1923: "Felsius"

[moody7277]

Title Text: The symbol for degrees Felsius is an average of the Euro symbol (€) and the Greek lunate epislon (ϵ).

Based on today's exchange rate, one degree Felsius is about a buck twenty.

[BrianK]

I think the better compromise is to use 0 for the freezing point of water and 200 for the boiling point. The Fahrenheit people get to keep their body temperature and "nice" weather numbers. The Celsius people get to keep "negative == ice" and scientifically supported definition.

That should reduce heating and cooling costs quite a bit.

I'd have named it "Celsenheit" .
Not to be confused with "Gesundheit"
Also not to be confused with "Celsenblue"

[Heimhenge]

Why stop with averaging just Celsius and Fahrenheit? Throw Rankine and Kelvin into the mix too. Call it RKCF. I leave the formula as an exercise for the reader.

[faubiguy]

The corresponding absolute scale is the Rankelvin, with the symbol °K for maximum confusion. 1 °K = 7×K / 5 = 7×°R / 9.

[tempest69]

At least -40 is the same for all three.

I like that Fahrenheit has 180 degrees of liquid water. It makes Degrees seem like a reasonable term to use.

I hate "degrees Celsius " Centigrade is a much better word (meaning measured in hundredths), "degrees Celsius" make me think that someone hasn't really considered how this works, and are just parroting down a long line of parrots.

[Rombobjörn]

I'd have named it "Celsenheit" .

Great, now we'll have an unresolvable schism between users of "Felsius" and users of "Celsenheit".

I think "funnygrade" is a much better word than "Fahrenheit".

The felsius symbol is simply a kyphotic F.

[Pfhorrest]

So should a minute of temperature be 1/60th of a degree, and a second be 1/60th of that again?

Better question: is 360°F = 0°F?

Yes, "degrees centigrade" is so much better than "degrees Celsius" because it removes the ambiguity around what scale the degrees are based on /sarcasm

For those fans of "gradians" for angular measurement, perhaps Felsius should use "gradees" or "degrians"?

[orthogon]

"Felsius" sounds obscene to me. Like it's the fancy Latinate term for "felching".

I hope you're not going to be so timid as to use the arithmetic mean for RKCF.

(Relvin, was to have been my suggestion. )

((And I knew exactly what the comic would be about, just by the title. I think that's good. Not sure for who, though.))

While an abbreviation could do, I propose "Rankelsienheit" as an alternative.

Bless you.

But isn't it supposed to be "Celsius" anyway, not "degrees Celsius".

I thought 0 °F was defined as the temperature you get when you pour salt on ice until the ice gets so cold it stops melting -- which Mr. Fahrenheit thought was a good choice because it is a very specific temperature, and so makes a better reference than the melting point of pure water. Which makes 0 °F more scientifically sound than 0 °C.

I don't know what the reference for 100 °F is supposed to be, though.

[keithl]

Planck units. The Planck temperature is 1.4168e32K, also known as an "absolute hotness" of 1.0. That way, if anyone asks you the temperature, you can say "close to zero" and be right every time - even if you are at the core of an exploding supernova.

Added note: It is about 2 microyoctoPlancks outside today. If it drops to 1.9 microyoctoPlancks, I'll put on a heavy coat.

[Yablo]

Centigrade should only be allowed 100 total degrees. I don't care where the 0 and 100 reference points are placed or how large the units are, but "110 degrees Centigrade" should be the temperature equivalent of "giving 110%."

I don't know what the reference for 100 °F is supposed to be, though.

I believe it was supposed to be body temperature, originally. But if that's true, I'm not entirely sure how it ended up being off, slightly.

(Checking Wikipedia: oh, it's much worse than that. Apparently he was was basing it on body temperature, but he was trying to make that come out to 96, so it would be three times the difference between his zero and the freezing temperature of water...)

Which makes 0 °F more scientifically sound than 0 °C.

It's unlikely that was the original definition, because salt water can have a freezing temperature below 0ºF. Fixed points of 32 and 96 (for axial body temprature) aren't bad, because there's 64º between them and powers of two are more useful for making instruments than powers of ten.

On the basis that Fahrenheit was a good instrument maker, Veritasium suggests in a video that the size of the ºF was chosen so that mercury would expand by a factor of 1 in 10,000 for each degree increase. (And given that we make thermometers with mercury rather than water, I don't see how a mercury-based definition is any less "scientific" than a water-based one.)

[keithl]

Melting point and boiling point of ... water? Those temperatures are only "standard" at 101 kPascal (one "standard" atmosphere of dry nitrogen/oxygen). At very high or very low pressures, where 99.99% of the water in the solar system can be found, the temperatures are different. Even on Earth, most liquid water is deep in the ocean. In the Kuiper belt and Oort cloud, where most of the "water surface" is (and where most intelligence will reside someday, better heatsink and more easily focused sunlight), the ambient pressure is so low that ice sublimates rather than melts.

Temperature should be expressible in universal, not geocentric, units.

The symbol has to have the degree sign, though, otherwise it's Coulombs. Given that, it's not clear how you can not pronounce the "degrees" part.

[Petrograd]

The symbol should be Ð. D is between C and F, and the extra - helps show it's supposed to be half way to E.

Alternatively, it should be D♯, borrowing from musical notation.

[ozuraravis]

What debate? The US is wrong and everyone else is right.

[chridd]

NOOOOOOOOO no no no no.. Degrees Centigrade??!?? Just Centigrade **you monster**

...but the question of whether to say "degrees" is separate from the question of whether to use Celsius or Centigrade. If it's the "degree" part that you object to, why not just say Celsius without the degrees? (I think I grew up calling it "degrees Centigrade", but I can't remember for sure.)

Also: degrees Kelvin

By the way, I just added Felsius here (under "less serious"), so now you can convert between Felsius and every other temperature system I could find when I first made that page.

[Soupspoon]

(Missed this.)
I demand the right to add Delisle into the averaging!
(edit: This demand made prior to seeing °D listed on the prior poster's calculation page. Nice to see some attention paid tothis much underused measure!)

But isn't it supposed to be "Celsius" anyway, not "degrees Celsius".

It's useful to differentiate the difference betweens the usages:
1) "degrees Celsius(/Centigrade/Fahrenheit/Kelvin/Romer/Reaumur/Delisle/etc)"
2) "Celsius(/Centigrade/Fahrenheit/Kelvin/Romer/Reaumur/Delisle/etc) degrees"

There are some technical issues that might be pointed out with various of the sub-forms, but the overriding thing is the difference between the two form-types. (Also written as °C vs C°, or alternate alphabetic element, to indicate the context.)

Obviously it should use the arithmetic-geometric mean.

[sotanaht]

Fahrenheit for weather, Celsius for water. It's what they were made for and what they are good at.

Think about the usable portion of the scale. Where I live 0°F and 100°F are about equally common. We very very rarely use numbers above 100 or below 0, but they do happen occasionally. In Celsius that would be a scale from -18 to 38, which is utter nonsense.

Curious what specific floating point errors you're seeing? (I know there are some, but are there some that you're seeing that I'm not aware of? Or if I wasn't clear enough about the "radians Fahrenheit/Celsius" options? In any case, putting "switch to using rational numbers" on my mental to-do list.)

[ucim]

I'd've gone the other way... "Felsius" doesn't use enough of the "Fahrenheit"; I'd've called it "Fahrsius".
Not to be confused with "fahrvergnügen".
