else, say 3, I think you'll agree that it is erroneous to claim that 3 km should be equal to 3 km Ă— 3 km which would be 9Ă—10 m. I would request that someone more expert or confident than me update this example to at least be less ambiguous if not more correct. We are simply trying to convey that "prefixing" binds more tightly than exponentiation (which of course binds more tightly than multiplication).

It's not out of ignorance, nor because of limitations of the keyboard (these are real, but circumvented in other ways). Instead, I believe 'mcg' is widely used by medics when prescribing drugs in tiny doses, because they fear 'ÎĽg' can result in an overdose if mis-read as 'mg'. I think this is worth

I think this is either perfectly ambiguous and/or wrong: "1 km denotes 1 km × 1 km = 10 m, not 10 m"; I think it should be written more like "3 km denotes 3 (km × km) = 3 × 10 m, not 3 × 10 m" (and also not 9 of anything). An an example of "1×1" is ambiguous, and if you change the 1 to something

In 2010 to 2015, someone suggests “xona” or “xenta” for 10, and for another prefix starting with x (e.g. “xono” or “xento”) for 10, but not approved by SI (if they are approved, then possibly “wecra” for 10 and “wecro” for 10), why in 2022 someone suggests “ronna” and “quetta” for 10 and 10 and

I consider this to be typical US government behavior. One agency, the FDA, just defies the law and NIST (which is part of the
Commerce Department) by unilaterally proposing a change to SI rather than working with NIST or lawmakers to fix the problem. This is much the same as when law makers,

The abbreviation "mcg" is in some situations an alternative for ÎĽg, but "mc" cannot be used in combination with other units. So "mc" is not a prefix, it has no place in this general article. The abbreviation "mcg" is mentioned specifically in the microgram article, that's enough.

If it there is an accepted exception to the SI style guide rule in common use in some situations, then surely that needs covering in the article, regardless of the reason for using it (ignorance, arrogance, safety concerns, typographical considerations, clarity, or whatever). --

If we were going to add something to the article, it would be nice to find a good source that indicates whether this only occurs in the US, or if it is done in many countries.
