A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics
    1. NEW RULE as of 5 Nov 2024, trying it out
    2. Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
    3. Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct-----

Despite being metric, Celsius is barely used with a prefix when describing temps high enough to warrant it (lemmy.world)

I suspect you may have mistaken me for the first poster in this comment chain. I never disagreed with your statement that precision is not a factor, I was clarifying only that they are not totally interchangeable. Interchangeable in relative measure yes, easy to convert in absolute measure yes, equally precise yes, but they are different things, albeit extremely similar.

I literally used the term precision in every post, it's what my initial is about, and you're just now telling me that's not what you were talking about? Also my first post I did not say they were perfectly interchangeable, I pointed out there is no loss of precision, and explicitly noted that you have to include the offset.

So now I'm confused as to why you chimed in at all.

No? I said as much in my very first comment.

But yes, the sizes of the units are the same.

And technically, that's only the case as of 2019, when Celsius was decoupled from the properties of water. Before that, kelvin was more precise, since it did not depend on controlling for pressure. Before 2019, there were precision discrepancies between K and °C.
