193 C converts to approximately 170 C in a fan oven. This 20-25 degree reduction is standard when adapting conventional oven recipes for fan-assisted cooking. Whether you're using an air fryer or traditional fan oven, this conversion ensures your food cooks evenly without drying out.
Fan ovens circulate hot air constantly, cooking food faster and more evenly than conventional ovens. This means you'll need to reduce the temperature by about 20 degrees when converting from Celsius to fan oven settings. Our air fryer conversion chart makes these adjustments simple for all your favourite recipes.
When working with 193 C specifically, lowering it to 170 C in a fan oven prevents overcooking. This is particularly important for delicate bakes like cakes or pastries where precise temperature control matters. Many modern air fryers function similarly to fan ovens, making this conversion equally relevant for air fryer cooking.
The forced air circulation in fan ovens and air fryers increases heat transfer efficiency. At 193 C in a conventional oven, heat reaches food more gradually. The same temperature in a fan setting would cook the exterior too quickly before the interior is done. That's why we recommend 170 C for fan ovens when a recipe calls for 193 C.
Most air fryers operate on similar principles to fan ovens, with rapid air circulation being their defining feature. When you see 193 C in a recipe, set your air fryer to 170 C for equivalent results. Check out our recipe collection for specially adapted air fryer versions of classic dishes.
Remember that cooking times may also need reducing by 10-15% when using fan settings. A cake that takes 30 minutes at 193 C in a conventional oven might only need 25-27 minutes at 170 C in a fan oven or air fryer. Always check food a few minutes early when trying new conversions.
While the 193 C to 170 C conversion works well for most foods, some items need slight adjustments. Dense foods like roast potatoes might benefit from keeping closer to 180 C in a fan oven. Conversely, delicate items like meringues might need dropping to 160 C. Experience will help you fine-tune these conversions.
One frequent error is forgetting to adjust both temperature and time. Converting 193 C to 170 C in a fan oven isn't enough - you must also reduce cooking duration. Another pitfall is assuming all ovens are identical - always verify temperatures with an oven thermometer, especially when trying new conversions.
Using the wrong cookware can also affect results. In air fryers and fan ovens, shallow pans work better than deep dishes for even cooking. Our guide to maintaining your air fryer includes tips on choosing the right accessories for perfect results every time.
For quick reference, keep a temperature conversion chart handy in your kitchen. Alongside the 193 C to 170 C fan oven conversion, you'll find other common equivalents. Many modern air fryers include conversion settings, but it's still helpful to understand the principles behind the adjustments.
When converting 193 C recipes for fan ovens or air fryers, start checking for doneness 5-10 minutes before the original recipe suggests. Rotate or shake food halfway through cooking when possible - this ensures even browning in the circulating air environment. For chicken dishes and other proteins, use a meat thermometer to confirm safe internal temperatures.
Remember that altitude and humidity can affect cooking times too. If you're adapting a 193 C recipe from another source, consider these environmental factors along with the fan oven conversion. With practice, you'll develop an instinct for perfect temperature adjustments.
