Comment on temperature
EnderofGames@sh.itjust.works 2 months agoThe Fahrenheit scale was built around human biology. Nope, it was built around the highest and lowest extremes some dude could create in his room. Not based on human biology in the slightest. Don’t repeat this false information.
0C isn’t even that cold, and 100C is literally instant death. Yeah, but counter argument, who gives a shit? The “meme” doesn’t say anything remotely close to “from 0 to 100”. I don’t know why you are under the impression that these scales become inaccurate if you leave the 0-100 range. I live in a region that frequents -40C to +40C over a year- that’s centered on zero, so it’s already better for “how humans feel” than being centered on 32 and pretending there is some cosmic/celestial/god ordained reason for it.
Kelvin is the most scientifically objective scale, but also the least intuitive for humans… Still no one giving a shit- the “meme” doesn’t remotely even suggest anything related to this.
Be forewarned that I am willing to die on this hill I don’t know why you sign this off with “I’m an obnoxious twat”, but I’m perfectly happy with using the block function if the threat is real.

A) Fahrenheit has an appropriate level of granularity for humans
B) Fahrenheit has an intuitive frame of reference for humans
Celsius and Kelvin do not.
I don’t want to fight about this I just think it’s actually true, and I also think Europeans get insanely defensive about stuff like this for no reason.

A) So is Celsius, you do everything in double digits until you turn on your oven. B) If 50F was actually room temperature (the middle of too hot and too cold), I could agree. The fact that is is not means for me the intuition is learned and not natural. And that I have to learn a few anchorpoints to convert my own intuition when I ever visit the US.

Idk how your A relates to mine, if anything that’s more about the frame of reference, not the granularity. Let me try to clarify.
You have to use negative numbers more frequently with Celsius > Celsius has a less intuitive frame of reference (I will concede that at least it’s better than being in triple digits all the time like Kelvin)
Each Celsius degree is nearly two Fahrenheit degrees > Celsius is less granular
The reason I argue the more granular Fahrenheit is more intuitive is because a one degree change should intuitively be quite minor. But since you only have like 40 or 50 degrees to describe the entire gamut of human experiences with Celsius, it blends together a bit too much. I know that people will say to use decimals, but its the same flaw as negative numbers. It’s simply unintuitive and cumbersome.
B) 66F is room temperature. Halfway between freezing (32F) and 100F.
All scales have to be learned, obviously. It’s far easier to create intuitive anchorpoints in a 0-100 system than a -18 to 38 system. Thus, Fahrenheit is more intuitive for the average person.
I should note that if you are a scientist, the argument completely changes. If you are doing experiments and making calcualtions across a much wider range of temperatures, Celsius and Kelvin are much more intuitive. But we are talking about the average human experience, and for that situation, I maintain Fahrenheit supremacy

Your point about intuition is moot, imo, because if you didn’t grow up with F it’s just as unintuitive as C is to you.
When you’re used to it the usage of decimals and negative numbers is neither complicated nor unintuitive because you’ve learned to know this intuitively for your whole life.
I could argue, that freezing temps outside being below 0 are unintuitive because it’s obvious to me that negative temps mean it’s literally freezing cold. That’s intuitive for me because I‘ be used that my entire life. Same as room temperature being 20°C. It just makes sense to me because I‘ve always know it that way.
Your “intuitive anchor points” 32 or 66 or whatever are completely nonsensical and unintuitive to someone whose brain is wired in Celsius. Because we don’t think in -18 to 38 but rather -20 to 40, if you want to think of it like that (or -40 to 20 I suppose, if you live somewhere where it’s colder). But in all honesty, in my day to day life, I don’t think about that, because I just know what a celsius value means intuitively.
Fahrenheit is more intuitive for the average American, not the average person.

true.
false.

Sure, water is a really good system and it works well.
And for F that range is -40 to 104. See how you get 64 extra degrees of precision and nearly all of them are double digit numbers? No downside.
Furthermore F can use its base 10 system to describe useful ranges of temperature such as the 20s, 60s, etc. So you have 144 degrees instead of just 80, and you also have the option to utilize a more broad 16 degree scale that’s also built in.
You might say that Celsius technically also has an 8 degree scale(10s, 30s), but I would argue that the range of 10 degrees Celsius is too broad to be useful in the same way. In order to scale such that 0C is water freezing and 100C boiling, it was necessary for the units to become larger and thus the 10C shorthand is much less descriptive than the 10F shorthand, at least for most human purposes.

copy pasting now are we? here was my response to the same copied comment:
As you might imagine I completely disagree.
For my purposes 20’s, 30’s, negative 10’s and so on is perfectly good, and I would describe my purposes as human.
Again, this is based on your, and my, learned reference points. Of course you feel the scale of the farenheit is better suited for describing your life, those are your learned reference points.
I have my own learned reference points based on the Celsius scale I grew up with and, suprise suprise, to me they’re superior.

Unlike Americans, celsius users are not afraid of decimals, which fullfills all your graularity needs if you have them. But mostly it isn’t even needed because you literally cannot feel the difference.

You’ve provided zero proof of either statement.
