189 C converts to approximately 170 C in a fan oven. This is because fan ovens circulate hot air, allowing you to reduce the temperature by around 10-20% for even cooking. Whether you're baking a cake or roasting vegetables, this conversion ensures your dishes come out perfectly every time.
Fan ovens cook food more efficiently than conventional ovens, thanks to their built-in fans that distribute heat evenly. When a recipe calls for 189 C, it’s usually designed for a traditional oven. Converting 189 C to fan oven settings (around 170 C) prevents overcooking and ensures your food is evenly baked. This is especially useful for air fryers, which work similarly to fan ovens.
If you’re using an air fryer, you might wonder how 189 C translates. Most air fryers operate like mini fan ovens, so the same rule applies. For example, if a recipe suggests 189 C in a conventional oven, set your air fryer to 170 C. You can find more tips on our air fryer conversion chart.
Reducing the temperature isn’t the only adjustment you might need. Cooking times can also vary when converting 189 C to fan oven settings. Since fan ovens cook faster, you may need to shorten the cooking time by 5-10 minutes. Keep an eye on your food, especially when trying a new recipe.
For air fryers, the cooking time might be even shorter. A dish that takes 30 minutes at 189 C in a conventional oven could be done in 20-25 minutes at 170 C in an air fryer. Check out our recipe collection for tested air fryer adaptations.
Many recipes, especially baked goods, call for 189 C. Here are a few examples where converting to 170 C in a fan oven works perfectly:

When using 189 C in a fan oven or air fryer, a few extra tips can make all the difference. Always preheat your appliance to ensure even cooking from the start. Use a light-coloured baking tray to prevent over-browning, and rotate your food halfway through if needed.
Cleaning your air fryer after each use is also crucial for maintaining performance. Our guide on how to clean an air fryer makes it quick and easy.
While both appliances use circulating hot air, air fryers are more compact and cook faster. If a recipe suggests 189 C in a fan oven, you might need to reduce the temperature further in an air fryer. Experiment with 160-165 C for the best results, especially with smaller portions.
