The math and prefix conversion is intuitive (because most of the world uses base-10 these days). There is nothing particularly intuitive or handy for either of them with respect to temperature - you just learn what it means and work with it. I've been using metric since I was 6, so like a good Canadian weather is metric and baking is Fahrenheit. When I talk about combustion points, melting points of metals, boiling point of water, back to metric. See? Intuitive.
