In my (German-made) car the temperature can be toggled up/down by one degree Fahrenheit. If I switch it to Celsius, an additional digit is displayed which shows either a 0 or 5 that lets me select the temperature in 0.5C degree increments.
To me, this is a pretty clear indication that people can feel the difference in half degrees Celsius (otherwise, why would the manufacturer bother with it?). And because of that, Fahrenheit is better for human-scale temperatures, as only two significant digits are required instead of three.
- yongjik 8y agoPeople can feel the difference between a particular air conditioner blowing cool air at intensity 3 versus intensity 4, which is what these "temperature" dials boil down to. That doesn't necessarily mean that they can distinguish two identical rooms with 0.5°C temperature difference.
- CompuHacker 8y agoFahrenheit and Celsius have a thing where one degree in Celsius equals about two degrees in Fahrenheit. I think your car computer prefers Fahrenheit and misrepresents the exact values.
