11 Facts About Binary prefixes

Accordingly, the US National Institute of Standards and Technology requires that SI Binary prefixes be used only in the decimal sense: kilobyte and megabyte denote one thousand bytes and one million bytes respectively, while new terms such as kibibyte, mebibyte, and gibibyte, having the symbols KiB, MiB, and GiB, denote 1024 bytes, 1 bytes, and 1 bytes, respectively.

In 2008, the IEC Binary prefixes were incorporated into the International System of Quantities alongside the decimal Binary prefixes of the international standard system of units.

Compliance with the SI requires that the Binary prefixes take their 1000-based meaning, and that they are not to be used as placeholders for other numbers, like 1024.

The IEC Binary prefixes were defined for use alongside the International System of Quantities in 2009.

Different interpretations of disk size Binary prefixes has led to class action lawsuits against digital storage manufacturers.

Bruce Alan Martin of Brookhaven National Laboratory further proposed that the prefixes be abandoned altogether, and the letter B be used for base-2 exponents, similar to E in decimal scientific notation, to create shorthands like 3B20 for 3×2, a convention still used on some calculators to present binary floating point-numbers today.

Double Binary prefixes were already abolished from SI having a multiplicative meaning, and this proposed usage never gained any traction.

Names for the new prefixes are derived from the original SI prefixes combined with the term binary, but contracted, by taking the first two letters of the SI prefix and "bi" from binary.

IEC standard binary prefixes are now supported by other standardization bodies and technical organizations.

NIST has stated the SI prefixes "refer strictly to powers of 10" and that the binary definitions "should not be used" for them.

IEC Binary prefixes are used by Toshiba, IBM, HP to advertise or describe some of their products.
