Depending on the recipe you are following, the cooking temperature is indicated either in degrees Celsius or by the number of the oven thermostat. To avoid asking each time the question of what exact temperature it is, we offer you the elements to know to convert without error the degrees Celsius into the thermostat number and vice versa, according to the recommended heat of the oven. .
Each thermostat number corresponds to an additional 30°C temperature. No.1:30°C, No.2:60°C, No.3:90°C, etc. To convert the thermostat number to a degree, simply multiply it by 30 (for example, thermostat n°6 =6x30, i.e. 180°C).
Conversely, if a recipe tells you a temperature in degrees and you want to know which thermostat it corresponds to, you must divide this temperature by 30. For example, for a temperature of 120°C:120/30 =4 ( thermostat number).
