Except when water doesnt boil or freeze at 0/100; Based off altitude or salinity and some other things. You dont need a whole temperature scale based off those 2 factors. Water will boil when it bubbles on the stove, and will freeze when it turns solid in the freezer. Kelvin is better for scientific numbering. Fahrenheit is better for daily life.

I will admit, distance and volume measuring is better metric. I’m so sick of having to play the math game of teaspoons to tablespoons to cups etc. Distance is easier too once you use it for a while. I bet you could ask a ton of people how far a mile is, and many wouldnt be able to give you distance in feet…
