I've heard this argument many time and personally do not understand. The ambient temperature is such a subjective thing, so many things affect it besides absolute temperature: wind, sunlight, humidity. And it changes so fast too. I don't think I even need the precision of Celsius, I don't get the necessity of twice the precision of Fahrenheit. And sure, cmiller1, the reference points are arbitrary in Celsius, so are they in Fahrenheit. At least in Celsius the zero point could provide useful information: I know when it's slightly higher than 0˚C there would be mud, when lower — icy roads. (And it isn't really affected by the elevation — ~0.01˚C in the whole range of liveable pressures.) But that's, I believe, irrelevant: I have intuitive understanding of -17˚C or 37˚C without it being a round number, the same way you know what's 32˚F.
