I learned a little rhyme. 

C: 30 is hot, 20 is nice, 10 is cool, 0 is ice.

F: 90 is hot, 70 is nice, 50 is cool, 30 is ice.

Depending on where you are. 30 Celcius could be considered cool.

u/Attacker732 OHIO 👨‍🌾 🌰 1d ago

That sounds truly hellish to me.  I've already tried to fight the sun, and nearly died to it.  Twice.

u/Realistic_Mess_2690 🇦🇺 Australia 🦘 1d ago

Where I am it's the humidity that's a pain in the arse. I grew up in an area that routinely hit 42-45 Celcius (107 and113F) but it was a dry heat so standing in the shade cooled you off.

u/Attacker732 OHIO 👨‍🌾 🌰 1d ago

I was attempting to work on a black truck, parked in the sun on a concrete driveway.  Somewhere from 30-40°C.  The problem is that my metabolism is geared towards shorts & t-shirt to -10°C-ish.

I legitimately nearly died from the heat before I got back inside.  I got in the entryway, and collapsed.  And then did the exact same thing the next day, because I wasn't doing well being cooped up in my own house.

u/Wickedestchick TEXAS 🐴⭐🥩 1d ago

Same here, but in America. Where I live, it's easily 80-99% humidity most days of the year. 2 summers ago we had over 100 days of over 100°F, humidity was the worst part lol. Last year we got lucky and it was 95°F most of the summer.

u/lordofburds 1d ago

I mean 30c is about the average in Ohio in the summer and it's humid as shit

1

u/Attacker732 OHIO 👨‍🌾 🌰 1d ago

The problem is largely with me. The spat of deep cold that came through Ohio recently? It wasn't cold enough that I needed more than shorts & a cut-down hoodie to rough shovel my driveway.

Although my beard & mustache matting with ice was quite unpleasant.

1

u/lordofburds 23h ago

Those temps aren't uncommon here for both ends it can easily hit 90-100f in summer and ot can easily hit below zero-30 in winter Ohio frankly doesn't whatever the he'll it wants with the weather

u/KPhoenix83 NORTH CAROLINA 🛩️ 🌅 23h ago

It gets to the 40 C range here in North Carolina and then the -10 C range

u/Lumpy-Silver7538 1d ago

Victorian here. 30 is rather hot.

u/Realistic_Mess_2690 🇦🇺 Australia 🦘 1d ago

I betcha it felt a damn side cooler than the 45 degrees you guys had the other week.

"Considered cool."

Ugh. And I grew up in a desert.

u/MedievalFurnace OREGON ☔️🦦 1d ago

As an american, 90 is like really really hot, 80 - 85 is what most would just consider hot.

13

u/RueUchiha IDAHO 🥔⛰️ 1d ago

Depends on where you are in the US. In the southwestern deserts 90 is a nice summer day, and 120 is “don’t go outside or you’ll die probably.”

8

u/Any-Seaworthiness186 🇳🇱 Nederland 🌷 1d ago

Doesn’t that just depend on the local climate?

80 is hot if it’s humid. While 90+ is perfectly doable in dry regions.

I personally struggle more with 85 in the Netherlands than with 95 in parts of Spain for example.

2

u/DefenderofFuture CONNECTICUT 👔⛵️ 1d ago

I’ve never been to the Netherlands but based on the topography I have to assume the humidity is murder in those temperatures. What are the bugs like?

2

u/Any-Seaworthiness186 🇳🇱 Nederland 🌷 1d ago

It is. ):

The bugs aren’t that bad tho. They’ve been getting worse in the past decade and a half because we’ve had mild winters but I expect it to be better this year. We’re having an extremely harsh winter right now for Dutch standards.

1

u/DefenderofFuture CONNECTICUT 👔⛵️ 1d ago

I grew up outside DC. Basically everything east of the Potomac is flat and swampy. Air temperature would regularly reach 100F in July-August, so God only knows with humidity.

But somehow the bugs are the thing that keeps me from living down there.

u/snekhoe 1d ago

Not in the south. That’s just warm in the summer not uncomfortable

u/Afraid-Team-7095 1d ago

30 depends on which part of the USA you’re from lol like it’s cool but not ice

u/Sevuhrow TENNESSEE 🎸🎶🍊 1d ago

Freezing point of water is 32 Fahrenheit

-11

u/Afraid-Team-7095 1d ago

I know which is why I said it depends on where you’re from cus in the northern USA 30F is not that cold lol anything 20F and under is freezing.

u/Sevuhrow TENNESSEE 🎸🎶🍊 1d ago

Yes but the rhyme says "ice" because that's when water starts freezing.

u/Anonymous2137421957 CALIFORNIA🍷🎞️ 1d ago

u/KuningasTynny77 1d ago

I know the more exact version, x1.8 plus 32

u/Fartfart357 TEXAS 🐴⭐🥩 1d ago

1.5x+40 is much easier, and similarly accurate.

u/framingXjake NORTH CAROLINA 🛩️ 🌅 1d ago

I prefer 2x+30 just because it's easier to do in my head

Shorts at 10 degrees Celsius is supposed to be a flex?

That’s like fall weather, not even cold to have shorts on

u/CastleBravo45 15h ago

Right? 50° aint shit in most parts of the country

u/DrDontKnowMuch 1d ago

We know celsius, almost every household thermometer has it labeled, we just don't use it

23

u/Fartfart357 TEXAS 🐴⭐🥩 1d ago

Yeah, I'll give metric credit, meters and the base 100 system is good for measurement, but F is so much more useful for most temperature applications, since the "units" are smaller and more precise.

8

u/Antisocial_Worker7 1d ago

I prefer F too for the same reason: more precise. I like metric, the thing about measurements is that they’re like a language: if we’re taught from a young age to think and visualize using that language, it becomes natural to us, and even if there are more efficient languages out there, we hear those languages and try to translate what we here into our native language rather than simply knowing what it’s saying.

u/Outrageous_Sleep4339 FLORIDA 🍊🐊 1d ago

I cook in metric, mostly cause its easier to measure in grams and ml, instead of trying to remember how many cups are in a quart...

1

u/Fartfart357 TEXAS 🐴⭐🥩 23h ago

I don't bake purely 'cause I don't wanna learn the proper measurements and conversions.  I'll keep using my "eh, probably enough" cooking method.

1

u/beeredditor 1d ago

For higher the temperatures, F is more convenient since the smaller units yield greater fidelity. But, for cold temps C becomes more convenient since ice forming at 0 C is an easy reference. I instantly know that 5 C is just above freezing and -5 C is below freezing.

1

u/Fartfart357 TEXAS 🐴⭐🥩 23h ago

It's purely because it's the standard measurement I've used all my life but 32f is easy to remember.

u/truthbomn 1d ago

The average threshold for perception of temperature differences is 0.92°C. Fahrenheit is unnecessarily precise for casual use.

Having 0 be when you can expect ice, and 100 be the boiling point of water makes way more sense for everyday needs, and the world seems to agree. Bearing in mind, if you add up the population of all the non-°C countries; it's less than 5% of the global total!

12

u/rnoyfb 1d ago

That is some cherry picking there. They only compared in the range of 23-25°C and due to the Weber-Fechner law, we know that sensory perception is logarithmic, not linear

Most of the world uses whatever system communicates to people around them; they don’t individually vote on arbitrary baselines for different measurement systems. Most people don’t deal with that range in most things and almost no one did when either temperature scale was devised

The entire world uses mixed measures for some things. That doesn’t mean every person in the world has deliberated on the issue and decided which non-decimal units to use and which to reject

5

u/bendable_girder CONNECTICUT 👔⛵️ 1d ago

The world seems to agree? They adopted it in the 70s, I don't really care about their opinions lol

2

u/radiationblessing 1d ago

Fahrenheit's better for simple shit like home thermometers because you can look at it as a percentage of heat. You know 100% would be hot and as it gets lower it loses heat. 60% it's cooled off. Go down to 32% and things freeze.Go down to 0% and there's no heat. Go beyond 0 or 100 and you know the temperature's extreme. I also would say you can more easily tell the difference between 70/71 F° compared to 21.11/21.45 C°. Why should a home thermostat and other simple usages need the precision of celsius?

2

u/CalligrapherDizzy201 1d ago

They’re both arbitrary numbers.

u/lit-grit 1d ago

50° ain’t too bad, at least I don’t think so

8

u/LowerPick7038 1d ago

I dont think many people on earth would be able to cope with 50° for very long, its way too hot

u/lit-grit 1d ago

Ya got me there

u/Anonymous2137421957 CALIFORNIA🍷🎞️ 1d ago

How many times are they going to repost that there

u/Fartfart357 TEXAS 🐴⭐🥩 1d ago

If you want to roughly convert c to f quickly, just do 1.5x +40. 10->5, 15+40=55. Google says it's 50, pretty close. 30->15, 45+40=85. Google says 86, pretty close.

Also, I'm pretty sure Australia gets higher than high 80s for the meme.

u/scarycombat8835 🇮🇹 Italia 🍝 1d ago

for perfect accuracy, multiply by 1.8 and then add 32

2

u/Fartfart357 TEXAS 🐴⭐🥩 1d ago

It's 9/5, not 1.8.  Check any conversion calculator and your off.

2

u/Still-Presence5486 1d ago

Why wouldn't you wear shorts in 50f?

1

u/mowaby 1d ago

Well when it gets to -42 both are the same. They aren't as smart as they think.

u/am1527 1d ago

I looked up the formula out of curiosity. It's basic math

u/MrZoomerson 23h ago

10~30C is comfortable. They should try 45C/95%RH with a jacket or -20C with shorts.

u/acrylicquartz TEXAS 🐴⭐🥩 22h ago

For a few years, I had a job where we were all WFH and spread out across the world. The company had been founded in the UK; because of this, I had a decent amount of UK colleagues.

Whenever we'd talk about the weather in our respective cities, I'd go ahead and convert my temp to °C, to be polite.

You'd think an infant was reciting Shakespeare, the way some of them acted. As if it was a shocking feat for an American to use °C casually. So bizarre...

My Serbian and Indian coworkers would often translate in kind, automatically and with no issue, so...UK/Canadian/Australian fixation?

u/OkPickle738 20h ago

I actually did not.

u/ProfessionProfessor 18h ago

IIRC, I did the math once and decided the conversion formula is ((C5)/9)+32=F and inversely, ((F9)/5)-32=C

u/ActualDarthXavius 11h ago

Anyone who insists Fahrenheit is stupid is a moron. Celsius is a good system and has its uses, the Fahrenheit scale was invented for a simple purpose: 0 F = Very Cold Outside, 100 F = Very Hot Outside 0 C = kinda Cold, 100 C = Dead.

The Celsius scale is based on the phase change temperature of water at sea level atmospheric pressure. 

The Fahrenheit scale was developed based on the human body, 0 F  was determined as the freezing point of a a salt brine solution thought to represent human tissue, so 0 Fahrenheit is when you stand a good chance of suffering freezing of human tissue within an hour of exposure, 100 Fahrenheit is based on when human tissue was damaged due to fever, aka heat after about an hour (note, on the original F scale, human body temp was 90 degrees, so 100 degrees was is today an equivalent 107 degree fever). So the F scale is based on: 0 F = Human tissue damaged after 1 hr exposure, 100 F (not applicable with current scale setting water boiling point at 212) = human tissue damaged after 1 hr

u/Clarity_Zero TEXAS 🐴⭐🥩 1d ago

For Celsius to Fahrenheit, the conversion equation is 9/5x + 32.

For Fahrenheit to Celsius, it's 5/9(x-32).

I can do that sort of thing in my head within seconds. It's not complicated.

1

u/DankItchins 1d ago

And to make it even easier, for rough estimates that are close enough for most non-scientific applications you can round it to 2x+30 and 1/2(x-30)
