In metric world nobody cares about decimal points in temperature outside. Measuring precision is not that good because of wind, humidity, exposure to sun etc. We just don’t need that granularity, so it is really hard to understand why would you need that. Is there really any difference between 56°F and 57°F that you can feel and want to measure?

And choice of 0/100 for weather is absolutely baseless. You do have below-zero days and in some places it can be over 100. With Celsius you know when it’s going to be ice on the roads and when rain becomes snow.

below zero days are really really crazy cold and above 100 days are really really crazy hot. I don't think the fact that things occasionally exceed the 100 point "normal" range makes it less useful, if anything the out of bounds numbers emphasize the severity of the temperature. it's common where I grew up in the midwest US to hear "wow its going to be BELOW ZERO" as a way to express extreme cold

For me personally “really really cold” starts below -30°C and crazy hot is above +30°C. It’s very subjective and outside of US many areas have climate where Fahrenheit doesn’t make sense at all.

maybe that's why its popular in the US? for most of this country the 0-100 range works quite well to describe the normal range of outdoor temperature. we seem to like 0-100 ranges, for instance speed in MPH works out nicely.. "over 100 MPH!" is a common expression for extreme speed drivers. school grades are often a value out of 100, etc. which makes you wonder why we don't prefer metric lol
