For whatever reason, I don't comprehend Celsius intuitively. I convert that to Fahrenheit and see 80.6 degrees. Is Spain dry? Or humid? I would revolt as I much prefer cold.
I grew up with and actively use Celsius, but this instinctive disdain for other measurement systems leaves me… a little cold. It’s not even like Fahrenheit has weird non-decimal ratios. Save your mocking for the avoirdupois furlongs!
What's your standard of too hot? Uncomfortably hot? From the climate I'm used to then 80F qualifies. I'm not sure 80F is any less arbitrary a threshold than 25C. Don't confuse "my personal range of comfortable temperatures goes from 0-100F" with "0-100F maps neatly to every person's preferred temperature range and therefore is an advantage to fahrenheit"
(and that's before we get into the effects of humidity, or if outdoors, windspeed, on perception of temperature)
Similarly, 0F is -18C. -18C in my country would be a minor disaster, given our historical low is -5C. Our usual yearly low is about 0C, and 0C is more logical here than 32F, with negative temperatures actually being exceptional
As for personal preference, I think the first two thirds of that range are unbearable. I grew up in an subtropical area that regularly rises over 100 F in the summer. I don’t go around pretending that’s not hot though. It’s very hot! Unless you’re proposing different temperature scales for every climate, I’m unsure how your point about your local area is relevant. Surely people travel outside of your (and my) warm climate.
30C+ is too hot to go outside.
20-30C is a hot summer.
12-20C is the rest of the year.
0-12C is jumper weather or freezing to death in your home, depending on whether you can afford your energy bill.
<0C is fucking Baltic.
Celsius has many strengths, and is obviously better suited for scientific purposes. Fahrenheit is handy for outdoor temperatures. That doesn’t mean Celsius is useless for those.
These turf wars are weird. A good engineer doesn’t spur different tools, for different tools have different strengths. I can immediately make sense of both systems, and I consider that to my advantage.
Celsius and Fahrenheit are equally arbitrary / bad for scientific purposes, Kelvin is the only scale that makes sense since it's zeroed at absolute zero. Celsius is only marginally better than Fahrenheit in that you mostly deal with temperature increments rather than absolute values and celsius increments are the same as kelvin increments
In Fahrenheit 0 and 100 are defined in random ways, but it ends up covering most of the range of temperature human experience in the environment.
Celsius's definition does not include putting a thermometer inside an adult horse, but the common range of everyday temperatures is -18 to 50.
There are points of view in which imperial units can claim to be easier to use.
In the end the SI are technically better for sure; US imperial units are defined in terms of SI units, according to Wikipedia the pound is "legally defined as exactly 0.45359237 kilograms", nor it is a coincidence that -40F° = -40C°
I adore Randall.
Actually I had found it apparently but convinced myself that it was not the correct one, I deeply misremembered the setting.
It probably has an element of catharsis for people on the receiving end of "metric is superior" whining to point out celsius is not particularly rational
Yes, I get that, but that's what it will always remain — just a cope, but not much else.
The reason: Customary isn't criticized, as far as I can tell, based on how the individual units are defined. That wouldn't be really valid, because all base units are arbitrary, including those of SI.
No, the unit system is criticized as a whole. The way conversions are defined between each other, that's what makes them so much less practical. The fact that a foot isn't 10 inches, a mile isn't 1000 nor 10000 feet (hell, even 5000 would've been better). That 1 gallon of water doesn't weigh 1 pound.
In "daily life", both Celsius and Fahrenheit are mostly isolated scales – you don't relate them to other units very often, and you almost never have to convert them to anything else. So it doesn't really matter how they are defined — definitely not on the same level as length, mass or volume.
Anyway what I say going to say is there was a migration Path here which went along the lines of changing from a base-12 conversion to a base-10 conversion. So there suddenly was a customary unit and a transitional unit. After that metric base units were introduced
Both. Spain is one of the European countries with most diverse ecosystems. The local weather ranges from "tropical Mexico" to "Siberian winter". We have deserts and relic cloud rainforests. The inner core is dry and hot (not much unlike US pairies), the North is like Ireland and the West would be similar to California. Canary Islands are subtropical.
Currently most big cities are reaching over the 104ºF (40ºC). A pretty hot year. Environmental crimes made it much worse, so we are having a dry year also.
(Stupid note for myself: It seems that all the years with big wars are extra hot. Somebody should study how all this extra energy released locally by bombs and missiles interact with the weather models).
10-15 is nice perfect weather for outdoors.
I don't get why you said that most Europe is dry. Germany, France, the British Isles, the Netherlands, Poland, etc. aren't dry at all.
For instance, Bilbao is quite humid right now (about 80%), but max temps are in the 25°C. Madrid is expected to reach 39°C today, but humidity is about 30%.
20 is not.
30 is warm,
40 is hot!
Body temp 37c.
20c = 68f (room temp)
30c = 86f. (68 mirrored)
-20 is cold
-10 is cool
0 is cold and damp
10 is nice
20 is warm
30 is hot
40 is off the charts
