In this convention, one thousand and twenty-four kilobytes (1024 KB) is equal to one megabyte (1 MB), where 1 MB is 1024 2 bytes. In December 1998, the IEC addressed such multiple usages and definitions by creating prefixes such as kibi, mebi, gibi, etc., to unambiguously denote powers of 1024. [10]
Definition of prefixes using powers of 10—in which 1 kilobyte (symbol kB) is defined to equal 1,000 bytes—is recommended by the International Electrotechnical Commission (IEC). [28] The IEC standard defines eight such multiples, up to 1 yottabyte (YB), equal to 1000 8 bytes. [29]
~ 10 58 bits – thermodynamic entropy of the sun [29] (about 30 bits per proton, plus 10 bits per electron). 2 230: 10 69 ~ 10 69 bits – thermodynamic entropy of the Milky Way Galaxy (counting only the stars, not the black holes within the galaxy) [citation needed] 2 255: 10 77: 1.5 × 10 77 bits – information content of a one-solar-mass ...
When b is 2, the unit is the shannon, equal to the information content of one "bit". A system with 8 possible states, for example, can store up to log 2 8 = 3 bits of information. Other units that have been named include: Base b = 3 the unit is called "trit", and is equal to log 2 3 (≈ 1.585) bits. [3] Base b = 10
As 1024 (2 10) is approximately 1000 (10 3), roughly corresponding to SI multiples, it was used for binary multiples as well. In 1998 the International Electrotechnical Commission (IEC) published standards for binary prefixes , requiring that the gigabyte strictly denote 1000 3 bytes and gibibyte denote 1024 3 bytes.
The tenth power of 2 (2 10) has the value 1024, which is close to 1000. This has prompted the use of the metric prefixes kilo, mega, and giga to also denote the powers of 1024 which is common in information technology with the unit of digital information, the byte. Units of information are not covered in the International System of Units.

2. As used in IEEE Std 610.10-1994, the terms kilobyte (kB) means 2 10 or 1024 bytes, megabyte (MB) means 1024 kilobytes, and gigabyte (GB) means 1024 megabytes. Onto IEEE 610.10. :) — Omegatron 23:16, 11 May 2008 (UTC) IEEE 610.10 also lists both the decimal and binary definitions. — Omegatron 23:20, 11 May 2008 (UTC)
