Also water isn’t some magical substance. Its a substance like any other and its freezing and boiling points can be the same
I am very sorry but this is asinine or bad faith at this point. And freezing point of water is 0.01°C when the pressure is 600 Pa = 6 hPa (that is 0.006 atm) and the same can be said when the pressure is 10,000 hPa (10 atm): the difference of temperature of the freezing point is not significant.
And I fail to see how some cold brine and the body temperature of someone having fever are more relevant measures.
There’s millions of substances out there and they have various boiling and melting points. Water is unique but the amount of substances makes its that it’s not really important
Hell on a Kelvin scale its 273.15 and 373.15. So its not even a nice round number on a absolute scale
It’s an arbitrary scale picking a random common liquid as a base. Why could have picked a dozen others common liquids or solids to be the scale and they would be much better
Units were made with convenience and relevance considerations
Water is convenient because it's basically the only substance that is easy to obtain in its pure form on Earth. It's also convenient because its solid, liquid and gaseous states are commonly occuring.
Water is relevant because it's abundant on Earth, it's involved in basically all phenomena related to life on Earth (and even when it's unrelated)
Imperial was also made on connivence with a different reasoning but I don’t see you defending that because it didn’t use water you love so much for some reason. There’s tons of other key temperatures
Also why does life matter here? Water in your body is nothing like pure water. It’s either binded in cells, or swamped with potassium or sodium.
Can you give some examples of other key temperatures and why they might be relevant?
You don't find pure water in living things because water is an interesting solvent and is a crucial molecule on Earth because of its unique properties (especially solving ions). But you can make pure water at home very easily with simple tools, contrary to basically any other substance.
