339 F converts to approximately 170 C in a fan oven. This is the standard UK equivalent for convection cooking, whether you're using a traditional fan-assisted oven or an air fryer. The conversion is crucial for achieving perfect results with recipes originally designed for conventional ovens. At airfryerrecipe.co.uk, we specialise in helping you adapt any recipe for modern cooking methods.
Understanding 339 F in fan oven cooking
When converting 339 F to fan oven settings, you're dealing with a moderate baking temperature ideal for many dishes. Fan ovens circulate hot air, cooking food more evenly and often faster than conventional ovens. This 339 F (170 C) setting works beautifully for roasting vegetables, baking cookies, or preparing chicken thighs in your air fryer. Many of our popular recipes use this temperature range for balanced cooking.
The 339 F to fan oven conversion becomes particularly important when following American recipes in UK kitchens. Since most British ovens use Celsius and fan settings, knowing this equivalent prevents under or overcooking. For air fryers, which essentially work like mini fan ovens, this 170 C setting delivers crispy results without burning. Check our conversion chart for other common temperature adjustments.
Why 339 F matters in air fryers
Air fryers typically operate at higher fan speeds than conventional fan ovens, meaning the 339 F (170 C) setting might cook food slightly faster. This temperature works perfectly for chicken recipes, giving crispy skin while keeping meat juicy. It's also ideal for reheating leftovers or cooking frozen foods evenly without drying them out.
Converting other temperatures around 339 F
When working with temperatures close to 339 F, the conversion principles remain the same. For example, 350 F converts to 180 C in a fan oven, while 325 F becomes 160 C. These slight variations matter when baking sensitive items like cakes or pastries in your air fryer. Our temperature guides help you navigate these small but crucial differences for perfect results every time.
Many air fryer models have preset functions that automatically adjust cooking times for different temperatures. However, understanding the 339 F to fan oven conversion gives you more control over custom recipes. This knowledge lets you adapt family favourites or experiment with new dishes confidently.

Common uses for 339 F in air fryers
The 339 F (170 C) setting shines when cooking thicker cuts of meat or dense vegetables in your air fryer. It provides enough heat to crisp the exterior while gently cooking the interior. This temperature also works well for baking items like scones or biscuits that need even browning without burning. For potato dishes, it creates perfect roasties with fluffy interiors and crispy skins.
Tips for perfect 339 F air fryer cooking
When using the 339 F fan oven equivalent in your air fryer, always preheat for 3-5 minutes for consistent results. Shake or turn food halfway through cooking to ensure even browning at this temperature. Reduce cooking times by 20% compared to conventional oven recipes, checking for doneness a few minutes early. These adjustments account for the air fryer's efficient circulation of hot air.
Remember that different air fryer models may vary slightly in how they maintain the 339 F equivalent temperature. Smaller baskets might cook faster, while larger models could need slight time adjustments. Keep a cooking journal to note what works best with your specific appliance at this temperature setting.
