IEEE 1541-2002 - Acceptance

Acceptance

In 1998, the International Bureau of Weights and Measures (BIPM), one of the organizations that maintain SI, published a brochure stating, among other things, that SI prefixes strictly refer to powers of ten and should not be used to indicate binary multiples, using as an example that 1 kilobit is 1000 bits and not 1024 bits.

The binary prefixes have been adopted by the European Committee for Electrotechnical Standardization (CENELEC) as the harmonization document HD 60027-2:2003-03 and therefore they are legally binding in the EU. This means that legally there is no confusion because it is clearly defined that binary prefixes have to be used for powers of two and SI prefixes only for powers of ten. This document has been adopted as a European standard.

Despite the presence of the standard and organization adoption, the new binary prefixes are only gaining acceptance slowly. The SI prefixes for binary multiples have been in use for many years, new operating systems and applications still use them.

Supporters of IEEE 1541 emphasize that the new standard solves the confusion of units in the market place. Some researchers and software (most notably free and open source) have embraced the standard and use the decimal SI prefixes and new binary prefixes according to the standards.

Famous quotes containing the word acceptance:

    One of the oddest features of western Christianized culture is its ready acceptance of the myth of the stable family and the happy marriage. We have been taught to accept the myth not as an heroic ideal, something good, brave, and nearly impossible to fulfil, but as the very fibre of normal life. Given most families and most marriages, the belief seems admirable but foolhardy.
    Jonathan Raban (b. 1942)

    Devout believers are safeguarded in a high degree against the risk of certain neurotic illnesses; their acceptance of the universal neurosis spares them the task of constructing a personal one.
    Sigmund Freud (1856–1939)

    Nothing, neither acceptance nor prohibition, will induce a child to stop swearing overnight. Teach your child respect for himself and others, that profanity can hurt, offend, and disgust, and you’ll be doing the best you can...And save your parental giggling over mispronounced curses for after the children’s bedtime.
    Jean Callahan (20th century)
