It is, but if you look at how Farenheit was conceived it’s absurdly nonsensical. 0°F is the freezing temperature or some mixture of chemicals, and 90°F is a guess at human body temperature lmao.
And the freezing/boiling points of water are arbitrary except in that they are used to actually define both scales. They provide easily measurable standards.
Well TECHNICALLY it’s not based on the state change of water.
It’s based on the formula C = K - 273.15 where K = 1.380649×10^−23 / (6.62607015×10^−34)(9192631770) * h * Δν[Cs] / k where k is the Boltzmann constant (1.380649×10^−23 J * K^-1), h is the Planck constant, and Δν[Cs] is the hyperfine transition frequency of Caesium
Every scale and unit is, ultimately, arbitrary. We all do have a very good understanding of what freezing and boiling water is, though, we don’t have a good intuition of “coldest day in some random place in some random year” is. Then there’s a couple of other common points of orientation: 20C is room temperature, 37C body temperature and thus warm baths and “it’s too bloody hot outside” hover around that (you actually want wet-bulb temperature for that, but it’s still a point of orientation), another point is about 60C which is the hottest you can have a beverage and drink it without excessive slurping. Also a common temperature in cooking as that’s when a lot of stuff starts to denature, e.g. egg white is about 62-65C, the temperature you want to hit for carbonara to not get scrambled eggs.
Practically everything we deal with in everyday life (short of winter weather) is within that 0-100 range. Which is due, to, well, water being liquid in that range.
Isn’t basing a temperature scale on the freezing and boiling points of water a bit arbitrary in and of itself?
The reason they are arbitrary numbers in Fahrenheit is because they weren’t considerations when the scale was made.
Water is everywhere.
Cooking, weather, etc. You are also water.

So even MORE abstract and unrelatable
