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) |

The article say ''"IEC proposed kibi, mebi, gibi and tebi, with the symbols Ki, Mi, Gi and Ti respectively"'', so, let's add some few examples |
|
|
:* 1024 meters is '''1 KiM''' (not lower "kim") |
|
|
:* 1024² meters is '''1 MiM''' |
|
|
:* ... |

: 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) |

Not popular, not used yet (the need it), but a binary prefix is for it. It is the intention of the binary prefixes. ] (]) 23:26, 30 April 2023 (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) |

:Although the prefixes are intended for any unit, it would not be in the way you suggest. The only example I can think of in the wild (other than for bit or byte) is the kibihertz (KiHz). For the metre it would be Kim (for kibimetre) and Mim (for mebimetre). ] (]) 07:58, 1 May 2023 (UTC) |
