Counterpoint to #1, celsius increments are too large. I laugh every time I see a thermostat in a car or home that needs to have steps like 20, 20.5, 21, 21.5..

Do you honestly notice the difference in comfort between 20°C and 20.5°C? I suspect even the heating element is not that precise, let alone the actual room temperature. They only case in daily practice where 1°C is too large is the difference between normal body temperature (36.5°C) and mild fever (37.0°C), but thermometers have to be graduated in much smaller subdivisions anyway.

  > Do you honestly notice the difference in comfort between 20°C and 20.5°C? Yeah, it's noticeable. That 0.5C move is roughly a 1F move. And there's definitely a noticeable difference between 71F, 72F, and 73F. But I'd say that it ultimately only matters in human comfort and only when you are talking about room temps. Once you get outside that 70->75 range the exactness starts mattering a lot less. 80 and 85 both feel hot. 65 and 60 both feel cold.

I mean, it's arbitrary. I've lived in a Fahrenheit country and a Celsius country and both systems work fine. Resolution issues exist for both systems (you can still benefit from decimals in Fahrenheit for coffee and tea brewing) I prefer Fahrenheit because it's based around the human, but it really doesn't matter, and it's probably better long term to have measurements that are not based around the human condition, but we're talking about benefits to society tens of thousands of years from now, rather than today.

How is that a counterpoint to #1? By that same logic, inches are too big an increment so it's hilarious every time fraction of one is used. 15/16ths? lololol!

  I agree with your logic, and this is a good reason to use centimeters instead of inches.
