Nobody even uses exact degrees when using Fahrenheit and talking about the weather. You can’t feel the difference between 71 and 72. Most people just round off to the nearest 5 degrees or so when talking about the weather. With Celsius you might be slightly more likely to use a non-rounded value, say 22 degrees instead of 20 or 25. But, you’re almost never going to use fractional degrees.
