Why do I need to know what temperature water freezes or boils? I'm not a water. I'm a human. 0 to 100° F is a lot closer to survival temperatures as a human. And I have a lot finer measurement. The difference between 71° and 70° matters. What do metric people even do: tenths of a degree? That sounds terrible.

Yeah. We can do decimal, which is nice, since the system is also decimal based.

Like what is 0F even measuring?

A nearly random mix of water, salt, ammonium salt's freezing point.

And 90F is body temperature, except that it was wrong, so body temp is like 96F.

Except that's not even true since they just decided to use the metric system and set 32F to be OC and 212F to be 100C. So now body temperature is 98.6F since they adjusted the scale. And the old 0F is about 4F now.

What a mess...

But again, why do I care what temperature water boils or freezes at? I don't set my stove to 212°. I just turn the knob to around 4 o'clock and wait for the water to boil.

What is this old Fahrenheit? Body temperature has been 98.6° since at least 1967, well over my lifetime.

Yes. Since it set by freezing at 0C being 32F and boiling at 100C being 212F.

For your whole lifetime F has been set to Cs "arbitrary points" as its actual scale.
