Because no matter what the temperature is outside, if it’s measured in Fahrenheit you know you have the freedom to go enjoy the weather *eagle screeches*
I kid. But- in all seriousness there actually are arguments in favor or Fahrenheit and other si measurements in various circumstances. This is especially true in temperature where while one can argue that Celsius has certain conveniences in a lab, most are useless or even potentially a draw back in “everyday life.”
A simple example is that a whole number F scale is generally more intuitive, 30 degrees is very cold but you can dress for it and go out. 60 degrees is generally pretty pleasant. 100+ is hot. Celsius expresses that same range on a scale of 0-37 in whole numbers. Which is the next thing- the range between 1 degree F is 1 degree. You can feel that but unless you are doing chemistry etc. a decimal generally isn’t needed. You can round off in F easily.
In C decimals are required to express increments of change a human can feel- and negative numbers are required to express any temperate below the freezing point of water.
In simple terms- C is based on the behavior of water of a given composition at a given altitude under given conditions and has very little to nothing to do with the way most people relate to, use, or care about temperature across most of the globe where water doesn’t even meet the specs and doesn’t actually freeze or boil at the temperatures used as proofs for the scale for scientific use. There are reasons that you don’t generally see speed limits like “14.7kmh (or mph)” and such. It’s generally easier to deal with and think using whole numbers for most things that don’t require that degree of precision. There are other cases to be made too. I like metric and do almost all my measurements in metric except for some home repair and such as US building materials are often sold in or made in si increments. Of course…
.. I am used to si units and having fuel sold by the liter or not buying milk by the gallon wouldn't be a huge deal, just something to get used to when I went to the store to pick up my 3.785 liter container of milk, and that might make some recipe a chores and such but no great loss. Celsius is a booty way to do temp though. Science even rejects C for K because Celsius even fails in the lab unlike most metric which works well for science and such. So personally I think Celsius is booty, but I would t cry if we went metric except for temp. Regardless it is all a bit nit picky as the average person doesn’t really need to worry as long as they can look at the weather report and know what to expect. We could use a temp scale from .092737-.0927375 where .092747 equaled -20C if we wanted to. It’s arbitrary. If you stop and think about life using that system you’d probably say: “this system is booty…” and well… yeah. That’s what C looks like compared to F too. It’s booty.
I understand what you say, but the temperature unit for metric system is the kelvin, not the Celsius, and it's more common in science because as you said it its according to pressure and altitude of water, but because it's so more easier to convert to kelvin that the farenheit, and as you also solid, you con feel the difference in 0.1 degrees and not in 20
Kelvin and Celsius are metric. Same increment different degree, but as far as I know no countries use Kelvin in daily use like reporting weather or general temperature reference. But indeed- it does seem a bit unintuitive and a little extra to say that it is 260 degrees outside Vs. -13.x C or 10 F. If one is used to the Kelvin scale it works fine and you’d know how cold it was but it is slightly longer to write or say that same temperature in C or K than F, which requires two character fields to display or two numbers only vs. 3 fields and three numbers or two numbers and an operator for K and C respectively at the same temp. One thing that would be nice if metric countries adopted Kelvin for general use like weather and such is that it would become VERY unlikely that anyone could misunderstand the weather at a destination as the wrong scale like between C and F where it is at least possible to misunderstand if a place is rather warm or rather cold lol. I guess in baking or such….
F and K are close enough to ranges that make sense to mix them up, but F based cooking temperatures are almost always round numbers and sometimes increments of 5 degrees (450,325,etc) and outside of some VERY niche candy making or complex dishes F cooking temps are essentially always whole numbers, so if you saw 477 or 478 degrees you could probably assume it was Kelvin I suppose.
Silly addition to this .. In the nineties I was reading up on fusion in the Tokamak, which was estimated to become our greatest energy source withing 25 years, and it said that the Deuterium-tritium fusion reactions require temperatures in excess of 100 million degrees but it didn't say in what unit. So ofc young autistic me wrote to the project and asked in what unit that was. The reply was that it didn't matter because the difference between F, C and K at those temperatures wasn't measurable or meaningful.
Thank you for the sweet and interesting story. I think it is cool that you thought of that and had that curiosity. The reliance seems a bit… terse? To the request, especially from a younger person.
And I mean- I guess in general terms it doesn’t matter since we are talking about temperatures that are just near unfathomable- a bit like wether a star is 600 trillion light years or miles or km away- it CAN matter but as far as most things are concerned we know that it isn’t likely we’d ever reach it or that in human terms it would make a difference. That said I mean… C to K we can call it “close enough” but K to F that’s like a difference of 70% or so. Not really a practical concern but still…
