Thus 1 mebibyte of RAM is 10242 bytes of RAM, one gibibyte or 1 GiB of RAM is 10243 bytes, and so on. {{cite web |title=IUCr annual report for 1995 |publisher=[[International Union of Crystallography]] |author=IUCr IUPAC Interdivisional Committee on Nomenclature and Symbols (IDCNS) |type=Report |date=1997-02-13 |orig-date=1995 |url=http://ww1.iucr.org/cexec/rep95/idcns.htm |access-date=2012-01-26 |url-status=dead |archive-url=https://web.archive.org/web/20090827091437/http://ww1.iucr.org/cexec/rep95/idcns.htm |archive-date=2009-08-27}} {{cite web |title=(IUCr) 1996 Report - IUPAC Interdivisional Committee on Nomenclature and Symbols (IDCNS) |type=Report |publisher=[[International Union of Crystallography]] |date=1997-02-14 |orig-date=1996 |url=http://www.chester.iucr.org/iucr-top/cexec/rep96/idcns.htm |access-date=2012-01-26 |url-status=dead |archive-url=https://web.archive.org/web/20130613121942/http://www.chester.iucr.org/iucr-top/cexec/rep96/idcns.htm |archive-date=2013-06-13}} {{cite journal |author-first=Bruce |author-last=Barrow |title=A Lesson in Megabytes |journal=IEEE Standards Bearer |volume=11 |date=January 1997 |orig-date=1996 |publisher=[[IEEE]] |page=5 |url=https://www.thierry-lequeu.fr/data/PELS/Comm/Publications/Newsletter/9704/STORY18.HTML |access-date=2022-12-24 |url-status=live |archive-url=https://web.archive.org/web/20220528124411/https://www.thierry-lequeu.fr/data/PELS/Comm/Publications/Newsletter/9704/STORY18.HTML |archive-date=2022-05-28}} "These prefixes for binary multiples, which were developed by IEC Technical Committee (TC) 25, Quantities and units, and their letter symbols, with the strong support of the International Committee for Weights and Measures (CIPM) and the IEEE, were adopted by the IEC as Amendment 2 to IEC International Standard IEC 60027-2: Letter symbols to be used in electrical technology – Part 2: Telecommunications and electronics." {{cite journal|url=http://journals.iucr.org/a/issues/2000/06/00/es0288/es0288bdy.html#SEC15.1 |title=IUCR 1999 report on IUPAC Interdivisional Committee on Nomenclature and Symbols |journal=Acta Crystallographica Section A: Foundations of Crystallography |date=November 2000 |volume=56 |issue=6 |pages=609–642 |publisher=Journals.iucr.org |doi=10.1107/S0108767300012873 |pmid=11058849 |access-date=2012-01-26}} IEC 60027-2 (2000-11) Ed. 2.0 {{Cite journal |title=Prefixes for binary multiples |author=A.J.Thor |journal=Metrologia |year=2000 |volume=37 |issue=81 |url=http://ej.iop.org/links/rDo33k,Nb/lrUHtuYE3BGiff6cav5vpA/me0112.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://ej.iop.org/links/rDo33k,Nb/lrUHtuYE3BGiff6cav5vpA/me0112.pdf |archive-date=2022-10-09 |url-status=live |doi=10.1088/0026-1394/37/1/12 |page=81 |bibcode=2000Metro..37...81T |s2cid=250774728 }}{{dead link|date=July 2017 |bot=InternetArchiveBot |fix-attempted=yes }} {{cite press release|date=2005-08-15 |title=HERE COME ZEBI AND YOBI |publisher=International Electrotechnical Commission |url=http://www.iec.ch/news_centre/release/nr2005/nr2005.htm |archive-url=https://archive.today/20070611071833/http://www.iec.ch/news_centre/release/nr2005/nr2005.htm |archive-date=11 June 2007 }} {{cite web |url=http://www.niso.org/publications/newsline/2008/newslinemay2008.htm#Spec4 |title=niso, New Specs and Standards |publisher=Niso.org |access-date=2012-01-26 |archive-url=https://web.archive.org/web/20081208131408/http://www.niso.org/publications/newsline/2008/newslinemay2008.htm#Spec4 |archive-date=2008-12-08 }} {{cite web|url=http://www.bipm.org/utils/common/documents/jcgm/JCGM_200_2012.pdf |archive-url=https://ghostarchive.org/archive/20221009/http://www.bipm.org/utils/common/documents/jcgm/JCGM_200_2012.pdf |archive-date=2022-10-09 |url-status=live|title=International vocabulary of metrology - Basic and general concepts and associated terms (VIM)|edition=3rd|website=Bipm.org|access-date=30 December 2017}} {{cite web |title=List of Resolutions for the 27th meeting of the General Conference on Weights and Measures |url=https://www.bipm.org/documents/20126/64811223/Resolutions-2022.pdf |archive-url=https://web.archive.org/web/20221118153958/https://www.bipm.org/documents/20126/64811223/Resolutions-2022.pdf |archive-date=2022-11-18 |url-status=live |date=2022-11-18 |access-date=2022-11-18 }} {{cite journal |title=How many yottabytes in a quettabyte?

They should not be used to indicate powers of 2 (for example, one kilobit represents 1000 bits and not 1024 bits). The IEC has adopted prefixes for binary powers in the international standard IEC 60027-2: 2005, third edition, ''Letter symbols to be used in electrical technology – Part 2: Telecommunications and electronics''. The names and symbols for the prefixes corresponding to 210, 220, 230, 240, 250, and 260 are, respectively: kibi, Ki; mebi, Mi; gibi, Gi; tebi, Ti; pebi, Pi; and exbi, Ei. Thus, for example, one kibibyte would be written: 1 KiB = 210 B = 1024 B, where B denotes a byte. Although these prefixes are not part of the SI, they should be used in the field of information technology to avoid the incorrect usage of the SI prefixes. |author=Bureau International des Poids et Mesures.}} {{cite web|url=http://www.sae.org/standardsdev/tsb/tsb003.pdf#page=33 |archive-url=https://ghostarchive.org/archive/20221009/http://www.sae.org/standardsdev/tsb/tsb003.pdf#page=33 |archive-date=2022-10-09 |url-status=live|format=PDF|title=Rules for SAE Use of SI (Metric) Units] – Section C.1.12 – SI prefixes|website=Sae.org|access-date=30 December 2017}} {{Cite web|url=http://www.cenelec.eu/dyn/www/f?p=104:110:1546953662480229::::FSP_PROJECT,FSP_LANG_ID:15306,25|archive-url=https://archive.today/20130213052907/http://www.cenelec.eu/dyn/www/f?p=104:110:1546953662480229::::FSP_PROJECT,FSP_LANG_ID:15306,25|archive-date=2013-02-13|title = CENELEC - Standards Development - List of Technical Bodies -}} {{Cite web|url=http://www.cenelec.eu/dyn/www/f?p=104:110:6177007965168887::::FSP_PROJECT,FSP_LANG_ID:20776,25|archive-url=https://archive.today/20120722151947/http://www.cenelec.eu/dyn/www/f?p=104:110:6177007965168887::::FSP_PROJECT,FSP_LANG_ID:20776,25|archive-date=2012-07-22|title = CENELEC - Standards Development - List of Technical Bodies -}} As used in this article, the term '''customary binary prefix''' or similar refers to prefixes such as kilo, mega, giga, etc., borrowed from the similarly named [[SI prefix]]es but used to denote a power of 1024. {{cite web|url=http://welcome.hp.com/country/us/en/welcome.html |title=Hewlett-Packard |publisher=Welcome.hp.com |access-date=2012-01-26}} {{cite web|url=http://www.sonystyle.com/webapp/wcs/stores/servlet/CategoryDisplay?catalogId=10551&storeId=10151&langId=-1&categoryId=16155&SR=nav:shop:computers:desktops:ss&ref=http://www.sony.com/index.php|title=Consumer Electronics - Sony US|website=Sonystyle.com|access-date=30 December 2017|archive-date=2011-06-16 |archive-url=https://web.archive.org/web/20110616080047/http://www.sonystyle.com/webapp/wcs/stores/servlet/CategoryDisplay?catalogId=10551&storeId=10151&langId=-1&categoryId=16155&SR=nav%3Ashop%3Acomputers%3Adesktops%3Ass&ref=http%3A%2F%2Fwww.sony.com%2Findex.php}} {{cite web|url=http://www.4allmemory.com/index.cfm?fuseaction=search.rdram_rambus_pc1066 |title=4AllMemory.com |publisher=4AllMemory.com |access-date=2012-01-26}} The term '''SI prefix''' or similar refers to prefixes such as kilo, mega, giga, etc., defined by the [[International System of Units|SI system]] of units and ''always'' used to denote a power of 1000; in other words, always as decimal prefixes. {{cite web |url=http://www.annodex.net/cgi-bin/man/man2html?units+7 |title=Units |access-date=2007-05-20 |date=2001-12-22 |work=[[Manual page (Unix)|Linux Programmer's Manual]] |quote=When the Linux kernel boots and says hda: 120064896 sectors (61473 MB) w/2048KiB Cache the MB are megabytes and the KiB are kibibytes. |archive-url=https://web.archive.org/web/20070902124532/http://www.annodex.net/cgi-bin/man/man2html?units+7 |archive-date=2 September 2007 }} {{cite web|url=https://lwn.net/2002/0103/a/esr-kibi.php3 |title=ESR post on LKML |publisher=Lwn.net |access-date=2012-01-26}} {{cite web|url=http://www.neowin.net/news/ubuntu-implements-units-policy-will-switch-to-base-10-units-in-future-release |title=Ubuntu implements units policy, will switch to base-10 units in future release |publisher=Neowin.net |access-date=2012-01-26}} {{cite web|url=https://wiki.ubuntu.com/UnitsPolicy |title=UnitsPolicy – Ubuntu Wiki |publisher=Wiki.ubuntu.com |access-date=2012-01-26}} {{cite magazine |url=http://www.macworld.co.uk/mac/news/index.cfm?RSS&NewsID=27034 |title=Snow Leopard's new maths |magazine=Macworld |date=2009-08-28 |access-date=2011-04-13 }}{{Dead link|date=May 2021 |bot=InternetArchiveBot |fix-attempted=yes }} {{cite web |url=https://support.apple.com/en-ca/HT201402 |title=How iOS and macOS report storage capacity |publisher=Apple Inc |date=2018-02-27 |access-date=2021-06-27}} {{cite web | author = JEDEC Solid State Technology Association | title = JEDEC Standard No. 100B.01 – Terms, Definitions, and Letter Symbols for Microcomputers, Microprocessors, and Memory Integrated Circuits | date = December 2002 | page = 8 | url = http://www.jedec.org/download/search/JESD100B01.pdf | access-date = 2010-03-07 | quote = The definitions of kilo, giga, and mega based on powers of two are included only to reflect common usage.
