Thermostat 1 does not correspond to 100°C, but to 30°C less than this commonly accepted value. The majority of old French recipes still apply this convention, inherited from the first household ovens, while most modern appliances display the temperature directly in degrees Celsius.
Inaccuracies persist among manufacturers, with some rounding to the nearest ten, while others maintain a graduation in increments of 30°C. Despite the widespread use of digital displays, these discrepancies continue to affect cooking success. A rigorous conversion helps avoid mistakes and properly adjust settings.

Why do thermostats 1, 2, and 3 cause confusion in the kitchen?
Forget the simplicity of round numbers: the conversion between thermostat and degrees Celsius is no child’s play. The first domestic ovens only displayed a simple number. Today, recipes inherited from that time still carry this habit, without always providing a clear equivalence.
Between the vagueness of manuals, unclear thermostats, and the variety of models, it is impossible to find your way without a minimum of vigilance. Each manufacturer has defined its own scale, and the transition from one notch to another is not always consistent. Sometimes it is believed to be a regular progression, while the reality is more nuanced.

Faced with a thermostat 1, 2, or 3, doubt creeps into the kitchen. Is it a difference of 30°C? 40°C? A simple symbol? Recipe books differ, as does the oven display. Yet, a difference of just a few degrees is enough to change the texture of a cookie or the lightness of a soufflé.
To clarify the ambiguity, there is a reliable resource: discover the equivalence of thermostat 1 2 3 in degrees on the dedicated page: Thermostat 1, 2 and 3 in degrees: equivalence – Beynat. Familiarizing yourself with the actual temperature of the oven gives you every chance of successfully baking a golden bread, an airy cake, or perfectly controlled low-temperature cooking.
Here is an overview of the temperature ranges associated with each thermostat, to clarify things:
- Thermostat 1: around 30°C to 40°C, ideal for preparations that require very gentle heat.
- Thermostat 2: about 60°C to 70°C, perfect for meringues or melting chocolate safely.
- Thermostat 3: between 90°C and 100°C, the realm of slow cooking and delicate desserts.
Navigating between thermostats and degrees Celsius therefore requires attention and adaptation. Old recipes and modern ovens do not always speak the same language. Relying on a reliable conversion is to regain the precision that makes all the difference in the kitchen.
Practical table: precise equivalences between thermostats and degrees Celsius
To put an end to uncertainties and have a clear reference, here is a summary table that outlines the correspondence between each thermostat number and the temperature in degrees Celsius. This guide allows you to adjust each oven setting with confidence, to succeed in all cooking, even the most delicate.
| Thermostat | Degrees Celsius |
|---|---|
| 1 | 30 to 40 °C |
| 2 | 60 to 70 °C |
| 3 | 90 to 100 °C |
This conversion table simplifies the preparation of all recipes. Both professionals and amateurs can rely on these values to adjust the oven temperature at each stage. To go further, the dedicated page on the equivalences of thermostat 1 2 3 in degrees offers additional references to consult according to the needs of each cooking.

Tips for adjusting your oven temperature and succeeding in all your recipes
The success of a dish sometimes hinges on just a few degrees. Between traditional thermostats and digital displays, the actual temperature of the oven may differ from what is indicated. To avoid unpleasant surprises, it is better to equip yourself with a reliable oven thermometer. This small tool makes all the difference: it reveals invisible discrepancies, even in the most recent appliances.
Consider the nature of each preparation. A choux pastry requires a well-heated oven, around 180 °C (thermostat 6), while a meringue prefers the gentleness of a thermostat 1, or 30 to 40 °C. Each dish has its requirements, and mastering the adjustment ensures the expected result.
Some simple gestures can optimize cooking:
- Always remember to preheat your oven. A stable temperature guarantees an even rise in heat.
- Avoid opening the door during cooking: each opening lowers the thermostat, directly impacting the result.
- Place your dishes in the center of the oven. This is where the heat distributes best, with no overly hot or cold zones.
Also observe the color and texture of your preparations. If the surface browns too quickly, reduce the temperature by a few degrees. For long, gentle cooking, such as confits or terrines, carefully adjust the thermostat to maintain a steady heat.
Thermostats 1, 2, and 3 are often chosen for slow cooking, defrosting, or keeping warm. This precise setting allows for soft textures, preserved aromas, and perfectly controlled cooking. Taking the time to adjust the internal temperature of the oven gives you the freedom to experiment and refine each dish, far from the simple automation of conversion.
Ultimately, the right temperature opens the door to an infinite number of culinary successes. A well-adjusted oven promises a melting cookie, a singing bread, and a dessert that never betrays the original recipe.
