The reason we even care is that maintaining two systems is heavily impractical and adds to confusion all around the world - simply because 4% of world’s population can’t bother to make a change.
We wouldn’t care what you use - perfect barbecue temperature scale, length unit of football field, weights in blue whales - if it wouldn’t affect the rest 96% of the world who have to decipher your blubber.
Everyone uses Celsius and metric, make a damn switch, it’s not that hard and you won’t lose anything. You only use it because you’ve used to it, there is literally nothing else to it. Everyone switched, everyone’s happy with it. Do it already.
P.S. Also, Fahrenheit is currently officially defined through Celsius, as a scale that is at 32 degrees on melting point of water (0°C), and 212 degrees on its boiling point (100°C).
Fahrenheit’s hometown is certainly the metric everyone should use /s
Celsius is not arbitrary, it is based on objective physical reality, and the only arbitrary thing about it is atmospheric pressure, which is more or less equal on the sea level. The rest is us finding convenient patterns, not the other way around. 0-40 is not a scale, it’s an arbitrary range and adaptation of Celsius to subjective feelings of hot and cold - one that you ironically need for Fahrenheit, too. Actual thermometers normally go -50°C to +50°C.
On sub-zero, it is the same idea: -5°C is a weather for a light winter jacket, -15°C is a weather for a heavy winter jacket, -25°C is for heavy jacket and some pullover, etc etc.
The 0-40 argument demonstrates that we don’t need some arbitrary scale based on Fahrenheit’s recording in his hometown in order to conveniently estimate temperature. The groups for each dozen of degrees are just for easy reference. 17 degrees is optional for your taste, to me it’s light jacket weather in overcast or t-shirt weather when sunny. There are no perfect temperatures for anything and anyone, and it just doesn’t make sense to get into more detail.
As per granularity, people invented decimals, but normally it’s simply not necessary to tell the difference between 17°C and 18°C, let alone between 63°F and 64°F. There are so many factors influencing the temperature feeling, and one degree ain’t one.
Then you map it onto Celsius and see 32°F is 0°C, 71°F is 21,7°C and 100°F is 37,8°C.
Which coincides almost perfectly with the 0-20-40 framework we intuitively use in Celsius. 0 is deadly cold without warm clothes, 20 is warm, and 40 is deadly hot.
Turns out Celsius is good for weather, too. or it’s illuminati
What makes 0°F (-17,7°C) special for a human body? Is it the limit after which we don’t feel any colder? No.
And what makes 100°F (37,7°C) special? Maybe we can’t feel any hotter? No, we can. Is it the body temperature? No. What is it?
Maybe 50°F (10°C) is perfect? Nah, cold!
If we change 0°F to, say, 0°C and 100°F to 40°C, does it change the notion that 0°F is very cold for a human body and that 100°F is very hot? No, and as a bonus you get 50°F equaling that perfect 20°C.
Fahrenheit scale is super arbitrary and it’s hilarious when it is posed as a “human-centric” scale. At the same time, the concept of Fahrenheit scale is unnecessarily complicated and the notion between Celsius is extremely clear - you can easily calibrate Celsius thermometer with nothing but kettle and freezer, right at home, right now.
Total war is not just an abstract political move, it’s an immense suffering and deaths of dozens of thousands of civilians.
It’s easy to play political mastermind from the safety and comfort of your home. People who witnessed war know full well what it entails, and they know it’s not just numbers and maps and politics.
It’s blood. It’s broken families. It’s famine. It’s the destruction of everything they valued. It’s PTSD for just about everyone who managed to survive.
Think twice before saying things like that. Please.
Well, it’s obviously dictated by hardware and the software that manufacturers release for it. I’m not calling enthusiasts to reverse engineer every single driver, that’s impossible.
The point is, there is a lot of proprietary blobs in everyone’s systems, and it’s not cool. If you ask me, we should obviously shift policies to force manufacturers to open source drivers and management systems.
