For your convenience I have translated this to the PopTart scale:

    1 = cold PopTart
    2 = cold PopTart
    3 = slightly above room temperature PopTart
    3,49999999 = tepid PopTart
    3,5 = Nicely done PopTart *
    3,50000001 = House fire
    4 = Magma
    5 = Plasma
    6 = Self-sustaining nuclear fusion

    * theoretical outcome never actually observed
