A few years ago I started using Celsius in my everyday life. It’s been pretty easy, just remember that C scales twice as fast as F, and 32F=0C and you’re set for conversations. It helps to be quick with math, but finding it difficult may make it easier to convince other people to use it instead of F near you. To acclimate yourself you’ll want to change the settings on your phone to use C by default.
I haven’t switched over to m in everyday use, because all the roadsigns are in Mph and doing that conversion while driving is bad juju.
I’m thinking of rewriting all my recepies in grams and liters. If I can figure out how to get our stupidly-over-designed-yet-entirely-jank oven to use C, that’d be good too. If we had one with a bimetalic strip and a knob I’d be able to just print one with the new temperature scale.
Honestly, temperature (in terms of weather preparedness, not cooking) makes WAY more sense with Fahrenheit. Largely the only temperatures you care about are 0 to 100 and generally you feel a good difference in temp every 10 degrees F.
Almost everything else I prefer metric. But that’s one where Celsius is just terrible.
That’s a poor argument, though, when the justification for utilizing volume, mass, and distance is because it is very “base 10”-y and is easily divisible and understood.
Celsius absolutely is shit for that.
I could use your logic to justify why imperial units are better for length, for example, but we all know it’s a bit fucked. Celsius is absolutely fucked for temperature regarding human comfort and is imprecise.
Replying again because you’ve edited your comment and added another paragraph.
Your edit asserts that Celsius is “absolutely fucked” regarding temperature for human comfort… which is an utterly bizarre argument to make because it only makes sense to people who are used to Fahrenheit and have an intuitive sense of what 72F means to them, but have no intuitive sense of what 22C means
I’m not entirely sure that you’re not just trolling now.
No negative numbers needed for most cases, 0-100 scale for the extremes MOST people need to care about with relative “feels like” every 10 degrees (but realistically every 5 is distinguishable, even smaller amounts depending). Ez pz.
IDK why you’re so defensive about Celsius lol. It’s okay to admit when an SI unit has a poor application. Your ONLY defense for it is “well people can get used to it” which is the exact same reason I could say “well you could just get used to feet, inches, yards, miles, pounds, ounces, fluid ounces, teaspoons, tablespoons, etc” - it’s a shit argument for both.
But oh that’s right this is Lemmy where “america bad” for everything.
Right, so…once again, your argument is that you feel that Fahrenheit makes more sense, because that’s what you’re used to
I never said that C is better because people can get used to it, you’re just making that up. I said that the system people are used to is inherently going to be the one that makes the most intuitive sense to them, and that applies to both C and F.
The rest of what you said applies equally to any system of measurement.
I don’t understand why you’re so angry about this?
Tread lightly my friend. I already won the Fahrenheit vs. Celsius debate a few months ago, but non-Americans are insanely defensive about the metric system and won’t accept the truth.
I’ll transcribe my best arguments because that thread was an absolute shitshow and it’s hard to find my comment even with the direct link. Almost all of my most downvoted comments on Lemmy came during my defense of the Fahrenheit temperature scale, and I’m weirdly proud of that fact.

Celsius is adequate because it’s based on water, and all life on earth is also based on water, so it’s not totally out of our wheelhouse. But for humans specifically I think Fahrenheit is the clear answer.
One point that many may overlook is that most of us here are relatively smart and educated. There are a good number of people on this planet who just aren’t very good with numbers. Obviously a genius could easily adapt their mind to Kelvin or whatever.
You have to use negative numbers more frequently with Celsius > Celsius has a less intuitive frame of reference
Each Celsius degree is nearly two Fahrenheit degrees > Celsius is less granular
The reason I argue the more granular Fahrenheit is more intuitive is because a one degree change should intuitively be quite minor. But since you only have like 40 or 50 degrees to describe the entire gamut of human experiences with Celsius, it blends together a bit too much. I know that people will say to use decimals, but its the same flaw as negative numbers. It’s simply unintuitive and cumbersome.
B) 66F is room temperature. Halfway between freezing (32F) and 100F.
the intuition is learned and not natural.
All scales have to be learned, obviously. It’s far easier to create intuitive anchorpoints in a 0-100 system than a -18 to 38 system. Thus, Fahrenheit is more intuitive for the average person.
I should note that if you are a scientist, the argument completely changes. If you are doing experiments and making calcualtions across a much wider range of temperatures, Celsius and Kelvin are much more intuitive. But we are talking about the average human experience, and for that situation, I maintain Fahrenheit supremacy
It’s not about the specific numbers, but the range that they cover. It’s about the relation of the scale to our lived experience. Hypothetically, if you wanted to design a temperature scale around our species, you would assign the range of 0-100 to the range that would be the most frequently utilized, because those are the shortest numbers. It’s not an absolute range, but the middle of a bell curve which covers 95% of practical scenarios that people encounter. It doesn’t make any sense to start that range at some arbitrary value like 1000 or -18.
When the temperature starts to go above the human body temperature, most humans cannot survive in those environments. Thus, they would have little reason to describe such a temperature. Celsius wastes many double digit numbers between 40-100 that are rarely used. Instead, it forces you to use more negative numbers.
This winter, many days were in the 10s and 20s where I live. Using Celsius would have been marginally more inconvenient in those scenarios, which happen every winter. This is yet another benefit of Fahrenheit, it has a set of base 10 divisions that can be easily communicated, allowing for a convenient level of uncertainty when describing a temperature.
Generally -40 to 40 are the extremes of livable areas.
Sure, water is a really good system and it works well.
And for F that range is -40 to 104. See how you get 64 extra degrees of precision and nearly all of them are double digit numbers? No downside.
Furthermore F can use its base 10 system to describe useful ranges of temperature such as the 20s, 60s, etc. So you have 144 degrees instead of just 80, and you also have the option to utilize a more broad 16 degree scale that’s also built in.
You might say that Celsius technically also has an 8 degree scale(10s, 30s), but I would argue that the range of 10 degrees Celsius is too broad to be useful in the same way. In order to scale such that 0C is water freezing and 100C boiling, it was necessary for the units to become larger and thus the 10C shorthand is much less descriptive than the 10F shorthand, at least for most human purposes.
What’s funny is the person who brought up arguments FOR Fahrenheit over Celsius to me that I hadn’t considered is actually a Brit. They lived in England and the US and your explanation here is very similar to theirs.
You certainly didn’t win any arguments with those claims.
0-100f is not anywhere close to the scale people see in the weather anywhere most people live. Taking where I’ve ever lived as an example:
Melbourne ~ 30-120 f vs 0-45c,
Gladstone QLD ~40-120f vs 5-45c,
Pilbara ~65-130f vs 15c-50c,
Dubai ~55-120f vs 20c-45c,
Houston TX ~ 30-120f vs 0-45c,
Pittsburg PA ~10-90 vs -15-30c.
The most iimportant number with respect to the weather is freezing, it’s handy knowing if you’re dealing with ice. The standard range for where people live is not -40 degrees, something like 2/3 of the world live between the tropics and will never see freezing or below. The -40 number makes sense if you live in Alaska or Siberia and maybe even somewhere like Minnesota, but certainly not to someone in India or Indonesia…
Neither scale is relative to cooking (which isequally arbitrary for both), though metric is easier for things like brewing 80°C tea since you need 4/5th a cup boiling water and 1/5 a cup and no thermometer.
The “feel” of the weather is hugely impacted by humidity which is why every forecast has a “feels like” measure and why 90°f in Dubai is lovely but 90°f in Houston is miserable. The increments of 10f doesn’t make sense at all, though seems to be a common perception among people who prefer fahrenheit
The comment about farenheit being more granular would be true in an alternative universe where decimals don’t exist, but not in this one.
Americans literally like farenheit more because it’s familiar, any other rationalisation is nonsense. Both measures make perfect sense after you’ve taken the time to learn them and use them daily (I know this firsthand).
The increments of 10f doesn’t make sense at all, though seems to be a common perception among people who prefer fahrenheit
What doesn’t make sense about it? You can tell another person it’s in the 30s outside, and you have efficiently communicated more information than is possible when using Celsius. You’d have to say it’s between 4 and negative 1, which is just lame. And this remains true across every temperature, because of a variety of factors which I explained above.
In every climate which you mentioned above, it’s easier to communicate how hot or cold it is outside using Fahrenheit. This is because all of the numbers being used are non-negative integers (aka natural numbers). Even the triple digit ones are one-ten or one-twenty.
I wonder why mathematicians named them that? Possibly because they come naturally? Unlike negative one point seven.
They will defend Celsius being used for everyday weather reporting with their last breath with their ONLY fallback being “well you’re just used to fahrenheit durrrrrrr” as if that logic can’t be applied to every unit system on earth.
Yeah. I’ve had some time to ruminate and I think part of it stems from the impossibility of them not using Celsius in their lives. Like, they’re not going to singlehandedly make their country start using Fahrenheit, so accepting it as better would just create cognitive dissonance.
as if that logic can’t be applied to every unit system on earth.
Mate that’s my whole point. I grew up Celsius in Australia and use Farenheit day to day now. They are literally interchangable once you learn. It takes a month or two to get used of using them and beyond that, the literal only difference in difficulty of use is that it takes about ten seconds longer to calculate a green tea brew in f, which has no bearing on the weather anyway. All of the arguments above are garbage, as they are garbage when the exact same, inverted arguments are made by metric proponents.
All measurements scales are interchangeable once you learn - that’s not the point of this particular thread of comments. It’s “what’s most useful comparatively given the SI penchant for base 10”. The answer isn’t a temperature scale that, for day to day human concern, is not -18 to 38 - that’s fucking stupid.
Why do yanks insist picking such idiotic numbers when they speak in metric, seriously wtf is -18 to 38? If those were realistic temperatures, surely you realize it would be -20 to 40, no?
-20, or any negative c, is rare to most ff the worlds population so your comment is dumb on two fronts.
What doesn’t make sense about it? You can tell another person it’s in the 30s outside, and you have efficiently communicated more information than is possible when using Celsius. You’d have to say it’s between 4 and negative 1, which is just lame. And this remains true across every temperature, because of a variety of factors which I explained above.
It doesn’t tell you anything that Celsius can’t with a 5 degree swing. This the absolute peak of arbitrary, both 5s and 10s are easy scales to work with. Your example of between 4 and negative one is deranged. I’m in houston right, it’s 90°f - if I want to comunnicate that to my yankee girlfriend I’d say “babe it’s 90° outside, might get up to one hundred” and so far, you’re right this is easy to articulate. If I want to communicate that same information to my mum, I’d say “hey it’s 30° outside, might get up to 35°”. Both cases convey information with the same accuracy, both cases I haven’t mentioned humidity, which for actual temperature feel has a way higher influence then 5 degrees, the extra information I’d gain by strictly converting 31-37.8°C is junk data, the farenheit measure is approximated to begin with and because of a humidity swing carries a huge variability in actual “feel” anyway. I tried to explain this above and clearly failed, as your response doesn’t touch on this at all and just insists that people who think in metric don’t default to easy to work with numbers.
In every climate which you mentioned above, it’s easier to communicate how hot or cold it is outside using Fahrenheit. This is because all of the numbers being used are non-negative integers (aka natural numbers). Even the triple digit ones are one-ten or one-twenty.
The only place with negative integers was Pittsburg, so that point doesn’t make sense for the rest and even if it was, your argument is insane. Saying negative 5 is no harder than saying 25, plus having negatives where snow and ice come into play makes it obvious when to be careful outside. I mean your argument here just makes no sense, if there is some added complexity to saying “negative” then it is surely comparable to having to remember a random number of 32. Literal kindergardeners understand negative numbers. Neither this or remembering the 32 number add any meaningful complexity and certainly have 0 impact on anyone’s actual use of either scale.
Literal adults have trouble with negative numbers. I can’t do this all over again, sorry and have a nice day. Hopefully it’s somewhere in the 80s wherever you are
Mate I have to reply to that, because it’s such an insane claim - the US, the only country that doesn’t use °C, has this huge reliance on a monstrously complex credit system (obviously the entire concept of credit is reliant on the concept of debt and negatives). It’s flat out insane to suggest that the same people who live and function with such a credit system conceptually struggle with the fundamentals negative numbers. It’s a mind boggling claim.
Yes, as we both know, there aren’t any Americans who struggle with a low credit score and end up with insurmountable debt…??? Credit is reliant on debt and negatives, and people get screwed by their lack of understanding it every single day. Same with the lottery, except with big numbers and percentages. America is profoundly dysfunctional and it’s frequently the people who are bad at math that get exploited.
So, uh, no? In fact within the “human spectrum” you generally care at least somewhat about every tick of the number. So it’s actually more useful for people.
Because I doubt you can feel the difference between 71f and 72f. But it’s possible to notice the difference between 21 and 22, although you’re pretty picky if you do.
A few years ago I started using Celsius in my everyday life. It’s been pretty easy, just remember that C scales twice as fast as F, and 32F=0C and you’re set for conversations.

The entire point of this post under which we are all commenting is insinuating a superior system of measure. Jesus you actually are this stupid.
So… in your opinion, Celsius is shit because you’re not used to it ?
Tell me you didn’t read the argument without telling me you didn’t read the argument.
Ah yes, more insults. Your argument of ‘the system I use is better because I abuse people who disagree with me’ is very compelling indeed.
Saying that you didn’t read my argument because your point ignored it entirely is an insult? It’s abuse? LMAO.
Are you fucking stupid? <- that is an insult
…says the person who has literally been swearing and insulting me in every reply.
Blocking you now. I don’t need your childish insults in my life.
no.
Brilliant response.
🤷♂️ it was as much as it deserved.
Could just admit you’re a stupid cunt and move along
oh, sweetie, no.
no.
Oh, honey, yeah.
Yeah.
