On my Stoves oven the temperature control degrees Centigrade match the rotation in angular degrees.
The knob rotates anticlockwise and the first marking is 100 deg C at just past 90 deg rotation - 180 deg heat is exactly half way round - 280 deg (the maximum) is just past three-quarters rotation.
Yours may be different - or perhaps the same.
Enjoy your Christmas dinner.
