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

[edit]

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.

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 "metric prefixes", but that is an even vaguer category.) —Quondum 21:13, 21 December 2024 (UTC)[reply]
