Fahrenheit is too granular, imo. In day to day life I almost always hear people talk about it in ranges of temperature (eg. “mid 70s”) which defeats the point of having a more granular system.

Even in Celsius you often “it’s been 25 and 30” etc. Weather is just not a super accurate thing, it can be different up or down the hill, at the next town over, etc, so I don’t get the granularity argument. Maaaybe I can understand the one about 0 to 100 making sense for weather related temperatures to people used to it, maybe.
