I should add the caveat *in the United States. It would obviously be a pretty dumb comparison for Singapore or Reykjavík. I'd also add that the 10s in Fahrenheit also make nice comfort delimiters. 20 is frigid, 30 is ~freezing, 40 is cold, 50 is cool, 60 is warm, 70 is room temp, 80 is hot, 90 is excessively hot, 100 is oppressive. Again, obviously you can do the same thing with the 5s in Celsius but it does work nicely for the average person. I'm not really saying this is better than Celsius, just that it's understandable why it's not changing as quickly as some would like. I will say that the industries that have specific reason switched fairly quickly. For instance, aviation uses feet, inHg, statute+nautical miles but does temperature in Celsius because pilots overwhelmingly care about whether it's above or below freezing outside.
