I'm happy with metric generally speaking - except for Celsius when talking about ambient temperature. I will die on that hill. Freezing/boiling point of water is a ridiculous point of reference for temperature as experienced by humans.
Fahrenheit: 0 = really cold; 100 = really hot
Celsius: -17.778 = really cold; 38.333 = really hot
Not to mention that the Celsius grading is too big requiring use of tenths when discussing weather and setting a thermostat...
What? I have never ever had a discussion in my life about tenths of celsius when discussing weather or thermostat. Nobody does that. The units are small enough to be used in majors.
Freezing is excellent point of reference when you think about what effects it has on our lives. When water freezes, roads get frozen. When water freezes, pipes might blow up. When temperature reaches 0 Fahrenheit, nothing happens. Everything is same as 1 fahrenheit, or -1 fahrenheit. Nothing has changed, it is completely arbitrary.
Many Celsius thermostats increment in .5 degrees. Both systems are completely arbitrary.
But hot and cold is relative. It's largely up to experience to have a feel for temperature. Eg, what temperature do you need a jacket in? In Celsius, around zero is jacket weather. What's room temperature? It's a pretty arbitrary 20ish C vs 70ish F either way.
I could just as easily say Celsius has nifty ten degree bands for weather. 0 to 10 is chilly fall weather. 10 to 20 is nice late spring weather. 20 to 30 is summer weather. 30 to 40 are the hottest summer days. 0 to -10 is mild winter. -10 to -20 are the cold winter days. -20 to -30 are the coldest days in a place like Toronto.
For outside weather, I've never seen anyone use tenths. Thermostats (for inside) in Celsius usually use half degree granularity.
I generally agree with you, but I guess how you experience these depends on where you live and what you're used to. For me, it would be something like:
- 30 to 40C: really hot summer noons
- 20 to 30C: nicest range overall. Summer nights and autumn/spring days.
- 15 to 20C: comfortable if you move around, working, doing sports etc
- 10 to 15C: starting to get cold. Need jacket
- 0 to 10C: winter cold
- -10 to 0C: my balls are freezing
- -20 to -10C: once or twice in a lifetime. Not going out at all until it gets warmer.
- < -20C: are you fucking kidding me?
Laughs in Canadian
Man, sometimes I'm relieved when it's only -20°C. At least my eyelashes don't turn to icicles.
Man, -15 is kinda nice weather for going outside and eat ice scream.
- < -20C: are you fucking kidding me?
Welcome to Finland!
-10 to 0C: Simply retract your balls to avoid this
Thermostats (for inside) in Celsius usually use half degree granularity.
I find it is hit or miss if a thermostat gives 0.5C or 1C for granularity. Even when the do have half degree increments I always just use whole degrees.
See, the problem with the Fahrenheit = percentage thing is that it DOES NOT WORK. how I am supposed to know how 50% of "very hot" feels like. ig it's something """neutral""". Oh wait it's 10°C, i need warmer clothing. You need to get used to a temperature measurement, however logical you think it is. Tenths are a non-issue.
Excuse my unprofessionalism
It works better than "-20 to 40" tho.
It's really hot for a human way before 100°F, it's becoming uncomfortable when it's more than 77°F (or 25°C for most humans. The "100 really hot" part is not really a benefit for anyone.
Also the point when water freezes is pretty important in the winter. You can see immediately that you have to drive carefully when the temperature is close to 0°C. So I think 0° freezing makes the most sense.
However: Temperature of boiling water is useless, that's true.
Sorry these arguments about the superiority or otherwise of a unit of measurement are just silly.
It is 100% related to what you grew up with and are familiar with.
No one who grew up with Celsius has any issue discussing weather or adjusting thermostats and the only people who struggle would be people who didnt grow up with it.
Sorry these arguments about the superiority or otherwise of a unit of measurement are just silly.
Well.. Yeah, of course.
Celsius: -17.778 = really cold; 38.333 = really hot
That looks silly because it's completely arbitrary, set to what you are used to. There is no universal "human experience". Where I'm from temperature typically ranges from -30 c to +30 c, which seems pretty nice and balanced compared to imperial's -22 f to 86 c which looks silly now, doesn't it?
It's all completely arbitrary.
Wow! I came here to tell about the time I had a discussion with an American about exactly this. And your arguments where the same as hers. I guess it simply is about what you are used to. For me Celsius is just fine and an accurate enough measurement. I know that I like my shower water to be exactly 37,3° C (98,6°F). And I can adjust my AC with decimals as well. But for the weather forcast: nobody cares if it's 27,2° or 27,7° C (81° or 82°). The forecast isn't as accurate anyway. So noone is talking in decimals when discussing weather.
Also: 32F (0 C) is still literally freezing cold! And even your "halfway" mark of 50F (10C) is still cold in my books.
There will always and forever be arguments about it and it all comes down to this: What ever you grew up with you are intuitive with and probably like it better. Celsius is subjectively more logical and Fahrenheit seems to "feel" more right for some.
Fahrenheit automatically disqualifies itself from being a serious unit, because it has an inconsistent scale
This reply really confuses me - in what way is the scale inconsistent?
The original definition is using three points:
- A random human's body temperature defined 96°F
- Freezing point of Water defined 32°F
- A weird Water salt ice mixture to defined 0°F
Because of that the scale of Fahrenheit was different above the Freezing point of water and below, requiring to redefine the temperature at the reference points multiple times (and not by an insignificant amount)
The original definition of Celsius (centigrade) was reversed with 100 being the freezing point of water and 0 being the boiling point. I'd say a "non-insignificant" change.
Kelvin?
Fahrenheit automatically disqualifies itself as a serious unit, because it has an inconsistent scaling, because it's definined using three points.
