It would be great if the US had already converted to metric. Most people agree on that. But the challenge of actually getting through the conversion is non-trivial.
In general, I'm a big fan of metric, and use it preferentially despite growing up mostly in the US. But for temperature specifically, the fact is that Centigrade uses only 2-4 leading digits for the range of temperatures most people experience, while Fahrenheit uses all ten (and a few over). So °C requires you to care about the second digit to have the same information °F gives you in the first.
(To see why this is important, consider the limiting case of simply using Kelvins instead of °C. Same unit size, more rigorously defined base, even harder to mess up conversions — all the great advantages people always talk about for the metric system! — but you have to look at all three digits to see what approximate range you're in… 301 K is a reasonable temperature, and so is 280 K, but 208 K is a whole different story, and 380 K is no fun for anyone.)
The others don't have such a specific advantage, so I don't know that there's any real objective intuitive advantage there.
