While we’re nitpicking, the post says multiple times that SI prefix symbols are “all uppercase except for kilo (k)”.
That’s just factually wrong. More than half of them are lowercase! There’s centi- ©, micro- (µ), nano- (n), etc. On the positive side there’s even deca- (da) and hecto- (h), though they aren’t particularly common or useful. I did at least see milli- (m) and bit (b) mentioned in a brief note though.
Obviously context matters and only the positive powers from kilo upward matter in computer science. But I studied chemistry and physics so I guess it irked me to see the statement repeatedly ignore all the negative powers of ten.
Overall, good rant though 😅 I’ll be more careful to use KiB and MiB from here out when appropriate.

Ok, I understand what you are trying to do, but I that is not how I read it at the time. Prefix to me in this context means e.g., “kilo” in “kilobyte”, and not the “k” in “kB”. I am not sure it is helpful to split the unit symbol up like that.

But the first part is called prefix even in the standard itself. I wanted to make that distinction because it’s not important what the base unit is. By speaking about prefixes instead of the unit as a whole I wanted to make it clear that you can (at least in theory) use any base unit. So everything I said about KiB and kB is also true for Kib and kb and even for kK (kilokelvin) and KiB (kibikelvin) 🤣

In terms of language you are correct. But in terms of SI usage it seems to me OP is expressing it correctly. The SI unit prefixes have a name, a symbol and a multiplier. The prefix is a concept that encompasses all three of those attributes. So “kilo” is one way of identifying the 10^3 unit prefix, but the name kilo is not the prefix itself. It’s just the name we use to refer to it. And the symbol k in km is certainly the unit prefix portion of that unit of measure.
