European here! For me it's...

Celcius:

0 = Water freezes

100 = Water boils

Fahrenheit as far as I can tell:

~100 = Hot enough that it shows up on the news

~400-450 = Cooking, because our stove is in Fahrenheit for some unknown reason.

All other temperatures in F = no idea.

You can think of F as a “% hot” measurement for weather.

0 = no heat: getting dangerously cold for humans. 50 = half hot, half cold: wear long pants and a jacket. 75 = three quarters hot, getting close to t shirt weather. 100= fully hot: getting dangerous for humans.

Yes you can go over or under, but you can consider those to be extreme weather (120% hot!)

C is a measurement for water.

75 is only close to tshirt weather?

[–] [email protected] 21 points 1 year ago* (last edited 1 year ago) (3 children)

Acclimatization is a whole thing. I remember thinking 65F / 18C was cold once upon a time, then I moved north and now only bother putting on a jacket if it's below 40F / 5C or so (but now I start seriously suffering above 85F / 30 C where that used to be my ideal temp).

People who pretend certain temps are objectively not that cold or hot have never moved from one climate to another, I think. The person you replied to must be from a hot area.

I spent a week in the Rockies and when I got home, my house at 24°C was just too damn hot I just drank ice water and sat in my underwear.

[–] [email protected] 3 points 1 year ago

Yep. I lived in the middle East and SE Asia combined for around 12 years, and while occasionally it was too much, in general I loved the heat and rarely said "its too hot", I moved back to the UK 3 years ago, in June. Hated it, was cold all the time. Now when it's more than 25c / 77F on a calm and clear day I'm boiling and can't sleep at night (barely anyone in the UK has ac at home).

[–] [email protected] 2 points 1 year ago (1 children)

But what can you do if your area climate includes 110+ F summers and below 0 winters? Besides moving, that is.

[–] [email protected] 1 points 1 year ago

Live in a climate controlled building. Or just die, probably.

[–] [email protected] 3 points 1 year ago

It really depends on what your body is acclimated to. When I lived in Texas it felt a little too cool to be t-shirt weather. Now that I've been living in Seattle for years, it's safely within the realm of t-shirt weather.

[–] [email protected] 1 points 1 year ago

70 it hoody and jacket weather for me, so yeah.

[–] [email protected] 15 points 1 year ago

Fahrenheit is designed for humans. Celsius is in love with distilled water at sea level. Kelvin and Rankine are actually useful in math, science, and engineering.

My wife told me to go look at the thermometer outside and the needle was pointing to 0. She asked "what temperature is it?" I said, "uh.. there isn't one."

[–] [email protected] 5 points 1 year ago (1 children)

0 = no heat

Kelvin and Rankine would like a word.

[–] [email protected] 1 points 1 year ago

They aren’t scaled properly for weather temperature.

[–] [email protected] 5 points 1 year ago

This is pretty good! I'll keep this in mind next time I'm in the US.

[–] [email protected] 0 points 1 year ago (1 children)

Sorry but that makes no sense to me.

Is 0% hot no extra heat, like perfect room temp or is it zero heat, the death of all life?

What does 100% hot mean?

You arranged it for yourself to make sense of it, but no need to rationalise it. It's only good, cause you're used to it, or doesn't "feel more human" than Celsius.

I've been in a sauna with 100°C ( what's that? 250°F?) It's doable, but that's probably my personal max. So 100°C air temp is now 100%? Mmmh doesn't really work that great.

All in all, temperature unit is just data points, the interpretation is individual. Fahrenheit is not "more suitable for humans" than any other unit.

[–] [email protected] 1 points 1 year ago

I’m sorry you are having trouble making sense of it. It’s honestly a very simple concept.

[–] [email protected] 12 points 1 year ago (1 children)

Fahrenheit

0 = Well below freezing, about as cold as it gets anywhere that isn't frozen year-round. Dress like you're climbing Everest.

25 = Just below freezing, very cold but not record breaking anywhere people own snow shovels. Bulky jacket and gloves.

50 = Cold to cool, depending on your baseline. Put on a thick sweater or a jacket.

75 = Perfect, slightly above room temperature. T-shirt and shorts.

100 = About as hot as it gets anywhere that isn't a desert. Tank top and sunscreen, and stay in the shade.

Me setting my thermostat to 50 in winter:

[–] [email protected] 6 points 1 year ago

The main Fahrenheit I know is -40F.

Mostly because its also -40C.

Why do I care about water boiling when we're talking about weather?

[–] [email protected] 11 points 1 year ago (3 children)
[–] [email protected] 8 points 1 year ago

If you are regularly encountering weather that is boiling the water in your body, you may want to consider moving to a nicer climate.

[–] [email protected] 3 points 1 year ago

How frequently does the water in a human boil?

[–] [email protected] 1 points 1 year ago

Ugly bags of mostly water

[–] [email protected] 3 points 1 year ago* (last edited 1 year ago)

0 freezing

10 cold

20 nice

30 hot

[–] [email protected] 3 points 1 year ago (4 children)

Wait euro ovens are in Fahrenheit as well? I just thought it was our identity crisis measurements in Canada.

[–] [email protected] 3 points 1 year ago

Nah, mines in Celsius ... the poster above probably has an old British oven, they had a lot of hold-outs for imperial measurements.

[–] [email protected] 3 points 1 year ago

Canadians usually follow this. It isn't 100% correct, but close enough.

[–] [email protected] 2 points 1 year ago

I don't know if they generally are, but ours is lol

[–] [email protected] 1 points 1 year ago

No they are not

[–] [email protected] 1 points 1 year ago

I think 100 is when you have a fever

[–] [email protected] 1 points 1 year ago

Fahrenheit is nice for the ten degree ranges when talking. "Tomorrow it will be in the 70s". The entire range of the 70-79 is fairly nice and similar. Every ten degree range is meaningful and different. "Tomorrow it's in the 90s! :("

[–] [email protected] 1 points 1 year ago

Having used a lot of Celsius and metric in college sciences, they don’t bother me so much. But when it comes to certain applications, I’m more used to farenheight. For example temperature as it relates to human comfort.

Like I know 35 c is hot, and anything in the 40+ is miserable. But I also know I prefer temperatures to be in the 72-75 range for optimum comfort and thus have to do a bit of math if I need that in Celsius.
