Oviously it does not work the way it should (by simply chosing °C in the unit box) so one crude way is to do the conversion manually. Not very satisfying, I guess.

The Kelvin and Rankine scales are absolute--they both start at absolute zero and are therefore a ratio.  Centigrade (Celsius) and Fahrenheit scales have arbitrary (and different) zero reference points.  Mathcad has to use functions for that conversion.  If you look under units the the ribbon, you can select which units to plot with.
