A:Answer Mine is already set at Fahrenheit but if you were wanting to set it to Celsius I do not know. However, after trying several different ways I have found that for toast you want to use the air fry setting, temperature set at 400 degrees and place the tray you are using on the upper most rack for 2 minutes. If you want it lighter, move the tray to the middle rack. If you want it darker, increase the time to 3 minutes.
