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 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.
Our bodies are mostly water why not use a system that reflects this?
The universe is mostly empty space with an average temperature of like... 4 Kelvin or some shit. Why not use a system that reflects that? Oh, we do? Right. Celsius is Kelvin + 273.15.
Are you made of mostly empty space? Your response does leave me questioning. Please aknowledge that you are made of 64% water and not 4°k nothing.
I mean, yeah, we all are. That's how atoms work.
alternatively, yeah, mostly between his ears.
As a matter of fact...
...rankine glowers in your general direction...
So then we should use the system that reflects the freezing point and boiling points of water at nice round values such as 0 and 100 then? Sounds like Celsius is the better system
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.
What is your point? That people who use Celsius can't feel the difference between 21.7°C and 22.8°C?
If you're worried about your thermometer, you'll be happy to hear that metric ones usually have finer precision than Fahrenheit ones, since they go in .5°C steps. Since +1°F means +5/9°C, you have less precision!
I would argue it's because of historical usage, familiarity, and resistance to change. Most countries and most people living in hot climates use Celsius.
Save yourself before it's too late.
Do not say anything positive about Fahrenheit in this thread.... the Temperature Scale Inquisition is watching closely for any dissent from the party line.
Fahrenheit is European.
*was
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?
Differences are neglegtable. 96°C is still going to kill you.
Not really, it's just the one you're more familiar with.
That certainly does play a role, but it also just makes more sense.
No it really doesn't. Knowing water freezes at 0 gives you no help in day to day life vs knowing 32 or 300 for water to freeze. You still have to be cautious driving above the freezing point. Your refrigerator sits a few degrees above 0 instead of 35 or 305.
Knowing it's 20 out only tells you useful information because you memorized what that feels like. You could just have internalized what 375 feels like.
Celsius is nice if you need to build a thermometer from scratch. That's not something people generally do.
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.
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.
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.
Depends on where you live. Someone in Siberia would probably disagree, as the temperature there can reach -40
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.
Good luck surviving in 0°F long term.
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
