Americans always regurgite the “Fahrenheit is how people feel” nonsense, but it is just that: nonsense. Americans are familiar with fahrenheit so they think that it is more inituitive than other systems, but unsurprisingly people who are used to celsius have no problems using it to measure “how people feel” and will think it is a very inituitive system.
Can confirm. Moved from the US to Canada and maybe a year of using Celcius revealed to me just how fucking stupid and convoluted Fahrenheit is. My dad spent three weeks out here and started using Celcius on his phone. Now I only use Fahrenheit when dealing with fevers or temping cases of suspiciously overripe produce.
Fellow Americans. Celcius is superior and more intuitive for those who take a moment to adjust to it. It is okay to accept this as fact without developing an inferiority complex. USA not always #1. USA quite often not #1 and that is okay. It is okay for USA to not be #1 without developing an inferiority complex.
Fahrenheit is European.
I use it and I am not European.
Fahrenheit has a fine granularity that is lost in cold climates. It’s why the Bahamas/Belize use it as well.
Well you know that you can use the decimals?
How is - 40.000001°F more fine than - 40.00000000001°C?
23°C is a nice room temperature.
18°C is a bit chilly but still a comfortable temperature.
If you want to go for a finer destinction then we cann say 18.5°C is warmer but I personally can’t feel the difference.
Slightly off topic, but 23°C is a nice room temperature? We have our thermostats at 20°C and I find it quite warm. In the sleeping room we have 18°C and so do I have in my office, which I find quite comfortable. I hate visiting my parents, they always have 22.5°C which I find uncomfortably warm.
Well it’s all subjective after all, I’ll be happy about chilly 23°C inside when summer comes.
I can feel the difference between 71 and 73 in my house.
At 73, my kids room is uncomfortably hot. At 71, it has a perfect chill for sleeping.
Dude 71 is way too warm for sleeping, try 64-65 its healthier.
I don’t know if my thermostat is just wrong or if the layout of my house makes it inaccurate, but 64-65 in my house is frigid.
Plus we have a baby so 67-68 is really the lowest we could go at night I think.
But I agree, I sleep better in general when the blankets are warm and the house is cold!
Well it’s all subjective, I guess. Also depends on where you live.
I like that Fahrenheit has a narrower range for degrees. 1C is 1.8 degrees F. So, F allows you to have more precision without the use of decimals. Like, 71F feels noticeably different to me than 64F, but that is only a 3.8 degree difference in C.
But that also doesn’t matter because the granularity is meaningless if you don’t make decisions for differences between 71F and 70F
Not at those exact temperatures, but one degree matters in in grilling meat, making mash for beer, making candy, etc.
Sure, but you should be using Celsius for those things. That’s the main argument here.
Celsius is more intuitive for like science or lab work but for day to day use either one is really arbitrary based on what you’re used to.
I mean, you’re 100% wrong. Fahrenheit isn’t “how people feel” arbitrarily, it’s almost literally a 0-100 scale of how hot it is outside. You need no prior knowledge to interpret a Fahrenheit measurement. Which really reflects poorly on everyone who says “Fahrenheit doesn’t make any sense” because if they were capable of any thought at all they would figure it out in 2 seconds, like everyone else. I’m a lab rat that uses Celsius all day every day, I’m just not a pretentious stuck up tool about alternate measurements just because I refuse to understand them.
It is really easy to map onto human feel though. 0-100 pretty accurately maps onto our minimum and maximum realistically survivable temps, long-term, and the middle temperatures of those are the most comfortable. It’s far more round, when it comes to describing human preference and survivability, than Celsius is.
I bet a lot more people know what 0°C feels like than 0°F. One is freezing point, one is a completely arbitrary temperature which only gets called “the lowest you’ll experience” as a post hoc rationalisation of Fahrenheit. Most people will never experience anything that cold, some people experience colder.
I even bet more people know what 100°C feels like than 100°F. One is accidentally getting scalded by boiling water, the other is a completely arbitrary temperature which is quite hot but not even the hottest you’ll experience in America.
boiling water isnt necessarily 100c. if youre boiling water, it can be any arbitrary temperature above 100.
thats like going to a geyser pit and saying thats 100c, when it isnt. when you cook and let water come to a boil, the chef doesnt care that its exactly 100c, only that its in the state above 100.
If anything it’ll be below 100 due to altitude. For example salt water for making pasta boils still at approx 100 deg. C. It takes quite a lot of salt (way more than you would ever want to consume) to meaningfully raise the boiling point.
if youre boiling water, it can be any arbitrary temperature above 100.
That’s not how boiling works. The water heats up to its boiling point where it stops and boils. While boiling the temperature does not increase, it stays exactly at the boiling point. This is called “Latent Heat”, at its boiling point water will absorb heat without increasing in temperature until it has absorbed enough for its phase to change.
There is an exception to this called superheating
What? People experience 100 f regularly. It’s literally their body temperature.
No it doesn’t, unfortunately.
What makes 0F (-18C) special? How do you estimate survivability at such temperature? If I’d be out on the street naked, I would die there in a matter of minutes. At the same time, there is plenty of places where winter temperatures go -40F (-40C) and even below, yet people very much survive and live there.
Similar with 100F (38C). There are places with higher temps in the summer, up to 120F (49C) in some places, yet people survive. Still, if you’re not equipped with anything, 100F (38C) will burn you alive.
All that not to mention that 50F (10C) is actually cold, not comfortable.
Fahrenheit is only intuitive and “feeling-descriptive” because you’re used to it. From a person born in Celsius country, it’s really not less intuitive. I know I can be comfortable in my birthday suit at around 25C. Less than 20 is chilly, less than 10 - cold, less than 0 - freezing. More than 30 is hot, more than 40 is deadly.
0F is the temperature a freezer needs to be to keep food fresh.
50F is the point that you can’t survive without clothes, your body will not generate enough heat.
100F (38C) will not burn you alive. You can survive for a long time in a sauna at 200F.
100F is perfect hot tub temperature
Freezer normally operates at -4F
You can’t survive without clothes at 55-60F, either.
100F will not burn you in an instant, but the comment went into long-term survival, and good luck surviving at that.
Not sure where you got -4F from.
USDA, United States Department of Agriculture, recommends 0°F or -17.8°C
100°F in the shade isn’t extreme, and you’d be able to survive normally (With more water, everyone can use more water)
100°F is hot tub water
120°F is recommended hot tap water
140°F water will pretty much burn you instantly
Guess what, Canada sets the freezer at -15 Celsius. The USDA just chose 0F because it’s good enough and a nice easy to remember number, there is nothing special about it.
Same with all your other numbers, your just using whatever the closest even F value is that’s easy to remember there’s nothing special about any of them and we have equivalents in Celsius
your freezer at -18 °C (0 °F) or lower. This will keep your food out of the temperature danger zone between 4 °C (40 °F) to 60 °C (140 °F) where bacteria can grow quickly.
According to Canada.ca
Every 2 F is basically 1 C. You have more whole numbers with F.
Like -15°C is 5°F
6°F is -14.4444°C
-14°C is 6.8°F
So 5, 6, and 7°F are about equal to -15, -14.5, and -14°C.
And it’s not just a random number. You know how much more energy would be used if everyone kept their freezer just a couple degrees colder? It’s the optimum recommended temperature.
The 120 and 140 don’t make that much sense unfortunately.
90-110 is hand washing temp. 100 average.
110 is hot
120 recommend max
130 very hot
140 very very hot
150 burns
If I said to you. Would you stick your hand in 50°C water for 100 dollars would you do it?
What about 60°C?
65°C?
I bet you don’t know what would happen if you stuck your hand in 65°C water without looking it up. There’s a huge jump from 60° to 65°C. 70°C will instantly scald you.
Someone out there is stupid enough to think. Water boils at 100°C, 65 should be perfectly fine. Even though water doesn’t boil until 212°, most people would be cautious of sticking their hand in 100°F+ water.
Yes if you think 40°C+ is hot then you can gather that 65°C would be hotter. But why compare to 40° when you can do 100°.
I wanna say that with this logic 50 should be right around the most comfortable temp… But for most people it’s closer to 70.
I’ll try to explain how easily mappable Celsius is to people as well.
-40 to +40… -40 being extremely cold, and +40 being extremely hot. 21c is the equivalent of 70f.
It’s all the same stuff. Just matters what you’re used to.
0-150 is the better range, and 75 is right in the middle. 100 is just a hot air temperature most people don’t want to be in but it’s not an extreme.
Saunas can get up to 200 degrees
Hot tubs are usually at 100
Freezers need to be at least 0
You say 15°C. 6° cooler than room temperature. But how much is 6°?
It’s 60°F.
50°F or 10°C is where you need clothes to survive
300, 325, 350 is where you bake cookies (149-176°C)
Fahrenheit has a bunch of 5 and 10s
Saying something like high 70s or low 70s for temp represents an easy way to tell temperature.
21° to 26° for celcius
I walk outside and say “It feels like high 70s today” someone using celcius would say, “Feels like 25°”. If it was a little warmer than “low 80s” compared to “Ehh about 26 or 27°C”
Why is it okay to say high 70s/low 80s and not high 20s? No one goes outside and says, “Ehh, it feels like 26.6 oC today.”, we just know it is a bit warmer than 25.
0-150 is the better range
Depends on where you live. Someone in Siberia would probably disagree, as the temperature there can reach -40
Yeah, I get your point. I think I’m just trying to explain that it all just matters where you grew up and what you used. I go outside today and I do say it feels like a 12 degree day. It’s not that much different.
I must admit, the oven temps are nice, but they are a product of being written in Fahrenheit (if they were written in celcius, it would be round too, like 150c, 160c, 170c, 175c, etc)
But the more I look at it the more I see it’s all just numbers. We put importance to these numbers but they’re all pretty arbitrary, except celcius using 0 as the freezing point for water and 100 as the boiling point- these are two very important measures that are just weird for Fahrenheit.
When do you use 0° and 100°C?
This is also at standard pressure and most do not live at sea level.
I don’t put a thermometer in my water to make sure it is boiling or one in my water to make sure it freezes.
It can snow and roads can ice before it hits 0°C
It has no real world applications
Both are equally arbitrary. You just have to know a handful of temperatures that you use in your day to day life either way.
Celsius being based on water makes it the most intuitive of the three imo.
Hum… Around here water boils at ~96°C (some labs measure that). And it seems to not freeze at 0°C anywhere on Earth, as it’s never pure water, with never an homogeneous freezing point.
It is repeatable, it’s not very arbitrary, but “intuitive” doesn’t apply in any way.
You must be at altitude. That definitely makes a difference for the boiling point, but of course water freezes at 0. Impurities that you’ll encounter in tap water, for example, will not have a large effect on freezing point.
Even if it was different by a few degrees, how does that make the scale any less intuitive?
Tell me that you are American without telling me you are American
There is absolutely no reason for Fahrenheit. It made sense before there was Celsius, but it doesn’t make sense today.
It’s better for weather and human reference. Fuck off with this tired rhetoric.
I’m curious, why do you think Farenheit is better for weather and human reference?
It’s a 0-100 scale of temperature relative to our senses and body temp. It’s also more precise.
And btw this is not just “why I think” Fahrenheit is better for these things, this is a widely understood consensus. It’s really only condescending elitist trolls on the internet that like to screech about fahrenheit because it lets them feel like they’re smarter than everyone else (this very thread being a fine example). Anyone who actually knows what they’re talking about knows there is no one single tool or reference that is best for all applications.
It’s only widely understood consensus in the USA. This would mean all countries not using Fahrenheit (so the most countries) are elitist.
I didn’t say “not using fahrenheit is elitist”.
I said “screeching and circlejerking on the internet about how fahrenheit sucks is the behavior of elitist trolls that just like to consider themselves superior to others.”
A person from a metric country complaining about fahrenheit because they don’t understand it is exactly as ignorant as a person from an imperial country complaining about metric.
Fortunately, in the U.S. we understand that both have their applications and use them accordingly.
You do not understand. The imperial system doesn’t have any use. You only see a use, because you grew up with it. It’s completely arbitrary and redundant. You can completely replace Fahrenheit with Celsius and you won’t miss anything.
Below 0 is freezing, 0-15 is cold, 15-20 is comfy, 20-25 is warm, 25-30 is hot, above 30 just stay out of the fucking sun, 100 your water is cooking. You see it’s easy to read how humans feel and as a bonus you don’t need to remember arbitrary numbers for relevant temperatures.
Wow either you’re trying really hard to not understand or you’re really just too thick to comprehend the information I’m giving you. Either way I’m not wasting my time on you anymore. You’ll understand when you have more experience in life.
Until then, enjoy your circlejerk, I guess.
Not really. This is more a matter of what you’re used to than “more tuned to the senses”. Which is nonsense.
It’s fine if you like it, but don’t make up junk reasons. Just own it.
“It’s fine if you like it, but don’t make up junk reasons. Just own it.”
Take your own advice. I’m the only one here that’s provided legitimate reasons as to why this is true, every other comment is basically just “lmao fuck Fahrenheit amirite?”
But honestly I’m really not surprised that a random meme community on the internet doesn’t understand an idea more complicated than “x good, y bad”. Believe it or not, science is more complex than that.
Oof, struck a nerve huh? You didn’t provide a concrete reason. You say it’s relative to our senses, but it isn’t any more than any other scale is.
Anyway, as I said, you can just like it cause you do. You don’t have to make up reasons for it.
Most heated post on Lemmy
No, your just used to Fahrenheit.
Celcius doesn’t care about your feelings
Converting from Fahrenheit to Celsius is quite easy. All you need to do is:
import math import random import time def obtain_temperature_scale(): temperature_scales = ["Fahrenheit", "Celsius", "Kelvin", "Rankine", "Réaumur", "Newton", "Delisle", "Rømer"] return random.choice(temperature_scales) def create_cryptic_prompts(): cryptic_prompts = [ "Unveil the hidden truth within the scorching embers.", "Decode the whispers of the arctic winds.", "Unravel the enigma of thermal equilibrium.", "Unlock the secrets of the thermometric realm." ] return random.choice(cryptic_prompts) def await_user_input(prompt): print(prompt) return float(input("Enter the temperature value: ")) def dramatic_pause(): print("Calculating...") time.sleep(random.uniform(1.5, 3.5)) def convert_to_celsius(fahrenheit): return (fahrenheit - 32) * (5/9) def main(): temperature_scale = obtain_temperature_scale() if temperature_scale == "Fahrenheit": cryptic_prompt = create_cryptic_prompts() fahrenheit_temp = await_user_input(cryptic_prompt) dramatic_pause() celsius_temp = convert_to_celsius(fahrenheit_temp) print(f"The temperature in Celsius is: {celsius_temp:.2f}°C") else: print("This program only accepts Fahrenheit temperatures.") if __name__ == "__main__": main()What you grew up with makes sense to you. Shock!
Kelvin is for scientists.
Celsius is for people.
Fahrenheit is a translation layer between Celsius and Americans. All their weather stations have been Celsius for ages, it’s a societal decision to use an arbitrary unit instead. The “69F censoring” which turned out to be a rounding artefact illustrated that nicely. Their government could change that, power to them that they decide not to 🤷♂️
fahrenheit is literally defined by celsius at this point, afaik celsius is literally the official standard of the united states but everyone just… keeps using fahrenheit anyways
There’s also no such thing as an inch. It’s defined by the meter, there isn’t an official yardstick.
The only reason the UK, Canada and USA used the same inch is because they needed to interchange parts for weapons and machines during WW1. Despite all thinking they used the same measurement system the definition had drifted between them. Metric was defined by enlightenment people with better methods of reproducing the standard. So it was easier to adopt a inch definition based on 25.4mm.
The UK and US inch only match because of WW1. The imperial volumes are still different.
Fuck Fahrenheit.
If fahrenheit was how people felt, then room temperature would be 0 because that’s the ideal temperature. Negative fahrenheit would be too cold, positive to warm.
I would like to use this system you propose. 0 is room temperature, plus/minus 100 is death by freezing or heatstroke… But we probably have to do some work to make units fit in a linear way. Are you filing the patent or am I?
Nah, it doesn’t make any sense, and isn’t deep or insightful at all.
Let me explain. Anything below 0F is really cold for a human, and anything above 100F is really hot. The Fahrenheit scale was built around human biology.
0C isn’t even that cold, and 100C is literally instant death. Thus, Celsius is less applicable to the human experience and more applicable to the physical properties of water. The typical range of human scale temperatures is like -10 to 40 degrees on the Celsius scale? Makes no sense.
Kelvin is the most scientifically objective scale, but also the least intuitive for humans, because absolute zero is completely outside our frame of reference.
So it’s easily demonstrable that Fahrenheit is how people feel, Celsius is how water feels, and Kelvin is how molecules feel.
Be forewarned that I am willing to die on this hill, and any challenges to my position will result in increasingly large walls of text until you have conceded the point 😤
main arguments from below
Celsius is adequate because it’s based on water, and all life on earth is also based on water, so it’s not totally out of our wheelhouse. But for humans specifically I think Fahrenheit is the clear answer.
One point that many may overlook is that most of us here are relatively smart and educated. There are a good number of people on this planet who just aren’t very good with numbers. Obviously a genius could easily adapt their mind to Kelvin or whatever.
You have to use negative numbers more frequently with Celsius > Celsius has a less intuitive frame of reference
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.
the intuition is learned and not natural.
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
Final edit: Well, I got what I asked for. I think I ended up making some pretty irrefutable points with these two last ones though. Once again, math saves the day. If somebody wants to continue the discussion make another thread and tag me because this is a bit much for science memes.
further arguments
It’s not about the specific numbers, but the range that they cover. It’s about the relation of the scale to our lived experience. Hypothetically, if you wanted to design a temperature scale around our species, you would assign the range of 0-100 to the range that would be the most frequently utilized, because those are the shortest numbers. It’s not an absolute range, but the middle of a bell curve which covers 95% of practical scenarios that people encounter. It doesn’t make any sense to start that range at some arbitrary value like 1000 or -18.
When the temperature starts to go above the human body temperature, most humans cannot survive in those environments. Thus, they would have little reason to describe such a temperature. Celsius wastes many double digit numbers between 40-100 that are rarely used. Instead, it forces you to use more negative numbers.
This winter, many days were in the 10s and 20s where I live. Using Celsius would have been marginally more inconvenient in those scenarios, which happen every winter. This is yet another benefit of Fahrenheit, it has a set of base 10 divisions that can be easily communicated, allowing for a convenient level of uncertainty when describing a temperature.
the end is nigh
Generally -40 to 40 are the extremes of livable areas.
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.
I would not mind if you were to expand
My argument is actually pretty simple, but people could always challenge these assertions, in which case it would get more complicated.
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. Celsius is adequate because it’s based on water, and all life on earth is also based on water, so it’s not totally out of our wheelhouse. But for humans specifically I think Fahrenheit is the clear answer.
One point that many may overlook is that most of us here are relatively smart and educated. There are a good number of people on this planet who just aren’t very good with numbers. Obviously a genius could easily adapt their mind to Kelvin or whatever.
But Fahrenheit is the temperature scale of the proletariat, the working man, the average Joe. And I’m here for it.
Multiple problems with you assertions.
A) Fahrenheit has an appropriate level of granularity for humans
You know that Celsius uses decimals for everything, so really not much difference. Furthermore the granularity of Fahrenheit doesn‘t have any advantages. You won‘t be able to feel wether its 70°F or 71°F outside, nor if you’ve got a fever of 101°F or 102°F. You need to look at a thermometer. And please don‘t reply saying that decimals are complicated. The majority of the planet, except certain Countries seem to manage just fine. Would be quite laughable if one certain country thinks it‘s too complicated.
B) Fahrenheit has an intuitive frame of reference for humans
Not really sure what you are referencing. I think it just stems from you growing up with Fahrenheit, so not feeling comfortable with anything else.
But Fahrenheit is the temperature scale of the proletariat, the working man, the average Joe. And I’m here for it.
I mean the “proletariat” of the majority of the world uses Celsius.
Honestly? I’ve only lived in countries with Celsius and Celsius is how I feel. I know exactly how hot or cold a day is gonna be if I look up the temperature. Thats how I know what clothes to wear!!! But Fahrenheit confuses the shit out of me. Every time I visit the US, I always convert the temp back to Celsius when someone tells me the temp.
I know Fahrenheit has more degrees and that can give you more datapoints. But cmon. The temp only goes up to, like, 50 C anyways lol. How many degrees do you need 🤣. Can you really differentiate between 61 and 62 F? Now, 60 to 65 F might be believable, but that’s like 15 to 18 C so, that much difference is shown even in Celsius.
I’m not saying Celsius is better, or that Americans should convert to it. Actually, if I was God-Emperor, I’d force us all to use Kelvin, given it begins with Absolute Zero and I’m a sucker for shit like that.
But variety is the spice of life. For Americans, Fahrenheit is how they feel. For most of the rest of us, it’s Celsius.
It’s more about the number range in ordinary use than the granularity.
Ordinary daily temperatures in F run from about 0-100. Numbers outside of this range are extreme weather.
Are people even capable of accurately perceiving a difference of 1 or 2 degrees in either system? I’m putting on a jacket if it’s 9 or 7 celcius outside anyway. Struggling to think of any human day to day situations where a difference of a degree or two changes the way most people act or feel.
If you need granularity, you can still get infinite granularity with decimals in either system.
the temperature also isn’t the only thing that matters, it also matters what the weather is like, how much moisture is in the air, and how windy it is.
With no wind you can have like -5°C and it’s perfectly fine if you just wear some fluffy clothing, but if the wind starts picking up it can be +5°C and you’ll feel like you’re going to die.
True, though this factor applies equally to both farenheit and celcius right?
19c, might be a bit too cold to wear shorts.
21c, shorts will be fine.
+15 for shorts, or +10 if doing sports
19 is too cold to wear shorts?
I’ll be back in an hour when i stop laughing.
Now that you have had a few minutes to laugh, please read my comment again, and notice that I wrote that 19c MIGHT be too cold to wear shorts, this obviously depends on other factors as well.
Boiling water feels really fucking hot which is why Celsius makes more sense
I doff my cap to those whose experiences have led to the statement “boiling water feels really fucking hot”.
Celsius can be used in place of all three, the others cannot.
The freezing point of water is also a great place to zero the scale.
The freezing point of water is also a great place to zero the scale
I disagree. Realistically the scale shouldn’t be able to be negative at all. It doesn’t really make any sense for something have a negative temperature.
Imagine if other scales worked that way. An object can’t be negative centimeters long. Light can’t be negative lumens. You can’t score negative % on a test. If you are measuring something you can’t have less than nothing.
It’s not nothing, it’s just below the freezing point of water. Zero energy is zero Kelvin. This is also a bad take because Fahrenheit also goes negative. I suppose you should just start using Kelvin if that is your opinion.
Who uses Fahrenheit in a first world country?
America bad!!
I don’t live there, so ill take your word for it.
yeah we know
No sense of humour eh? You need not reply.
