alt Hacker NewsIs it really better for day to day life? I am certain that it only appears so because you're used to it. I think for day to day life they're both roughly equivalent.
Of course, for me Celsius is more natural and intuitive, but again - that's because I'm used to it.

It's just how some Americans justify this particular measurement system.
As you said: it's what you're used to. I know 100F is a very warm day, but if someone said it was 50F I wouldn't intrinsically know how warm or cold that is. My brain works in Celsius, so someone saying its 20C I understand instantly.
Similarly length in US football fields - I don't know what that is, but it's second nature to someone who did grow up using them as a measurement.
100F is about peak summer heat; 0F is about peak winter chills. Works great for describing weather .. in various places.
You can basically put a "%" after a fahrenheit temperature and read it as "percentage of a really hot day" and you'll get a pretty good idea what it feels like outside.
It's pretty well calibrated as a 0-100 scale for human temperature perception.
