I just use
30°C is hot, 20°C is nice 10°C is cold, 0°C is ice.
Obviously that won't apply everywhere, but in milder climates it works pretty good.
And 40°C is the melting point of the human brain.
Which goes some way towards explaining some of the decisions happening in Florida, Texas and Arizona during their ridiculously hot summers..
and 30C° is a typo
It's the best way to think about it because if you're always doing the calculation in your head you still always think in Fahrenheit first. Just get the feeling for Celcius instead of trying to shoehorn a worse system in (as a user of said worse system myself).
All those are still shorts weather.
And it's always helpful to remember that 40 below is 40 below, in both F and C.
(Whew, ninja edit so I don't look like an idiot, on Reddit I'd already have six people correcting me)
100°C is steam
Your reply didn't rhyme, try again next time. 😆
"30°C is hot" - laughs in Texan
Don't Texans just stay in air-conditioned buildings and vehicles all the time? I just saw a YouTube video where a guy in Texas was complaining that his air conditioning setup wouldn't get the temperature below 76°F, which I found odd since I set the thermostat on my AC to 26°C (which is nearly 79°F.)
Spot on
What's -10°C then?
For the other Americans that came into the thread hoping to see a conversion:
- 10c = 50f
- 30c = 86f
Edit: I'd like to note that 10c is a very reasonable temperature for shorts. I'm a Minnesotan (basically Canada lite (please annex us)), people start raising eyebrows at around 0C
F = C * 1.8 + 32
Just want to leave this here
Oh come on. Now you expect us to learn math too??
And if you want to do the math fast and just get close enough, you can just do “double it and add 30”.
its true, legs are immune to cold. shorts and a jacket is a reasonable outfit
0C? Fellow Minnesotan here and I've definitely seen plent of people wearing shorts at temps below -5C. But I'm also in a college town so that may change things.
I once amusedly watched girls sunbathe in bikinis at St. Lawrence University with patches of snow nearby in, I think March.
Conversely, I personally wore shorts and a tee one fine vacation in Florida around Christmas. It was 60f, and everybody was running around in jackets looking like they were in Chicago in January.
Lmao, that brings back memories of going to open gym in high school while wearing basketball shorts in -40 with my winter jacket on
The quick conversation I use is take off 30 and half the rest to go F to C or double it and add 30 to go C to F.
20C doubled is 40 and add 30. 70F
80F take off 30 is 50. Half that is 25. 25C
It's not completely accurate but close enough for conversation purposes.
I use that trick too! I just wanted to make sure I got it correct as a service
I learned during the polar vortices that when it's -40 out it's the same in both Celsius and Fahrenheit
Yeh 0C was exactly what I thought and then you mentioned it.
Paraphrasing an old meme:
Fahrenheit - how hot humans feel
Celsius - how hot water feels
Kelvin - how hot atoms feelWhat about Rankine?
Pretentious freedom-loving atoms
How measuring devices see it:
| Celsius | How hot humans feel | | Fahrenheit | Measure Celsius and do a calculation | | Kelvin | Measure Celsius and do a calculation |
Clearly, Celsius is superior here
C° or °C bud?
Jokes on you. I'm an american who works with scientific equipment so I mainly work in Celsius. Also live in Minnesota so we get the best of both worlds. Last winter hit almost -30C at times meanwhile tomorrow has a high of 39C with almost 70% humidity.
I was going to make the joke that Minnesotan kids definitely know what -40°C is.
I moved up here from Florida to get out of this kind of heat and humidity. Thanks Minnesota. This is miserable.
I love the annual tradition of people posting youtube videos in which someone throws a bucket of water and it instantly turns to snow.
It's going to hit 39 tomorrow? Gotdamn my wallet isn't going to like the upcoming electric bill
Yup. At least in my area. It's not going to be pretty. Hell I'm outside right now and it's over 30C at nearly midnight. I walked out the door and felt like I stepped into a sauna.
Americans know about °C, but what the hell is C°?
It's °C, but the temperature increases exponentially with every higher number
Oh shit.
Most kids don't get degrees.
Heyooo!
I prefer free health care units
Fuck it, it's 8 o'clock and 28°C with 60% already. We are not used to this shit here.
https://www.meteoblue.com/en/blog/article/show/40238_Heat+wave+in+Europe
Here's a rough C° primer for Americans
0° or below, fucking cold
1° - 10° cold
11° - 20° cool
21° - 30° warm
31° - 40° hot
41° or above - Jesus Christ I'm on fire!
As for Fahrenheit for the rest of the world, on a scale from 0 to 100, how hot is it? Assume anything below zero is really fucking cold, and anything above 100 is really fucking hot.
Yup. Where I live we have seen down to -20F (during that time texas almost lost their power grid) and up to 115F.
Its currently 110F. Aka, hot.
Or, -28c to 46C. Currently 43C. And 40% humidity. Feels horrible.
I was in Dubai earlier this year and the heat index was 53⁰C. Felt like I was being baked alive.
Why does the US live rent free in so many European's heads all the time?
Because each time we look for some English content, they use some dumb fantasy metrics based on the size fo the feet of a king for some reason, and we need to look up a converter to change it to a metric used in 195 different countries.
I measure in freedom units brother!
Also how did feet/metric get brought up, that's not even remotely relevant, tf lol.
I didn't know Canada and Australia were in Europe
I'd assume because the internet is 90% catered to american's.
I certainly know what degrees Celsius are, but I have no idea what Celsius degrees are supposed to be.
I thought that was the point Americans allegedly wouldn't understand. Glad I wasn't the only one that noticed the error in a meme trying to make another culture looks like idiots.
Annotation? Idk, I can't read as is
Kelvin gang
bursts into flames
I was taught both.
Just like I was taught both metric and imperial.
I use both temp scales, though fahrenheit is more common.
I use both measurements scales, though imperial is more common.
One thing I've never understood though. Metric is more precise for measurements (at least without needing to involve fractional measures). I totally get why it's superior for a lot of things, and indeed it is used in many places for this exact reason.
Why would anyone say Celsius is better? Apart from freezing and boiling temps seeming somewhat arbitrary with fahrenheit, does it not allow for much higher precision with regards to temperature identification without resorting to decimals? Isn't this the same rationale used with metric vs imperial? It seems like a double standard to me, because remembering two temperatures (for boiling and freezing) seems like a small price to pay for a more precise system.
I've always thought Fahrenheit was the better measurement in regards to weather. 0 F is uncomfortably cold, 100 F is uncomfortably hot. It makes so much sense for the weather. 0 C is freezing, 100 C you are dead. Of course, for most things Celsius makes more sense, and even though I live in the US I don't even know how to measure computer temperatures in F, it just sounds crazy. When it comes to weather though? Fahrenheit is where it is, in my opinion.
Please guys, I know plenty of you will disagree with me, that's okay, this is just my opinion. Please don't get upset I know metric is generally better!
I always found fahrenheit a lot more arbitrary: in Celsius 0 is the freezing of water, so if you are driving/walking, that is a very important temperature to look out for. Also 30 being hot or 100 being hot outside does not really make a difference. Some people find 30 hot, some other find it OK, since its subjective anyway
You are already using Celsius as well. If you just did not know Fahrenheit, you obviously would not miss it. To us Celcius feels just as natural as Fahrenheit does to you. It would be nice to have one global system we can agree on, just like we agree on english being the language of the internet. English is my 2nd language and if I can learn a whole other language, then americans can learn metric. (Is celcius part of the metric system? I have no idea tbh)
Because precision has nothing to do with it and it's all about being easy to convert between different units and having sensible zero and 100-points for temperature?
How often do you convert temperature to different units? Isn't that what we are stupid for doing?
And I would like to know why precision is irrelevant for temperature but relevant for other things.
I'm being genuine, I'm not trying to shit on you. I'm pretty open about liking the metric system, and I think the reason we don't use it is largely the extreme administrative costs of doing so more than anyone thinking imperial is actually better. I think most agree it's pretty clearly worse.
But I legitimately don't understand how people can argue Celsius over fahrenheit when the arguments for fahrenheit largely match those for the metric system.
Fahrenheit has a fairly sensible 0 - just as Celsius is the temp of ice water, Fahrenheit is the temp of salty ice water.
I pointed something similar with regard to thermometers to a group of European tourists. In Farenheidt, 98.6 is the normal temperature and if you are getting sick, people will say that 99 is a low-grade fever. While that is a. 4 degree difference in F, that's only a .2 difference in C.
Likewise for weather, F is much more precise and easier to communicate given that there is a smaller interval between units. There's more than 2 units difference in F for every 1 unit difference in C. That's huge when you're talking about the difference between 38 and 39 C
Celsius is better because it's the standard used by almost the entire world. If you're talking with anyone but Americans or you're working in science then you're using Celsius.
The rest is just arbitrary - you can get used to either system.
I don’t know if they stopped, but American kids at least used to be taught both Celsius and Fahrenheit. At least in some parts anyway. I was taught both as a kid, with my school largely banning the use of Fahrenheit by staff on campus even, for instance.
30 is hot 20 is nice 10 is cold 0 is ice
American here. Always knew C temps.
10 c cool 20 c perfect 30 c ok I need shade and a body of water 40 c wtf 50 c I’m dead
-5C your pee freezes when it hits the ground -25C you pee freezes internally -35C you pack the floofier sleeping bag for camping
-60C your hands freeze in minutes without very thick gloves.
Shorts in 10C is standard practice for me. Really not that cold for us in the NorthWest. Now if we're talking Southern Californians 10C is heavy winter jacket weather.
I mostly just wear long trousers in 10C weather in my current locale so as not to disturb the fine sensibilities of the local warmbloodeds.
Double Celsius and add 30. It'll get you close enough for environment temps.
10*2 is 20, plus 30 = 50.
(10°C × 9/5) + 32 = 50°F
30 doubled is 60, plus 30 is 90.
(30°C × 9/5) + 32 = 86°F
10°C is mild af. Who tf doesn't wear shorts when it's 50F?
If you want to sound more metal, tell people how cold it is in celsius. Was it kinda cold or was it in the negatives?
I find it easier to just remember the approximate table.
0C = 30F
10C = 50F
20C = 70F
30C = 90F
Me, an American, laughs in PC temperatures always being in C
10° C is warm lmao, where I live winter can get as cold as -34°C
Where I am in Aus we'd be lucky to see 0C once or twice a year at most in the middle of the night in the middle of winter for maybe an hour. I put on long pants or a sweater under 20C.
In the UK this summer we've been lucky if it hits 20°C this year. I've been in shorts all summer. We had a nice June but since then it's been cloudy and rainy. Regardless I've been in shorts since June. Winter is typically a single figure affair so summer is always very much welcomed. Feels like we haven't had one this year :(
Let's ignore the fact that celsius is taught in American schools because "hAha AMeRiCa bAd beCauSe nO MeTric."
Then why don't you USE IT?
I personally use metric as much as I can. The temperature on my phone for example is in celsius, try me.
Because for weather, °F is arguably better. 0°F - 100°F is the general range that most weather on the planet happens at (yes I know there are extremes where it gets to like -30°F or 120°F, but bear* with me). You can then further break those up into 10°F segments that are a bit more practical and granular than 10°C segments:
- under 0°F: stay inside
- 0°F - 10°F: really fucking cold, don't stay out too long or you risk hypothermia
- 10°F - 20°F: still really cold, but you can stay out long enough to shovel your driveway without fear of losing fingers/toes, if you're wearing winter gear
- 20°F - 30°F: cold but not bitterly so. Perfect weather for outdoor winter activities like sledding or snowball fights
- 30°F - 40°F: Snow starts melting here, and you can probably ditch the scarf, but you still need a winter jacket
- 40°F - 50°F: Too warm for your heavy winter jacket, to cold for your light spring jacket. It's layering season baybee
- 50°F - 60°F: still layering season, but you can probably get by with just a light jacket at this point, especially if you're doing something active outside. Some people start breaking out the shorts, but that's not the norm.
- 60°F - 70°F: a more generally acceptable range to start wearing shorts and short sleeves. Perfect temps for doing yard work and sipping beers on the patio alike
- 70°F - 80°F: definitely shorts weather, and pools start coming into play. If you're doing something rigorous outside, you're probably sweating
- 80°F - 90°F: you'd probably rather be inside, if you're not in a pool. You'll be sweating just lounging in your deck chair.
- 90°F - 100°F: hot as balls, probably not worth going outside for very long, as the pool water feels like taking a dip in lukewarm soup
- Over 100°F: stay inside
Now I know you can do something similar with °C, but the workable range there is smaller, because you're going from like -15°C to 40°C. It's less granular, and the start/stop temps are more awkward.
Is it weird that water freezes at 32°F and boils at 212°F? Sure, absolutely. When you're doing stuff in that context, it absolutely makes sense to use Celsius, where you're working on a nice, neat 0°C-100°C range. But weather, the thing most people contextualize temperatures with, doesn't happen in that range. It starts well below freezing, and (hopefully) doesn't get anywhere close to the boiling point of water. For that, I'd argue °F is actually a little more useful.
Because it doesn't have as much resolution as Fahrenheit.
There are 180 degrees between freezing water and boiling water in °F. But 100 degrees between the two in °C. So with Fahrenheit we can give mote accurate temperature info without resorting to decimal degrees. And if your response is "learn to handle decimals" then the same argument can be given for inches vs mm.
It’s taught but not really for weather. So while I know the boiling and freezing points of various substances in Celsius, I don’t have instant recognition when I hear a Celsius temperature, I have to convert it in my head.
Shit use of the meme bro
Okay but explain fractional inches and why this proves that the imperial system is flawed
Hey cool, we're like the Fire Nation
Just admit it, Celsius is garbage, use Kelvin cowards. Also this: Temperature scales
Kelvin use the same scale as Celsius, the only difference is the zero point. The imperial system and Farenheit sucks and result very expensive and cause even deaths because of wrong conversions: Crushed 2 Mars probes >$350M, flight crash with more than 130 victims because of an error calculating the amount of fuel, wrong amount of medicine respect bodyweight, etc..

vs
The US doesn't use imperial, it uses US customary.
There's no US customary Roman mile, ell or skeine, for example.
Chains and links are basically standard surveyors chains. They're distinct units in their own right in the sense that a metric chain or metric link is. Should your metric chart have a metric chain on it? What about light years or parsecs?
Hands are used in measuring horses, and that's basically it. They're used in commonwealth countries, the US and South Africa.
Irc the US is now the only (or one of two countries) that doesn't officially use the metric system. Uncle Sam just needs to rip the bandaid off.
Metric is Fer socialistcommies...now let me chug this 2L coke!
Fuk yeah brother! God Bless the Double Large Coke freedom unit! /S
Except they do use the metric system, all their imperial units are defined by metric units.
That is at least a better basis than the barleycorn.
I don't understand the meme and I use C...
The C is the grade those kids on got in "Temperature Understanding Class" because they're almost failing.
An American: lmao. Seriously? Y’all weak. No shirt & Mohawk/Mullet all day! Lol just messing around
Not just us not understanding Celcius. Where I come from, we wear shorts down to 0°C or lower.
Seriously, my first reaction was "10C isn't even that cold."
Multiply by 2 and add 30
Specifically it is: (c(9/5) )+32=f
It actually depends on humidity and movement of wind as well as tempreture
Not gonna lie, this is my experience.
At least I try. I have the gist of it, and agree it's a more sane scale. I know 40 is around 100f, for example.
American kids wear hoodies in 30C+ for some bizarre reason.
I can understand canadians wearing shorts on a 10° day, Aussies sometimes do the same. But what Australian wears a jacket on a 30°C day???
As a Canadian who spent a few years of my youth in Australia: I can definitely confirm.
I spent most of my ozzy summers in a black hoodie for some god forsaken reason, and I also wear shorts in winter occasionally....
I always wear shorts. 50f/10c isnt gonna stop me.
Americans do understand Celsius, although it is unfortunately not as commonly used for weather/room temperature as Fahrenheit
Not all of us do. Source: me
The easy but not quite right conversion from C to F is to double it, then add 30.
F to C is subtract 30 and divide by 2.
I've always learned 32, not 30
When doing a simple double/half, 30 will give less average error between 0° and 100°C. Though the real formula is C * 9 / 5 + 32 = F
Unpopular opinion time; the US already uses metric/Celsius where it matters; in science, engineering and the military. Where it doesn't matter, we use a weird hybrid system that makes intuitive sense to us and is accordingly perfectly functional and doesn't need to be changed.
Is it weird that I use C for negative and F for positive? lol
Is 31° positive or negative?
That is honestly a good question lol
They’re both made up numbers by humans 🤷
the fact that 20-30 points goes from freezing cold to death and destruction and fire is everything that's wrong with Celsius for weather.
F for weather C for chemistry K for astronomy
FCK one unit of measure.
Why is that a problem once you know it? I know 0 is kinda cold, 20 is kind warm and 30 is kinda hot.
45 is shit
Loss of precision. Most digital thermostats only display two digits for cost savings. I've had experiences with mini-splits that are too cold at 27 and too hot at 28.
Mate, it's metric, if you need more units just go down an order and you have 200 to 300 units.
In Celsius we at least have some leeway to adapt to the rising temperature of the Climate.
talk about your silver lining! Hey, we never really got to use 50 deg C in weather yet! Hype!
Farhenhiet and Celsius are equally made up. All measurement systems that we use on human scales are made up. And in this case, farhenhiet is actually just better. More granular and more useful on a day to day basis. Yeah, it doesn't have the freezing point of an arbitrary substance as the 0, nor the boiling point of an arbitrary substance at 100, but it has temperature you should immediately be concerned about coming into contact with outside of -20 and 120, temperatures you should be concerned about contacting outside of 10 and 90, and fairly normal weather between those two.
I don't care too much about 100 being the boiling point of water, but 0 being the freezing point is really convenient. Most weather has something to do with water, negative temperatures mean snow and ice.
Fahrenheit: 0=cold, 50=mild, 100=hot
Celsius: 0=moderately cold, 50=dangerously hot, 100=deadIt makes no difference to me if the boiling point of water is 100°C or 212°F, if I see it boiling the pasta goes in.
In a scientific context Celsius and metric in general are superior without a doubt. But to live my life Fahrenheit works just fine.
The only important property of a temperature scale is that it exists and is agreed upon for science. Farhenhiet and Celsius do that job equally as well.
Stupid. I hate these "America dumb tehehe" memes.
They seem to be mostly loved by left of center Americans that enjoy stereotyping their fellow countrymen by saying "Merica" a lot. 🙄
Imagine disliking a meme and somehow bringing in politics into this. Go touch grass lol
In the rest of the world, we call left of center Americans "normal people"
You mean "in Western Europe."
If your country dose a lot of stupid shit people will make memes about it, you dumb American!
The US is a cultural hegemon so it is often picked on. There are tons of idiotic peoole and cultural practices here in Spain. But the rest of the world isn't really aware... I mean I don't blame them. One cannot keep up with everything.
But believe me, stupidity and insular thinking is just as endemic here as it is in the States. It just annoys me when "enlightened" Americans habitually paint other Americans as somehow dumber than dumb people elsewhere.
