Again, why is it superior for every day life?

James touched on it, but essentially it maps temperatures we encounter most often over a more useful numeric range.

How often do you encounter 0 Fahrenheit? Growing up, in the winter it gets below 0C and you know there’s going to be ice outside. In the summer it gets to ~50F.

I also really hate when people conflate units like grams and meters with Celsius. The metric system's main value for humans is that things like kilometers scale easily from things like meters. That entire concept doesn't apply to Celsius.

What's special about the "freezing and boiling point of water"? People act like those temperatures are critical values to encode in 0-100 scale. But why?!

Water's kind of important to humans though, so I get that part. Not sure what other thing is better to measure against.

Water might be important but that doesn't necessarily mean "freezing" and "boiling" are good fixed endpoints. I mean nothing's wrong with those but unlike grams and meters Celsius is just not buying us that much.

Freezing and boiling can be directly correlated to weather though which is where temperature is most useful. While the weather is never "boiling", the upper limit can be used as a relative reference.
