Check the script there man! It can be done even with F temperatures. And the progress bar with that script DOESN'T show the %! Depends on the design (the length of the progress bar) and the values that you want to add. Don't forget that you can create 2 separate layers with C and F. But I'm almost sure that you didn't even check it..
