Down with the metre and litre, claims that the sizes of metric units are unintuitive: "On the other hand, a degree celsius is too large and imprecise. By contrast, the Fahrenheit scale was custom made to measure weather phenomena: it has human scale."
A celsius degree is 1.8 times the size of a Fahrenheit degree.
Do people who claim this seriously think that they can tell the difference between, say, 61 degrees Fahrenheit and 62.8 degrees Fahrenheit? I don't think they could, and so I would claim that even the Celsius degree is small enough for "everyday" purposes. (In weather forecasts given in Fahrenheit one often refers to, say, the "low seventies" or the "mid-sixties" which seems to imply a resolution of about three or four degrees.) I claim that in both scales, one degree is less than the just noticeable difference for atmospheric temperatures, although I can't quickly find out if the people who study this back me up.
(One thing I do like about using the Fahrenheit scale for weather is that almost all weather I experience is between about 0 degrees and 100 degrees. In some tellings of the story, that's said to be deliberate. There is something weird about negative temperatures, but I'm not quite crazy enough to just start stating all temperatures in Kelvins.)
