455°F converts to Gas Mark 8 in UK ovens and air fryers. This high temperature is ideal for roasting meats, baking pizzas, or achieving crispy textures in your air fryer. At airfryerrecipe.co.uk, we often use this temperature for quick, restaurant-quality results with minimal oil.
The Gas Mark scale is a British measurement system for oven temperatures, ranging from Gas Mark ¼ to Gas Mark 9. 455 F to Gas Mark conversion gives you Gas Mark 8, which sits at the higher end of the scale. This makes it perfect for dishes that need a strong initial heat like Yorkshire puddings or flaky pastries. Many air fryer recipes adapted from traditional oven cooking will reference both Fahrenheit and Gas Mark temperatures. Our air fryer conversion chart helps bridge these measurement systems effortlessly.
When converting 455 degrees Fahrenheit to Gas Mark, remember that each Gas Mark represents about 25-30°C (45-50°F). Gas Mark 8 specifically corresponds to 455°F (235°C) in most standard conversion tables. This consistency means you can confidently use 455 F in Gas Mark recipes whether you're using a conventional oven or modern air fryer. The key difference comes in cooking times - air fryers typically cook faster at the same temperature.
This temperature hits the sweet spot for many cooking techniques. The high heat creates excellent Maillard reaction (browning) while keeping cooking times reasonable. For air fryer users, 455 F to Gas Mark conversion means you can follow traditional British recipes with precision. Try it for chicken recipes where you want crispy skin and juicy meat simultaneously.
When using 455 F in Gas Mark equivalent for air frying, reduce cooking times by about 20% compared to oven instructions. The concentrated heat circulation in air fryers means foods cook faster and more evenly at this temperature. For example, roasted potatoes that take 40 minutes in a Gas Mark 8 oven might only need 30-32 minutes in an air fryer at 455°F. Always check your food a few minutes early when first trying a new recipe.
Another key adjustment is reducing oil quantities. Where a Gas Mark 8 oven recipe might call for 2 tablespoons of oil, your air fryer version at 455 F may only need 1 teaspoon. The rapid air circulation ensures crispiness without excess fat. This makes our potato recipes particularly successful at this temperature conversion.
Several dishes shine at this temperature conversion. Pizza achieves perfect crispiness at 455 F to Gas Mark 8 in just 8-10 minutes in an air fryer. Roast chicken benefits from starting at this high heat before reducing temperature. Even baked goods like scones develop excellent rise and colour when using the 455 degrees F to Gas Mark conversion.

When cooking at 455 F (Gas Mark 8 equivalent) in your air fryer, always ensure proper ventilation. The high heat can generate more smoke than lower temperatures, especially with fatty foods. Keep your air fryer at least 10cm away from walls and other appliances. Regular cleaning is crucial - built-up grease can smoke at these temperatures. Use our guide on air fryer cleaning to maintain your appliance.
Another safety consideration is cookware materials. At 455 F to Gas Mark 8 temperatures, some plastics or thin baking papers may not be suitable. Always use air fryer-safe accessories rated for high heat. The intense air circulation can dislodge lightweight papers, potentially causing burning or fire hazards. Metal baskets or perforated pans work best for consistent results at this temperature conversion.
