I've lived in the USA my whole life. I've decided to teach myself to think in Celsius instead of Fahrenheit when it comes to the weather. Of course we had to use it in school for classes like Chemistry but I've never needed it day to day. I've switched my phone and our home indoor/outdoor weather center. We'll see how it goes. 30 is hot 🥵, 20 is nice 😊, 10 is cool 😐, 0 is ice 🥶. Old dog, new tricks.
