I like that
100c and 100K = dead but for different reasons
We should really normalise the Japanese system - it makes as much sense as the European system and has the benefit of being “alphabetically” sortable.
I’m entirely for it.
Handwritten, I often use the military style 09 Oct 2023 just because the meaning is inarguable, but for files and such, it’s always YYYY-MM-DD.
I’d also like to see us adopt GMT, just calling noon and midnight whatever number they happen to be in our location. With remote work and jet travel, it makes sense.
And base-12 arithmetic, but that’s just a pipe dream.
Especially true if you include time as well:
Year > Month > Day > Hour > Minute
Vs
Day < Month < Year > Hour > Minute
What did Kevin ever do to Fahrenheit or Celsius?
Celcius is the logical choice. The others are just crazy.
Because aligning to the temperature at which water boils is the objectively correct choice?
“Hey, how hot is it going to be today?”
“Well water is about 1/3rd the way to boiling, so about 30 degrees”
When it’s “freezing cold” or “ice cold” outside, what do you think is freezing? When something is “boiling hot”, what is boiling exactly?
We use water to describe temperature even without using Celsius, because it’s everywhere around us, and we are literally made of this stuff. It’s also one of the only materials that goes through three different states in our usual temperature range, so using those as a reference point to measure temperature makes perfect sense imo.
The temperature of water is very intuitive in nature. Dip ur hand in ice water. That’s almost 0C. Dip ur finger in boiling water (very quickly). That’s 100C. Dip ur finger in coffee whose temperature is fit for consumption: that’s around 75-80C. Ur hot water shower is likely between 37 and 41C…
Everything is tied quite well to water. Now compare that to F. What’s 0F? What’s 100F?
Forget the intuitiveness of celsius. It’s also much easier to calculate using celsius. When I say “My coffee was worth 80 calories”, I’m referring to a measure called “KCal”, which is the amount of energy required to raise the temperature of 1 litre, or 1 Kg of water by 1C. So if u ate something worth 100Kcal, you consumed enough energy to heat 1L/1Kg of water from 0C (ice) to 100C (steam). The average human requires around 2500 KCal everyday. Which is equivalent to 2.5 liters of water. Pretty cool, huh…
Just a quick sidenote: KCal is still not an “SI” unit. “Joules” are what we use here, but that’s another story.
We used water to decide a lot of measurements. 1ml of water is = 1 gram. A gram of water is also equal to 1 cm^3. It’s a beautiful system in that way. Water surrounds us and gives us life, it has chemically interesting properties that make this planet function. Why shouldn’t we just base everything off of this one substance?
the Celsius nerds are mad at you, I guess. I love it when you see someone make a good point and the downvotes just pile on.
never change, reddit.
edit: they’re here! lol. hey guys! have fun with your storming the castle to defeat the evil Fahrenheit! make sure to prepare your spells, you don’t wanna get caught out when the negative values come out. 💕
It is so funny seeing Americans thinking that only nerds uses celsius, because they can’t fathom it themselves. It is like when you call 24 hour time “military time”, even though the majority of Earths civilian population uses it.
Check which temperature scale the device you posted your garbage reply with uses for its sensors.
the Celsius nerds are mad at you
You mean most of the world? Defending a backwards options never looks like a rational choice.
The fact that 99.5% of the global population uses it makes it the objectively correct choice.
The remaining .5% can keep bashing their heads against a wall if they like though
Not arguing for either unit here - use what you’re comfortable with and don’t be smug about it - but Americans are ~4-5% of the world and even if not all Americans use Fahrenheit, people in other countries (e.g. mine) still do.
Maybe ecause everyone uses it? Just so you know nobody even knows how fahrenhiet was defined first, everyone in the scientific community uses kelvin which is celsius but shifted so absolute zero is zero on it and the us actually uses si they just convert it to imperial so conversion between them is easier. There is point to imperial units other than its hard to switch between systems.
Kelvin and Celsius are the same, just offset onto absolute zero or the water freezing point
Yeah, often it is just way more convenient to use the Kelvin scale without any negative temperatures for some calculations and formulas then Celsius
Fahrenheit: how hot humans feel
Celsius: how hot water feels
Kelvin & Rankine: how hot atoms feel
Yeah, this gets repeated (by Americans) every time a discussion about temperature measuring systems comes up, but it is complete nonsense. The vast majority of Earth’s population are completely fine with measuring how hot they feel in celsius, it is only people who are unaccustomed to that system who thinks it is somehow unqualified to do that.
I lived for a third of my life in a country that uses Celsius, and the switch to Fahrenheit was not only seamless, it made much more sense to me intuitively. Whereas I was fine using Celsius, I don’t really want to go back.
American who lives in a country that uses C now.
20=frickin cold 30=swampy ass 40=nope
Not enough degrees of separation
20 isn’t cold at all, it’s perfectly warm.
10 is nippy, but you still warm up quick after a few minutes walking, and get sweaty if you’re working on something.
0 is cold enough for a couple layers. Jumper + jacket so you can take one off if you warm up too much.
-10 doesn’t feel that much different to 0.
-20 is time to put on a thicker coat over the jumper.
I don’t think how hot humans feel works at all, it’s just arbitrary
Can humans survive 100 degree heat? Yes so it doesn’t represent 100%
150 for 3rd degree burns (almost instant), does Fahrenheit go off base 150? Also no
What about cold? Well -40 requires a lot of layers, so then +40 should be pretty hot for humans right? Nope, because it’s not related to humans at all
I don’t think how hot humans feel works at all, it’s just arbitrary
Fahrenheit was originally calculated to be 64 even divisions between water freezing temp and human body temp, then 32 more units below freezing.
Then ambient human body temp was recalculated from 96F to 98.6F.
So it’s not exactly arbitrary. It’s based on powers of 2, based upon an inaccurate measurement.
I mean, the temperature 0 was assigned because it was the lowest temperature that winter in Fahrenheit’s town, and the “powers of two” was only chosen because it was simple to mark degree lines on his instrument. Feels quite arbitrary to me…

I have no idea what this means.

Why do these matter? What percentage of humans live where it’s regularly -40 degrees? Why does the scale need to be perfect in your opinion? And how is Celsius better?
I have no idea what this means.
Humans can survive 100 F so it’s not a scale of 0-100, which you would expect for a system based on humans
Why does the scale need to be perfect in your opinion?
The person I responded to said it was based off humans, I was arguing that it wasn’t because no patterns exist in relation to humans
And how is Celsius better?
Well the person claimed it’s based on the temperature of water at sea level with 0 being freezing and 100 being boiling. This would be the 0-100% for water
If farenheit represents how humans feel then 50 is the most comfortable temperature right?
0 should be the most comfortable, with less being cold and more being hot.
No one said it represents “100%”, whatever that is even supposed to mean. 100F is really hot outside. 0 F is really cold. Doesn’t have to make 100% sense. Celsius doesn’t make perfect sense either. There is no perfect magical scale that works completely.
100°F was supposed to be average human body temp. Guy who made the scale fucked up his math and we ended up actually at 98.6°F
Nah, that’s a myth. It’s actually a little more complicated than that, and the actual measurements changed over time.
