# Why did my oven temperatures change automatically?

| **Quick answer:** When **Automatic Temperature Conversion** is set to **Auto**, CookBook rewrites any oven temperature in your recipes **°C, °F,** or **Gas Mark** to match the option and fan-setting you’ve chosen. Switch it to **Auto** or **Disabled** in the pop up or **Side menu ☰ → Settings → Conversions → Oven conversion** if you’d rather keep temperatures exactly as written.

# What the automatic temperature conversion does

* Finds temperatures like **180 °C**, **350 °F**, **Gas 4**, or **160 °C fan** inside your recipe steps.
* Converts each one to the target scale you’ve selected (Celsius, Fahrenheit, or Gas Mark).
* Adds or removes the fan-assisted adjustment

**Examples of what you might see**

* Original **180 °C conventional** → shows as **350 °F (fan)** if your settings are Fahrenheit + fan.
* Original **Gas 6** → shows as **200 °C** if your settings are Celsius + conventional.
* Original **375 °F (fan)** → shows as **Gas 5** if your target scale is Gas Mark.

# Change or disable automatic conversion

Open **Side menu ☰ → Settings → Conversions →** **Oven conversion** or open the conversion tool within a recipe by tapping on the highlighted **temperature** **→ Settings cog** and choose:

* **Auto** – CookBook updates temperatures as soon as you view the recipe.
* **Disabled** – Temperatures stay as written until you open the conversion tool to convert a value yourself.
