° shouldn't be used with Kelvin scale.

  You are right, I forgot. In the sixties the "Kelvin" became a Unit of Measure. But it's a convention - it remains a "degree", somehow, though the concept is weak: it indicates discreets, values are continuous. Degrees make more sense when "24.4" does not, while measurements are intended to be ideally precise.
