnical Commission</a> (IEC) introduced a new set of prefixes <a href="/wiki/Kibi-" class="mw-redirect" title="Kibi-">kibi-</a>, <a href="/wiki/Mebi-" class="mw-redirect" title="Mebi-">mebi-</a> and <a href="/wiki/Gibi-" class="mw-redirect" title="Gibi-">gibi-</a> for the binary meanings, with symbols Ki-, Mi- and Gi- so that 1 KiB (one <a href="/wiki/Kibibyte" class="mw-redirect" title="Kibibyte">kibibyte</a>) = 1024 B, 1 MiB (one <a href="/wiki/Mebibyte" class="mw-redirect" title="Mebibyte">mebibyte</a>) = 1024<sup>2</sup> B and 1 GiB (one <a href="/wiki/Gibibyte" class="mw-redirect" title="Gibibyte">gibibyte</a>) = 1024<sup>3</sup> B. In the IEC standard, the prefixes kilo-, mega- etc are reserved for their original decimal meanings.</li> <li>In March 2005, the IEC prefixes were adopted by the <a href="/wiki/Institute_of_Electrical_and_Electronics_Engineers" title="Institute of Electrical and Electronics Engineers">Institute of Electrical and Electronics Engineers</a> (IEEE) after a two-year trial period.</li> <li>The use of IEC prefixes has been approved by national and international standards bodies, including, in addition to IEC and IEEE, the <a href="/wiki/International_Bureau_of_Weights_and_Measures" title="International Bureau of Weights and Measures">International Bureau of Weights and Measures</a> (the standards body responsible for the <a href="/wiki/SI" class="mw-redirect" title="SI">SI</a> system of units), the <a href="/wiki/European_Committee_for_Electrotechnical_Standardization" title="European Committee for Electrotechnical Standardization">European Committee for Electrotechnical Standardization</a> (CENELEC) and the US <a href="/wiki/NIST" class="mw-redirect" title="NIST">National Institute of Standards and Technology</a>.</li> <li>The binary prefixes defined by the IEC are now incorporated in the <a href="/wiki/ISO/IEC_80000" title="ISO/IEC 80000">International System of Quantities</a> (ISQ).</li> <li>The alternative (binary use of SI-like prefixes) is deprecated by the same standards bodies.</li> <li>Use of IEC prefixes in popular literature is rare, making them unfamiliar to many readers.

Despite this ambiguity, there are many WP articles in which kilobyte, megabyte and/or gigabyte are used in this way. In this situation, the IEC prefixes provide an ideal disambiguation tool because they are unambiguous and succinct.</li> <li>Deprecation (of IEC prefixes) increases the difficulty threshold for disambiguation, reducing the rate at which articles can be disambiguated by expert editors.</li> <li>In turn this reduces the total number of articles that can be further improved by less expert editors with footnotes etc (assuming that there is consensus to do so).</li> <li>Deprecation is interpreted by some editors as a justification for changing unambiguous units into ambiguous ones.</li> <li>Removing IEC prefixes from articles, even when disambiguated with footnotes, destroys a part of the information that was there before, because it requires an expert to work out which footnote corresponds to which use in the article.</li> <li>In the long term, the use of IEC prefixes would ultimately avoid the need to use same symbol (e.g., MB) with two different meanings. This may sound like a <a href="/wiki/Opium_pipe" title="Opium pipe">pipe dream</a>, but it could be implemented as a user preference, so that readers could choose between familiar (ambiguous) units and (unfamiliar) unambiguous ones.</li> <li>The main argument for not using IEC prefixes is the unfamiliarity of, for example, the mebibyte (MiB) compared with the megabyte (MB). The unfamiliarity is not disputed, but is not relevant to disambiguation. The point is that disambiguation is rare and therefore all disambiguation methods are unfamiliar.</li> <li>Alternative disambiguation methods are either cumbersome (i.e., exact numbers of bytes), difficult and time-consuming to implement in a manner that is clear to the reader (i.e., footnotes)<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup> or unlikely to be understood (i.e. exponentiation).</li></ol> <dl><dd><b>In conclusion</b>, disambiguation is not easy, so it would be unwise to discard the simplest disambiguation tool at our disposal just because it is unfamiliar. The best disambiguation method has yet to be established, so it is premature to deprecate this one.</dd></dl> <div class="mw-heading mw-heading3"><h3 id="See_also">See also</h3></div> <ul><li><a href="/wiki/Binary_prefix" title="Binary prefix">Binary prefix</a></li> <li><a href="/wiki/Timeline_of_binary_prefixes" title="Timeline of binary prefixes">Timeline of binary prefixes</a></li> <li>User pages <ul><li>A <a href="/wiki/User:Omegatron/Binary_prefix_rationale" title="User:Omegatron/Binary prefix rationale">case for the use of IEC prefixes</a> on Wikipedia by <a href="/wiki/User:Omegatron" title="User:Omegatron">Omegatron</a> .</li> <li>A <a href="/wiki/User:Quilbert/IEC" title="User:Quilbert/IEC">discussion page</a> by <a href="/wiki/User:Quilbert" title="User:Quilbert">Quilbert</a>.</li></ul></li></ul> <div class="mw-heading mw-heading3"><h3 id="Footnotes">Footnotes</h3></div> <style data-mw-deduplicate="TemplateStyles:r1239543626">.mw-parser-output .reflist{margin-bottom:0.5em;list-style-type:decimal}@media screen{.mw-parser-output .reflist{font-size:90%}}.mw-parser-output .reflist .references{font-size:100%;margin-bottom:0;list-style-type:inherit}.mw-parser-output .reflist-columns-2{column-width:30em}.mw-parser-output .reflist-columns-3{column-width:25em}.mw-parser-output .reflist-columns{margin-top:0.3em}.mw-parser-output .reflist-columns ol{margin-top:0}.mw-parser-output .reflist-columns li{page-break-inside:avoid;break-inside:avoid-column}.mw-parser-output .reflist-upper-alpha{list-style-type:upper-alpha}.mw-parser-output .reflist-upper-roman{list-style-type:upper-roman}.mw-parser-output .reflist-lower-alpha{list-style-type:lower-alpha}.mw-parser-output .reflist-lower-greek{list-style-type:lower-greek}.mw-parser-output .reflist-lower-roman{list-style-type:lower-roman}</style><div class="reflist"> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-1"><span class="mw-cite-backlink"><b><a href="#cite_ref-1">^</a></b></span> <span class="reference-text"><a href="/wiki/Megabyte" title="Megabyte">MB</a> even has a third meaning, equal to 1000 KiB or 1,024,000 B</span> </li> <li id="cite_note-2"><span class="mw-cite-backlink"><b><a href="#cite_ref-2">^</a></b></span> <span class="reference-text"><a rel="nofollow" class="external text" href="http://reviews.cnet.com/8301-13727_7-10330509-263.html">Snow Leopard changes how file and drive sizes are calculated</a></span> </li> <li id="cite_note-3"><span class="mw-cite-backlink"><b><a href="#cite_ref-3">^</a></b></span> <span class="reference-text">According to the <a rel="nofollow" class="external text" href="http://www.idema.org/_smartsite/modules/local/data_file/show_file.php?cmd=download&data_file_id=1066">LBA Count for IDE Hard Disk Drives Standard</a> from the website of the International Disk Drive Equipment and Materials Association <a rel="nofollow" class="external text" href="http://www.idema.org/_smartsite/modules/local/data_file/show_file.php?cmd=standards&cat=103&h=1#">(IDEMA)</a>, there are 1,000,194,048 bytes (1,953,504 logical blocks x 512 bytes/logical block) per nominal gigabyte of hard drive storage.</span> </li> <li id="cite_note-4"><span class="mw-cite-backlink"><b><a href="#cite_ref-4">^</a></b></span> <span class="reference-text">This problem is illustrated by <a class="external text" href="https://en.wikipedia.org/w/index.php?title=Address_space_layout_randomization&oldid=229480138">Address space layout randomization</a>, which includes the confusing disambiguation footnote "Transistorized memory, such as RAM and cache sizes (other than solid state disk devices such as USB drives, CompactFlash cards, and so on) as well as CD-based storage size are specified using binary meanings for K (1024<sup>1</sup>), M (1024<sup>2</sup>), G (1024<sup>3</sup>), ..."</span> </li> </ol></div></div>    </div><noscript><img src="https://login.wikimedia.org/wiki/Special:CentralAutoLogin/start?type=1x1" alt="" width="1" height="1" style="border: none; position: absolute;"></noscript> <div class="printfooter" data-nosnippet="">Retrieved from "<a dir="ltr" href="https://en.wikipedia.org/w/index.php?title=User:Thunderbird2/The_case_against_deprecation_of_IEC_prefixes&oldid=1164193834">https://en.wikipedia.org/w/index.php?title=User:Thunderbird2/The_case_against_deprecation_of_IEC_prefixes&oldid=1164193834</a>"</div></div> <div id="catlinks" class="catlinks catlinks-allhidden" data-mw="interface"></div> </div> </main> </div> <div class="mw-footer-container"> <footer id="footer" class="mw-footer" > <ul id="footer-info"> <li id="footer-info-lastmod"> This page was last edited on 8 July 2023, at 08:23<span class="anonymous-show"> (UTC)</span>.</li> <li id="footer-info-copyright"><span class="nowraplinks">This version of the page has been <a href="/wiki/Help:Page_history" title="Help:Page history">revised</a>.
