== Multiple of a unit of measurement by an integer power of two?? ==
== ISO is more recognizable than IEC ==


WRT "A binary prefix is a unit prefix that indicates a multiple of a unit of measurement by an integer power of two". Is it? Or is it a power of 1024? Yes, they are all powers of 2, but calling them that seems misleading. That they are power of 2 doesn't seem like the most central defining property of this set of multiples. ] (]) 20:57, 21 December 2024 (UTC)
I propose that all references in the article and the tables to IEC binary prefixes should be modified to refer to ISO binary prefixes or ISO/IEC binary prefixes. ISO is simply more recognizable than IEC. ] (]) 18:49, 28 January 2024 (UTC)


: If we had names for other powers of two, they too would be called binary prefixes. The fact that we find only a certain subset of these prefixes convenient enough for general use to create a name does not mean that we should necessarily use the smallest (obvious) category that contains this subset. And no, it is not misleading: it is predicated on the practicality of implementing memory sizes as powers of 2, not of 1024. When the prefixes 'centi', 'deci', 'deca' and 'hecto' fall into disuse, will it be misleading to call the remaining prefixes (all of which are powers of 1000) "decimal prefixes"? (Actually, these are more commonly called "]es", but that is an even vaguer category.) —] 21:13, 21 December 2024 (UTC)

::{{ping|Stevebroshar}} has a valid point. ''Binary prefixes'' historically are defined in positive integer powers of 1024 and are likely to continue to do so. They go back to the approximate equivalence of 1,024 to 1,000 and unlike metric prefixes are not defined for each power of the base number to a maximum and not to a minimum at all. Whether the rarely used metric prefixes fall into disuse or not is irrelevant, they would remain defined. I think we would have to find an RS to change the article to state "positive integer powers of 1024" but with one I would support such a such a change. ] (]) 20:22, 22 December 2024 (UTC)

Multiple of a unit of measurement by an integer power of two??

WRT "A binary prefix is a unit prefix that indicates a multiple of a unit of measurement by an integer power of two". Is it? Or is it a power of 1024? Yes, they are all powers of 2, but calling them that seems misleading. That they are power of 2 doesn't seem like the most central defining property of this set of multiples. Stevebroshar (talk) 20:57, 21 December 2024 (UTC)

If we had names for other powers of two, they too would be called binary prefixes. The fact that we find only a certain subset of these prefixes convenient enough for general use to create a name does not mean that we should necessarily use the smallest (obvious) category that contains this subset. And no, it is not misleading: it is predicated on the practicality of implementing memory sizes as powers of 2, not of 1024. When the prefixes 'centi', 'deci', 'deca' and 'hecto' fall into disuse, will it be misleading to call the remaining prefixes (all of which are powers of 1000) "decimal prefixes"?

@Stevebroshar: has a valid point. Binary prefixes historically are defined in positive integer powers of 1024 and are likely to continue to do so. They go back to the approximate equivalence of 1,024 to 1,000 and unlike metric prefixes are not defined for each power of the base number to a maximum and not to a minimum at all. Whether the rarely used metric prefixes fall into disuse or not is irrelevant, they would remain defined.
