5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials or celebrity gossip is allowed. All posts will be judged on a case-by-case basis.
7. No duplicate posts.
If a source you used was already posted by someone else, the autoMod will leave a message. Please remove your post if the autoMod is correct. If the post that matches your post is very old, we refer you to rule 5.

I get your point, but disagree with your thesis. Fahrenheit makes a lot of sense for human comfort ranges. 0 and 100 are some of the most extreme natural temperatures most people in F-using countries ever see. 0 means cold as fuck and 100 means hot as fuck. And there’s a single-digit useful precision to it as well. 72 and 73 are close, but noticeably different. Celsius requires decimals for that kind of difference. And 0 means “it’s kinda cold outside, I guess” and 100 means “you were dead a long time ago”, so it’s not nearly as useful in every day life with natural living temperatures.
So you're saying it's relevant for basically nothing but the weather. It's not a very good argument.
To be fair, that's all it's used for. No one uses Fahrenheit for science in the US.
Is also incredibly subjective. What's comfortable for one person might not be for another. I'm pretty sure an Inuit and a Ghanan have pretty different ideas of what's cold or hot. Same for Floridan and Minnesotan speaking of the US
0 and 100 are not comfortable for anyone.
I get your point "but because I was brought up with this system I'm going to make an argument as why it makes sense to me"
25 Celsius is a nice summer day
0 Celsius you better take a jacket and it's probably going to snow
43 Celsius damn hot
60-80 Celsius a very nice sauna
It's not that hard burgerman
Hey, we didn't come up with the shit in the first place. The Imperial System is a British invention.
Once upon a time I was going trough some hardships, sometimes I couldn't afford a meal, I'm not proud to admit that one time I took paper towels, wet them in a bowl and eat them, and you know what? Still had more flavor than br**ish food.
If it requires this much explanation, it's not very sensible.
In Celsius 0 is freezing and 100 is boiling. It's so simple. "Comfortable" is anywhere from like 15-30 (my Canadian standards, very subjective I know) and we don't need decimals.
Here you go. Pretty simply, really.
"Fairly cold"? I've been in 0c a few times in my life and every time it was freezing!
Isn't 100f the temperature your blood is meant to be?
98.6°F is body temperature. The .6 is funny because it's only there because someone picked a nice round number in °C then converted it. There's a name for that in math but I can't remember what it is... something about more precise than accurate...
It's honestly really intuitive for weather if you grew up with it. We still use metric for science because it makes the most sense there, like you say.
But it's not that simple. 100 boiling is only true at sea level. At 530 (~1750 feet) it's 98c. At 1500m (~5000ft) it's down to 95c. At 3000m (10k feet) it's just under 90c. Ocean water freezes at -2c. Fully saturated salt water freezes at -21c.
Fahrenheit doesn't have this issue?
Fahrenheit and Celsius both have the exact same issues. Which is why there isn't much reason to switch.
Temperatures can be given more accurately in Fahrenheit with whole numbers
That's an approximation. Celsius is no longer defined in terms of water boiling and freezing, and they are no longer exactly 0 and 100.
The modern definition of Celsius is based on absolute zero and the triple point of water. And those are also the basis for the modern definition of Fahrenheit.
Any usefulness of Fahrenheit is purely accidental, how is water freezing at 32F useful? I'll grant that the finer resolution can be seen as a positive, I don't see how Fahrenheit is better for human comfort, my personal optimal comfort zone is 22-24C°, and I have no need for decimals for that. 73F is pretty close to 23C, I don't see much difference regarding comfort in either.
The huge problem with Fahrenheit, is that it is impractical in many situations, it has basically no merit to justify its existence, and only a minority of countries continue to use it.
Of course Americans can do whatever they want, but they are looking stupider for each year they keep using "Freedom Units".
Of course Americans switch to metric for mostly anything scientific, for example NASA use Metric.
The usefulness of gravity is also purely accidental
False equivalence. gravity is not man made.
The SI unit of temperature is kelvin, not Celsius.
If people don't want to use kelvin, does that mean they are stupid?
True, but Kelvin is based on Celsius, only difference is that zero is moved from freezing water to absolute zero. Celsius however is more practical for everyday life.
Celsius is only practical if you measure the temperature of water more often than the temperature of air.
But most people never measure the temperature of water, and frequently measure the temperature of air. For them, Celsius offers no advantage.
Why? As I see it, it's quite practical for air too, epecially when considering humidity.
A scale that typically goes from -20 to 40 is less practical than a scale that typically goes from 0 to 100.
Humidity is irrelevant. Celsius is useful only when measuring the liquid phase of water.
0 means any water outside will most likely start freezing, 100 means any water outside will be boiling. Makes sense to me. What temp do things start freezing in F? 30? 40? Doesn't make sense at all. What temp does water boil? 160? I dunno, none of it is rational in any way.
0/32/64/96 are somewhat reasonable breakpoints in F, and make dividing the space between them in half repeatedly on a thermometer simple. Fahrenheit was literally made up by Big Thermometer for this exact reason.
"Somewhat reasonable"
Lol, big thermometer.
they are all arbitrary numbers. Originally C actually had water freeze at 0 and boil at -100
Salt water freezes at 0F. Normal water at 32 F. Normal water boils at 212 F. Human body at 100 F (which is wrong, but also has been changing.) Below 10 F snot in nose freezes. 20 F is time to switch to long pants.
Water freezes at an obvious 32°F at sea level and of course boils at 212°F. What's so confusing about that? /s
Water boils at 99.9839 Celsius, not 100. What so confusing about that?
Hi sepo, :)
I get your point
