{{Quantities of bytes}}
'''Mebibita''' ([[bahasa Inggris]]: '''''mebibyte''''') adalah satuan kelipatan [[bita]] yang digunakan untuk mengukur kuantitas informasi digital. Simbol unit untuk mebibita adalah '''MiB'''.
'''Mebibyte''' adalah satuan multiple [[byte]] yang digunakan untuk mengukur kuantitas informasi digital. Mebibyte berasal dari kata '''mega''' dan '''biner''', sementara kata ''byte'' merupakan satuan informasi digital. Jadi mebibyte berarti 2<sup>2</sup> x 2<sup>10</sup> = 2<sup>20</sup> byte, atau sama dengan 1 048 576 bytes. Simbol unit untuk mebibyte adalah '''MiB''' <ref>{{cite web

Satuan ini dibuat oleh [[International Electrotechnical Commission|IEC]] (IEC) pada tahun 2000 dan telah diterima oleh hampir semua organisasi standar. Satuan ini didesain untuk menggantikan [[megabytemegabita]] yang digunakan dalam bidang ilmu komputer untuk menunjukkan 2<sup>20</sup> bytesbita, yang sama dengan [[International System of Units|SI]] definisi dari prefiks [[megaMega-|mega]].
 
== Definisi ==
: 1 MiB = 2<sup>20</sup> [[bytebita]]s = 10241.024 [[kibibytekibibita|KiB]]s = 1 .048 .576 bytes[[bita]]
 
Prefiks '''Mebi''' adalah berasal sebagai [[portmanteau]] dari kata '''me'''ga dan '''bi'''ner, menunjukkan asal-usulnya dalam kedekatan dalam nilai SI awalan mega (10<sup>6</sup>)

The prefix ''mebi'' is a [[binary prefix]] derived from the words mega and binary, indicating its origin in the closeness in value to the [[SI prefix]] ''mega''. A ''mebibyte'' (abbreviated MiB) is 2<sup>20</sup> (i.e., 1024 x 1024) bytes,<ref>{{cite web|url=http://www.pcmag.com/encyclopedia_term/0,2542,t=mebi&i=55970,00.asp |title=Definition of NIST binary |publisher=Ziff-Davis |date=2010 |accessdate=2010-07-31}}</ref> or 1,048,576 bytes in decimal terms. One MiB thus differs from one [[megabyte]] (abbreviated MB), which means 10<sup>6</sup> (i.e., 1000 x 1000 = 1,000,000) bytes.
 
''Mebibyte'' is not commonly used. Instead, ''megabyte'' is often used to mean 1000 x 1000, 1024 x 1024, and even 1000 x 1024 bytes. Such usage can be confusing and inconsistent. For example, Microsoft's [[Windows XP]] [[operating system]] shows a file of 2<sup>20</sup> bytes as "1.00 MB" in its file properties [[Dialog box|dialog]], while showing a file of 10<sup>6</sup> ({{gaps|1|000|000}}) bytes as 976 KB; but [[Apple Inc.|Apple]]'s [[Mac OS X]] 10.6 would report a 10<sup>6</sup> byte file as 1 MB.<ref>{{cite web|url=http://support.apple.com/kb/TS2419 |title=How Mac OS X reports drive capacity |publisher=Apple Inc |date=2009-08-27 |accessdate=2009-10-16}}</ref>.
 
==History==
Confusion in the meaning of ''megabyte'' was evident for many years. For instance, the [[1.44M#Ultimate_capacity_and_speed|1.44 MB floppy disk]]'s storage capacity was calculated using {{gaps|1|024|000|bytes}} per "MB" (i.e. 1.44×1024×1000), rather than 1.47 MB (1.47×1000×1000) or 1.40 MiB (1.40×1024×1024).
 
The ''mebi-'' prefix was defined by the [[International Electrotechnical Commission]] (IEC) in December 1998. It is perhaps becoming gradually accepted. For example, the interpretation of a 10<sup>6</sup> byte file as 1 MB did not appear in versions of [[Apple Inc.|Apple]]'s [[Mac OS X]] before version 10.6.
 
The use of ''mebibyte'' and related units is presently endorsed by the [[Institute of Electrical and Electronics Engineers]] (IEEE) and the [[International Committee for Weights and Measures]] (CIPM) in contexts where use of a [[binary prefix]] makes sense.
 
==Discussion==
In [[The Art of Computer Programming]], [[Donald Knuth]] proposed that the unit now represented by MiB be called a ''large megabyte'' (abbreviated ''MMB'').
