This is why I'm Fahrenheit gang all the way. I'm not running lab experiments daily, but I am going outside all the time. If you have to express the temperature with decimal precision for everyday use, you've lost.
Edit: It's hilarious how easily you can piss people off by saying Fahrenheit is subjectively better as a human temperature scale. Too much of your identity is wrapped up in being able to talk temperature in multiples of ten, people. Chill out. Maybe something near 42 degrees. Sorry, meant to say 5.6 degrees for the nerds in here.
What? No one's using C to that precision outside the lab. It just depends on what you grew up with man. I know below 0 I need a winter jacket, ~10C chilly, ~20C is shorts weather, ~30C is hot, >40C is death. Perfectly practical everyday estimations.
For me the only advantage of F is you can say it's 69F out and bake things at 420F.
Also let me point out one nice feature here - the freezing point is 0. Bellow it you can expect snow instead of rain, ice on the road, sidewalk, plants are in danger, etc. A lot of things and situations in your life are affected by this simple fact that water freezes so it's nice that we have it at 0.
Fahrenheit has 32°F ...
And water boiling at 100C is useful too because boiling water is used so often in cooking.
I gotta ask, do you use a thermometer to boil water?
Metric is a more coherent system, but let's not pretend it's magic or more than it is.
The numeric value associated with boiling water has no impact on cooking, because the boiling water doesn't care.
No, but I use a thermometer (built into the electric kettle) to prepare tea. Greens want to be brewed at 75-80C. Whites are often about 70C. Oolongs are about 95C.
But the human who is doing the cooking might care.
Well, it usually doesn't actually start to freeze and snow at 32/0. It's usually got to be below freezing for a while before it gets icy, and it'll often snow above freezing and sleet below. It's usually more dangerous if it's above freezing because the layers of melting ice make the unmelted ice far more slick.
It's why for weather information, it really doesn't matter what scale you use so much as knowing where those bands are on the scale you use.
The peril is a gradient, so the actual number that matches freezing really doesn't matter.
At least that's my take as a person who lives somewhere where cold weather conditions are a frequent topic of conversation.
The temperature itself doesn't start to get perilous until you're in the negatives on the Fahrenheit scale, or -17C.
When pizzas call for 425°F, I purposely set the temp at 420° because of course
the food poisoning is so worth it edit: guys chill, it's just a joke, i know you don't actually have to cook pizza
Uh, what? You do know you can cook pizzas at different temps to affect crust consistency, and that as long as meats are cooked to a proper internal temperature, bacteria is killed?
I'm not expert in Fahrenheit but that difference doesn't feel like it'd make a difference
More than that, the temperature gradient inside the oven is far greater than that difference
I agree with most of that, but I have been in Phoenix, AZ in ~42°C. Sure it wasn't pleasant, but I'm not dead.
Edit: For extended periods, absolutely. For AC building hopping, survivable.
That is a slight exaggeration, but I know here in Australia if you went out in 42C with no sun protection then yeah, you're not having a good time and it is a risk to life.
In July 2023 in Phoenix on the 20th and 25th it was 119° F or 48.3° C. Not as much an exaggeration as I would like it to be.
It's regularly 79° F to 107° F or 26° C to 41° C in Phoenix in summer. Lately it's been hotter (past 5 years)
At those temperatures, dry or wet, it's still gonna be dangerous.
Not trying to argue here, but the fact those were both last year should be enough of an indication to our political "leaders" that climate change is a major threat.

People who use Celsius don't typically casually refer to the temperature with a decimal place.
The comfortable range is more compressed, but just like you probably say 75 instead of 74.5, they say 24 instead of 23.889.
Fahrenheit does coincidentally line up nicely for subjective weather scales, so it's not offensive for that use, similar to how pint is a good cup size, but in general consistency is king and you're not loosing anything by compressing a scale, particularly when we basically already measure the temperature in five degree increments, and generally refer to in in units of ten.
As a metric person, I can confirm.
Indoor temperatures are basically 18-22 for most people most of the time.
15-25 covers the whole range of indoor temperatures that people with functioning heat or A/C would see.
For temperatures outside we commonly round to the nearest five:*
The only thing I admire of the Fahrenheit scale is that it can round to the nearest 10 and still be a little bit more precise than Celsius with the nearest 5. And when discussing fever temperatures, Celsius needs half degrees and Fahrenheit does not.
But it's an absolutely awful scale for cooking.
Rounding Fahrenheit temperatures to 10 is less precise than rounding Celsius temperatures to 5.
which temperature unit requires using decimals?
Have you ever stayed in a hotel with the wall thermostat set to C? If so, press the up/down temperature buttons. They'll move by 0.2 or 0.5 usually.
Maybe someday a metric country will take 13th place for walking on the moon
Guess which system NASA uses
I refuse
Chuckled at this. Well done
Pre- or post- Mars orbiter?
Well they did for the moon landing, and have as a policy since 1979.
I didn't know about why that orbiter failed though, pretty funny!
The orbiter failed because while NASA used metric, the contractor (Lockheed Martin, I believe?) used imperial for one system and no one caught their mistake.
When I'm reading through dates, January gives me a hell of a lot more information than "the fifteenth"
Then use ISO and start with the year, which gives you even more information.
Wtf are you talking about? You're the one that brought up how your favourite unit is superior, and we're the one that has our identity wrapped up in something?
Do you know how math works? Of course you're gonna end up with decimals when you're starting from F. Why don't you chill out at 11? Oh, I mean 51.8 you narcissistic swine.
I'd just say 52, but keep raging.
Ok, and I'd say 6? What's your point lmao
My original point was that Fahrenheit is more useful as a gauge of human comfort temperature.
But now you've made my other point that there is a not-insignificant number of people, like you, who's identity is so wrapped up in the perceived superiority of all things metric that you get your panties in a twist at the slightest challenge. It's honestly funny.
I mean, look at you for example. You voluntarily joined a conversation to go off on an unhinged rant and call me names. Just take a moment to think about your life and the choices you've made to bring you to this point where you lose your shit over a unit of measure.
You shat in the middle of the room, calling everyone names, and when everyone get annoyed you don't get to get on the high horse my guy.
You're the one that made the unprovoked comment on how your favourite unit is better. You're the one that called people nerds for some reason. You spent hours replying to dozens of people and you call people unhinged? Have you looked in the mirror? You're literally doing what you're making fun of me for doing but tenfold my friend. You're the one that started saying your team is better for no reason. And when people point out you made no sense you make fun of people for replying? Are you okay?
Do you honestly think you're winning? You're trolling people? Trolling used to take effort back in my day. know what, it's my fault. People always say you shouldn't argue with dumb ass because they'll drag you down to their level and win with experience. I voluntarily touched the poop.
Stay mad lmao
I don't think it's necessary to do in Celsius though?
"Necessary" is a strong word, but it is, moreso than when using Fahrenheit.
Weather, cooking, at least people around me don't use decimals for that. One degree C is not really big enough difference for those two to break down into decimals. Moreso I guess in the sense that one Fahrenheit difference is smaller than the same for Celsius. Do you know people using decimals for daily stuff with C?
I think it's a straw man personally because most people will still talk in integer amounts.
... You don't. But I find it funny when failheit rounds to the nearest 10s in conversation.
And believe it or not Celsius is much better for outside because it's actually zeroed to the actual fucking weather.
I never round 10 degrees, that's crazy. Definitely to a nearby whole number though.
"What's the temperature going to be today?"
"I think low 60s in the morning and 75 or 78 for the high."
So, maybe a 5 degree range max.
Dude you just did it, "low 60s".
I see it even on weather forecasts "We're going to get into the high 70s" which I think is what you didn't want to say, so you now specified 78.
And it's still a completely floating, arbitrary scale.
???
You do know that low 60s is not a 10 degree span, right? Right??
I'm beginning to see why some of you can't handle Fahrenheit units of measure...
ETA: Sure, I might say something like "upper 70s for the high" if I don't have any better Idea but, again that is not a 10 degree span of temperature units. Please, for the love of all that is holy, tell me you understand that basic premise of communication?!
You don't need decimals for everyday measurements. No one can tell the difference between 60 and 62 degrees F. With Celsius 10 or 5 degree ranges is all you need to know for weather purposes, and it falls into much more logical ranges.
Below 0 = cold, limit time outside 0-10C = wear a coat 10-15 = wear a jacket 15-20 = comfortable 20-25 = shorts 25-30 = hot 30-40 = limit time outside 40+ = thank you global warming; don't live here.
This is true in the sense that someone can't walk into a room and say "it's 62F in here" accurately, but if you're in a room that's 60F and you raise the temperature to 62F you can definitely feel the difference.
We all subjectively are more used to our scales, and what numbers mean "very hot" and "very cold" are very varied based on your physiology, adaptation to the climate and the relative humidity.
For water, however, freezing pretty bang on zero (slight variation due to pressure), and you get enough days below zero water of different amounts will start freezing. Which I'd argue is an objective benefit over Fahrenheit for weather. Water freezing at zero is a useful distinction.
Negative? Freezing. Looks great on a graph with an X axis for time and y for temp. To get the equivalent nice graph in Fahrenheit gotta put a line at whatever weird number lines up with freezing.
A random city which I thought may be dipping below zero. That's interesting, there's a line at freezing, almost like that's useful or something.
Putting a line that's not zero, look at what Fahrenheit needs to do to mimic a fraction of our power!

And you can't go outside when you're too dense to read the temperature?
