What is 0°F in terms of the human body? I’m guessing that 100°F is supposed to be a normal human body temperature, but in reality that will vary from person to person and everybody I’ve met is usually 97-99 unless they have a fever.
In Celsius/Centigrade, 0° is the freezing point of water at 1 atmosphere of pressure, and 100° is the boiling point.
In Kelvin, 0 is absolute zero, and it scales with Celsius/Centigrade because anchoring it to water just makes sense.
Fahrenheit is fucking silly and people only defend it because it’s what they were familiar with growing up, so they teach the next generation the same thing, thus perpetuating the cycle of tradition for the sake of tradition.

From Wikipedia:
———————
Several accounts of how he originally defined his scale exist, but the original paper suggests the lower defining point, 0 °F, was established as the freezing temperature of a solution of brine made from a mixture of water, ice, and ammonium chloride (a salt).[2][3] The other limit established was his best estimate of the average human body temperature, originally set at 90 °F, then 96 °F (about 2.6 °F less than the modern value due to a later redefinition of the scale).[2]
———-
Any measurement of temperature is going to be relative to the atmospheric pressure among other variables… I’m not a scientist but Celsius is just as random… it may make more sense because freezing water and boiling water make sense to you with a refrigerator and stove… for most of human history this would not have made any sense……
There’s uses of metric that make a lot more sense, it is not my intention to defend imperial systems of measurement or whatever they are called, it is interesting to me though….
What are the measurements we can define where if we met a completely alien race from another solar system where we could immediately agree on the system… that’s probably the best one lol
Kelvin does make sense with the absolute zero thing, in my opinion at least… now I need to look up if there is a maximum temperature. And whether it matters lol… matter would probably fall apart at that temperature in which case it doesn’t matter anyways haha (edit: I just learned that Kelvin uses the same scale as Celsius apparently)

There is a theoretical max temperature, the Planck Temperature ≈ 1.416 x 10^42 K. It’s the temperature at which the wavelength of emitted light is the Planck length.

Simplified: A black hole is the result of density – how much mass you cram into how little space. If something is heavy enough, even light passing near it gets pulled in and swallowed, so there’s some area where no light escapes: a black hole.
The difficulty is that you need a lot of gravity to bend the course of light. Gravity gets stronger the closer you get to the center, so at a certain distance, it will be strong enough no matter how little mass the object has.
But most objects are simply too large: Light will bounce off without ever getting that close to the center. You’d need to squeeze them together real hard to make them small enough, but there are other forces trying to keep them in shape that will resist you.
What you mean with “a whole lot of stuff” is the way more stable black holes work in space: A bunch of stuff so heavy that its own gravity is stronger than the forces trying to keep shape. If it’s strong enough, it can pull itself together so close that it gets smaller than that distance. Thus, there’s now an area around it where light can be trapped.
If you involve quantum physics, things get fucky, and supposedly there actually is some radiation still escaping, which is what the other post referred to, but I’m out of my depth there. There are also different types of black holes with their own complications, a bunch of details I skipped and a lot more I don’t even know.

I agree with you, except that I think the time system is great. It was deliberately designed to be maximally divisible, and makes a lot of sense in that manner. 12 hours of daylight— a highly divisible number, with 60 small (minuscule, or “minute”) divisions of the hour, which is even MORE divisible than 12. Then when time keeping got more accurate, they added a second division of 60 more parts, and… well, called ‘em seconds.
Basically, 12 and 60 are just so divisible they make really good bases.

The freezing and boiling points of water are by far the most logical reference points since anyone who wants to calibrate a thermometer will have access to water, and needs only go to the nearest ocean and bring some water to freezing and then boiling and making marks at each.

They are both random and arbitrary. Using the human body as a standard is probably useful for medical purposes… using water as a standard is probably useful for other purposes…
Considering temperature itself is dependent on other variables like atmosphere, any temerature system is going to be random and arbitrary…
Kelvin at least has a theoretical bottom for the coldest something can get maybe? But still, Kelvin is also arbitrary because it uses Celsius as a standard, which is random and arbitrary…
Why would you use a complex molecule like water? Why not hydrogen? Why would you use one earth atmosphere as a standard? Why not a vacuum?

If you involve quantum physics, things get fucky, and supposedly there actually is some radiation still escaping, which is what the other post referred to, but I’m out of my depth there. There are also different types of black holes with their own complications, a bunch of details I skipped and a lot more I don’t even know.
Space is awesome and big and full of nothing and tons of tiny, really fascinating bits of not-nothing sprinkled in, and we could spend our entire lives studying it and never know just how much we don’t.
That sounds like a misconception based on the misconception that the Planck Length is the smallest distance possible. Admittedly, I dropped out of physics 10 years ago so I might have no idea what I’m talking about.
About the maximum temperature.

Actually both freezing and boiling vary depending on your altitude…
I agree with you, except that I think the time system is great. It was deliberately designed to be maximally divisible, and makes a lot of sense in that manner. 12 hours of daylight— a highly divisible number, with 60 small (minuscule, or “minute”) divisions of the hour, which is even MORE divisible than 12. Then when time keeping got more accurate, they added a second division of 60 more parts, and… well, called ‘em seconds.
Basically, 12 and 60 are just so divisible they make really good bases.
That’s really interesting thanks
huh? how is the freezing point and boiling point of water made up? how is the temperature of the human body better in any way?
The freezing and boiling points of water are by far the most logical reference points since anyone who wants to calibrate a thermometer will have access to water, and needs only go to the nearest ocean and bring some water to freezing and then boiling and making marks at each.
Celsius is the precise opposite of random.
They are both random and arbitrary. Using the human body as a standard is probably useful for medical purposes… using water as a standard is probably useful for other purposes…
Considering temperature itself is dependent on other variables like atmosphere, any temerature system is going to be random and arbitrary…
Kelvin at least has a theoretical bottom for the coldest something can get maybe? But still, Kelvin is also arbitrary because it uses Celsius as a standard, which is random and arbitrary…
Why would you use a complex molecule like water? Why not hydrogen? Why would you use one earth atmosphere as a standard? Why not a vacuum?
It’s all random and arbitrary, sorry if you can’t see it.
okay so yes you’re not serious and just trying to get a rise out of people, great to have that confirmed.
Not sure what you are talking about but ok I guess lol
Crickets in Antarctica be like: prihc
And people say farenheight doesn’t have a use…
In Celsius it is chirps in 8 seconds + 5 (Dolbear’s Law), but if you listen a single “Chirpffffffsss”, than better stay at home
About half the time and an easier addition? Metric wins again.
As always, metrics with clear rules are always better as random metrics by bodyparts of an King in the past, apart avoiding errors. Ask the NASA, crashing 2 Mars probes using the Imperial system.

What use is the Fahrenheit measurement though? I thought only one or two countries use it.
US and … maybe Israel? Those are the two countries that use the US “Simple English” while the rest of us know what a U is for and how to say Z… so if they also both used F that would track.
Two countries and crickets apparently.
Just as God intended
This is bullshit
Am I the only one who thought that was a really shiny grasshopper?
