Can you feel a difference of 1 degree Fahrenheit? Does it change your behavior? Do you need an extra sweater because it is 57 degrees inside instead of 58? As someone who has grown up with it, I would argue that the Fahrenheit system is too granular.

In general, if I ask someone what the temperature is, it will be estimated as "low 70s" or "high 50s". Never have I met anyone who would feel the temperature and then declare that it is 72 degrees, as opposed to 71 or 73. This suggests that the granularity is greater than what people feel, and is unnecessary for day-to-day use.
