you've got me, I don't know what C° is, I only know °C
post
FYI this is like 283 and 303 kelvin
What is that in Rankine?
Heatwaves in London are strange. You see a few people outside in light sweaters. It's like they don't know what to do. It's like they don't own t-shirts
I always wear long sleeved shirts, because I burn very quickly and don't want skin cancer and I really dislike applying sunscreen all the time.
But a heat wave in London is, what? 25 degrees?
Last big heatwave hit 35 here and I'm only an hour and a bit away from the edge of London
unfortunately it did go over 30° the last time i was there. but tbf also that's the hottest it gets

40C in London in 2022,
37.7C last month (June 2026)
https://www.metoffice.gov.uk/blog/2026/june-2026-heatwave-a-recap-of-the-temperature-records (for avoidance of confusion those are the records for June - the 40C was July 2022)
Anything over 28C is currently classified as a heatwave, but I think they're going to have to revisit that, or just say "all summer is a heatwave try not to die" given 32-35C has been consistently hit pretty much every summer this decade.
That's only 86F. It's not a heat wave in the US until it's in the mid 90s. That's 35 Celsius.

That 111 you see is 43.9C.

yeah it's not bad globally, but it is pretty bad for london, the infrastructure isn't prepared for it
esp because it's pretty humid as well, sweating doesn't do much
Yeah, the humidity also doesn't compare. The US is, as with most things especially lately, way worse.
None of this means the UK has it easy, don't misunderstand. It means the people stuck in the US are in a crazy land of stupid things which includes the weather. But at least there aren't Australian murder fauna I guess.
62% humidity outside right now, 99° F "real feel", 92° F "real feel shade". 88° F actual temp.
I think what folks from not humid places don't realize is how hot the shade is. Shade is always better than sun, obviously, but it sort of only takes the feeling of the sun against your skin. The air is still hot. I'd compare it to a sauna sort of. Like it's still stuffy.
The first time my wife went to somewhere that actually has dry heat she said it was amazing. She was actually cold in the shade. Not just cool. That concept is so foreign to me.
Jackets at 30C??
An Australian family moved to my town on some kind of exchange and yah, the one kid was still wearing a jacket at 30. Literally never wasn't cold.
Taught us how to play cricket, he was a cool kid.
as someone who has visited one of the hottest countries on Earth, yeah... 30C in countries like that, is considered chilly. There were a couple of days in a row where the temp reached 50 and kept crawling. My Scandinavian ass was not ready.
"When will I ever use this in real life?!?" I wonder how successful "to understand the international memes" would be in the classroom 🤔
Yeah but, 10c is 50f, which is not cold for shorts. Maybe cool at best? I wear shorts year round though 😬.
That entirely depends on where you live and what temperatures you're used too. I live in a hot part of Australia and absolutely wouldn't wear shorts in 10c because my body is acclimated to hotter weather.
In Canada 10C is warm.
Are you a 'shorts every day' guy?
Australians totally wear shorts all the way down to 0 degrees.
Kiwis too, on the south island while wearing jandals in June.
There's a lot of jackets in November with 20° weather, at least in Melbourne - I got so many chuffed looks for wearing a T-shirt in cloudy weather
if you been in stem in the US, you would use metric. people get wierd when you say kg, instead of lbs, or m/KM instead of miles.
Just use Clicks. Then people will thank you for your service.
I never understood why the US military is so frightened of syllables.
For those who don’t know the quick and dirty conversion it’s double it and add 30. So both temps are ~50F and ~90F
Less quick and dirty is double it, take off 10% and add 32. So both temperatures are exactly 50°F and 86°F
It's close, but I just used this to convert my local temp from F to C and it's off by 2°, which is huge for Celsius...
Come to New Zealand, we wear shorts (or stubbies as they are known over here) all year round!
its cold in New Zeeland?
I don't really get the hate for fahrenheit. It's a nice 0 to 100 scale for everyday weather temperatures. But also every 10 degrees is different enough that you don't even need to be precise when talking about it: "We'll probably need the AC today, it's going to be in the 80s".
I'm an American that's all for converting to metric but I would still use fahrenheit for weather since it's just so easy and convenient.
You do realize that we're not ignorant to the metric system, right? Anyone with even the slightest interest in science and/or computing knows what celsius is.
I know neither one is freezing. Or boiling, because my coffee brews at 95° C, max.
I suppose posting this meme with F instead of C would confuse more of the world than this one will. When trolling its all about numbers people.
I understand because of a useful mnemonic I learned a few years ago. 30 is hot. 20 is nice. 10 is cold. 0 is ice. 30 is still pretty nice for most US citizens since we're not Canadian.
Ah, you see it’s easy! 10°C is 70°F in Canada and 30°C is 35°F in Australia. Fahrenheit is based upon comfortable temperature and since that differs by person and population the amount differs too!
Celsius is just boring old math though. Kind of like metric measurements. Everything devisable by 1000? Pffft, boooring! Give me my 600 feet to the mile and 8-1/2 football fields to league like a truely patriotic measuring system! Did I mention I actually prefer needing a lookup table to figure out unit conversions.
Im one of the few people in America that uses C unironically
Does everyone ask you "whats that in Fahrenheit"?
Do you also say random words in foreign languages and then explain that "ライブラリー" means "biblioteca"?
No but sometimes but my vocabulary randomly and sometimes for no reason at all contains some words that British ppl use and sometimes Australian :3
(Although its extremely tempting to learn German just so I can randomly start speaking in German)
You are one of the good ones..
Of course I do, it stands for Percentage of Commie.
These poor folks don't even know in a free country you can wear jackets and shorts any time you like.
Wait. So is it a flex to wear shorts at 10? Is a jacket at 30? I'm so confused. That's like the mildest of temps. How about when we do yard work when it's 37.5c? Or go kayaking in 7c because like all those things happened are normal here. I was building a fire pit area today and it was 100° and earlier in the year I was on the lake kayaking when it was 45°.
I wear black jeans and black tshirt in the height of summer cuz aesthetic beats comfort any day
Never seen a C in my life
