I live in Philly, anyone see that eagles game yesterday? we got about 6-8 inches of snow(orig. was only supposed to get around an inch lol ) and we have round 2 coming tomorrow. and its going to stay in the 20s tomorrow yikes.

But Fahrenheit makes no sense. It's based on the stable temperature of a water, ice and ammonium chloride solution... like, what the hell?

At least Celsius has a concept that is easy enough to grasp. 0 is where water turns solid and 100 is where water turns gaseous. And the Celsius scale follows the Kelvin scale, which makes it far superior in science, obviously. Smiley: tongue

Scientists just make stuff up anyway. Well other scientists do; all my data is legit of course. Should have done 0-200 or something, would have made it more reasonable and useful to people who aren't chemists.

High/low temps for a week of 5C/2C, 4C/1C, 6C/2C, 10C/8C, 5C/3C...

Wow! Thursday looks warm!

Fahrenheit makes complete sense to use for weather temperatures because the scale is more or less based on how hot or cold things feel to humans. Thus, 0 is "really freaking cold", while 100 is "really freaking hot". Comfortable ranges are those in between. 0 is the freezing point of brine. 100 is just over human body temperature. It's a great measurement to use when determining whether things feel hot or cold.

Celsius is great for laboratories, where knowing the temperature relative to the freezing/boiling points of water is useful. But not so much for the weather channel.


Oh. And for the record. It is cold. OMFG! It's supposed to get down to the mid 40s tonight. Brrrr!

As for the actual weather, it's the same all year around here, anyway. Except it hasn't hailed in like 2 months now.

Knowing when water freezes is arguably more useful for your daily routines than knowing if it'll be chilly or not. It's the difference between getting a cold and wrapping your car around a tree.

Pretty sure you can figure out frozen water without a thermometer.

Sure, if you leave a glass of water out at night, but black ice is not that easy to spot.

Celsius is difficult for describing how temperature differences feel to us. Relatively speaking, of course. But it is just perfect the way it is for the conversion from F to C (0 - 200 would be too confusing) because the difference between freezing and boiling water is 100 degrees in C and 180 in F (212 - 32).

In fact, it's a snap to go from C to F, just take the temp in C (say, 20C) and knock off a fifth (so, 16), then add that back to the original temp (to total 36) and add 32, and it's a balmy 68 degrees F. If it's 22C then do the same and add an extra 1.8 degrees for each extra degree C (or 3.5 in this case) for 71.5F. If it's 19C then subtract 1.8 degrees for 66F.

Now, going the other way is a bit more difficult because you have to subtract 32 (36) and multiply that by .55 to get . . . a little over half, or 20C.


Anyway, it is always hot in our office suite. The building claims it's because we are first in line for the heat *********** My office is always the hottest office in the suite. I feel they should lower the heat but the ladies complain then because it's too cold. But they can wear sweaters, I can't start stripping down (well, I could, but that would be like dividing by zero - something very bad would happen to the integrity of the space-time continuum).

But, the upside is that today one of the women wore a sleeveless thing because she was expecting it to be very warm in the office. Smiley: yippee Smiley: yippee Smiley: yippee And like a prepubescent teen, I kept looking for reasons why she had to come into my office to help me understand this or that. Smiley: sly

You'd be surprised.

Anyway, my point is that water is a very known and relevant substance to most people, and using a scale based on its states makes it easier to understand and work with, in terms of weather analysis, than using a scale based on another scale that was based on the freezing and boiling points of brine.

It just seems absolutely ridiculous that anyone would refer to +32 as being a freezing point. +/- 0 makes more sense, to me.

Snow is supposed to start here by 11 and continue into the night. Smiley: glare

Most schools in the area are closed already.

I, thankfully, am working from home or taking a sick day. Woke up super dizzy and couldn't have commuted to work even if I wanted to.

I don't think I've met anyone who doesn't know that below 32 is freezing. At least for people who live here.

And the freezing temperature only matters during the winter. Summer/Spring/Fall all do much better with the temperature scale offered by Fahrenheit.

And, honestly, the scale of experience is better in winter, too, because your experience is more directly mapped to the temp.

<0 is REALLY FREAKING COLD, >100 is REALLY FREAKING HOT. 50 is cool.

It just works well. I can hear the temperature and know exactly how I feel about that. I don't need to know what -2F is like to know I don't want it. But -2 in Celsius isn't really that cold.

I hear 100F and know it's going to be hot. 40C (or whatever) just doesn't have much of a zing to it. It's so close to 32C, which I'm guessing is much less hot.

That's a non argument though as it's purely reliant on what you're used to and I could use the exact same argument for Celcius.

I know instantly that, say 25°C is going to mean warm but not too hot and that -5°C means that half of the Netherlands is pitching a tent over the possibility of an Elfstedentocht.

40 ºC and 32 ºC are both hot. The human body is 35 ºC. Room temperature is generally considered around 20 ºC.

I guess the freezing point plays a larger role in countries that don't have as defined seasons as you have. I mean, look at this:

Quote:
Copenhagen (that's us) and Oslo have an average July maximum temperature of 22 °C (72 °F).

Quote:
In Denmark, January temperatures average between −2 °C (28 °F) and 4 °C (39 °F).


The mean temperature in our coldest month is 0 ºC (32 ºF).

When you live in a country where the temperature might go from "it's raining and the roads are wet" to "it's snowing and the roads are ice" ten times a day, water's freezing point is sort of important.

Eh, most people are aware that water freezes in the low 30's. That's good enough because it's not as though all the water magically turns to ice at 0 degrees Celsius anyway. Especially on roads, pavement temps, traffic, road salt, etc will play a big role in it. Bodies of water based on their size, composition and water movement, etc.

"It's 30F out there, stuff's gonna freeze" is accurate enough for essentially all lay purposes. You might not like it but it works peachy over here.

Except that Fahrenheit gives a clearer picture of temperatures than Celsius does with much less thinking.

Our temperature scale is more directly mapped to experience of temperatures. Negative temps, without ANY more thought, tell me it's going to be really frickin cold. Not much more matters. Bam, done, no more debating what to wear - it's "put on every single bit of clothing I own" weather. I don't need to think about numbers at all.

Because I'm not looking to think, I'm looking to glance at the weather and just make an intuitive choice about what works.

Sure, you'll adjust to ANY system. We could be using a system that just uses 10 degree ranges represented by various fruits and we'd all adjust to it.

But that doesn't mean it's not more intuitive to have a system that scales from, essentially, 0 to 100 that is more closely based on human experiences of temperatures rather than scientific meaning of those temps.

Because literally the only reason I care about the weather temperature is due to my experience of it.

Is it a huge deal either way? No. But our system IS more intuitive for weather. Celsius is essentially better for everything else (and for scientific discussions of temperatures), but when we're just talking about how hot/cold it is, the system that's more closely mapped to a linear progression of temp from "really ******* cold" to "really ******* hot" just makes more sense.

And you know that for, 85F or 95F as well as I do for 30°C or 35°C. Fahrenheit is more intuitive to you because it's what you know and have known for all of your life, Celsius requires as little thinking for me as Fahrenheit does to you and any argument that it's "more closely related to how you experience weather" is just *********

Are you honestly going to argue that a system that's mapped 0 to 100 with close relevance to our experience of temperature isn't more intuitive? Because I'm positive I can give you a solid counterexample.

And we'll go ahead and ignore the fact that base 10 mathematics makes a 0-100 scale quite accessible just in basis of the way we're taught to approach numbers.


Here's the scenario? And it's one I've encountered many, many times because no one ever actually knows what the temperature is*.

"Do you know what the temperature is outside?"
"No, it's negative though."

That tells me literally all the information I need. Whether or not it's -2 or -12 no longer matters, because I'm going to behave exactly the same both ways - bundling up to the absolute maximum, and avoiding going outside like the plague. Why? Because we are using a temperature system that is set so that anything in the negative range is far below what we want to be dealing with.

Same thing with temps over 100. I'm going to do pretty much everything in my power to not go outside, regardless of if it's 104 or 110.

Maybe it's culturally more common to have any clue what the temperature is over in the EU. 95% of the time, if you ask someone in the US, you'll get an answer of something like "In the 80s" because they remember the tens digit but not the singles unit.

You do that with Celsius and it's a much, much larger range of temperatures. Celsius requires me to know more information than I'm inclined to passively commit, and that makes it fundamentally more difficult to use. You can't even get the same exactness as when someone says "low 60s" with Fahrenheit, because "low" is going to be about equal to a full Fahrenheit tens-range in Celsius.

Yeah, if I know it's precisely 68F degrees or 16C or whatever, then they're pretty much equal if I've adjusted to them (such as by growing up with them). But unless I'm looking up the temp on a weather service (which I don't often do - my weather extension on chrome broke 4 months ago and I haven't bothered fixing it), I don't have that info.

So my point remains. Fahrenheit, by being so closely mapped on a 0-100 scale relative to human relationship of temperature to what it feels like, is FAR more useful and intuitive for day to day life. So little is placed on me, the person using the system, to know much of anything. At the worst extremes, the scale makes it quite clear without any extra thought. And for everything in between, a little bit of info goes a long way.

Celsius requires you to be more exact, and ain't nobody got time for that.

Because "high 60s" or "around 15" are so different in accuracy or how easy they are to say.

And the whle closely related to how humans experien e weather makes no sense. Tell a Russian in Siberia that it's going to be 0F he'll be happy that it's not cold and if you tell Horsemouth it's going to be 0°C where he is he'll freeze to death just thinking about it.
