179°C in a fan oven equals approximately 160°C in a conventional oven. This conversion is essential for adapting recipes between different oven types, especially when using an air fryer which often follows fan oven principles. At airfryerrecipe.co.uk, we know precise temperature conversion makes all the difference in cooking results.
Understanding Fan Oven vs Conventional Oven Temperatures
Fan ovens circulate hot air using a fan, cooking food faster and more evenly than conventional ovens. When a recipe calls for 179 fan oven, it's specifically designed for this efficient heat distribution system. The general rule for conversion is to reduce the temperature by 20°C when moving from fan to conventional ovens.
This 20°C reduction accounts for the concentrated heat in fan-assisted cooking. For example, our air fryer conversion chart shows similar adjustments when switching between appliances. Many modern recipes, especially those at cake recipes, now specify fan oven temperatures as standard.
Why 179°C Fan Oven is Common
179°C fan oven (160°C conventional) is a popular temperature for baking and roasting. It's hot enough to crisp surfaces while gently cooking interiors - perfect for everything from Victoria sponges to roasted vegetables. This temperature also prevents burning while ensuring thorough cooking.
Practical Conversion Examples
Let's examine specific cases where converting 179 fan oven to conventional oven matters. When baking cookies at 179°C fan, you'd set your conventional oven to 160°C. The same applies for roasting chicken - though cooking times may vary slightly due to different heat distribution.
Our testing shows that air fryers set to 179°C produce similar results to fan ovens at this temperature. For frozen foods like those in our frozen food section, this conversion ensures proper cooking without over-drying. Always check food 5-10 minutes before the recipe's suggested time.
Adjusting Cooking Times
While temperature conversion is straightforward, cooking times may need adjustment. Conventional ovens at 160°C typically require 10-15% longer cooking than fan ovens at 179°C. Monitor your food's progress rather than relying solely on timers.
Special Considerations for Air Fryers
Air fryers essentially work like compact fan ovens, making 179°C a common setting. However, their smaller capacity means food cooks faster. When converting conventional oven recipes to air fryer, use the original fan oven temperature (179°C) but reduce cooking time by 20%.
For cleaning after high-temperature cooking, our air fryer cleaner guide offers helpful tips. Remember that while 179 fan oven to conventional oven conversion is simple, each appliance has unique characteristics that affect results.
Temperature Accuracy Matters
Oven thermostats can vary, so consider using an independent oven thermometer. If your conventional oven runs hot, you might need to reduce the 160°C setting further. Conversely, underperforming ovens may require slight increases for proper cooking.
Converting Other Common Fan Oven Temperatures
The same 20°C reduction principle applies across temperature ranges. For example, 200°C fan becomes 180°C conventional, while 150°C fan converts to 130°C conventional. This consistency makes adapting recipes straightforward once you understand the basic conversion.
When exploring air fryer recipes, you'll notice many specify fan oven temperatures. The 179 fan oven to conventional oven conversion is just one example of how understanding these differences improves your cooking across all appliances.
Historical Context of Oven Temperatures
The move toward fan ovens began in the 1970s as energy-efficient alternatives. Today, about 80% of UK households use fan ovens, making temperature conversion knowledge essential for sharing and adapting recipes between different kitchen setups.
