464°F converts to Gas Mark 9 in UK ovens and air fryers. This high temperature is typically used for professional baking, pizza cooking, or creating perfect crusts on bread and pastries. When using an air fryer, you might need to adjust cooking times slightly as the rapid air circulation can cook food faster than conventional ovens. Many modern air fryers allow you to switch between Fahrenheit and Gas Mark settings, making it easier to follow traditional recipes. At airfryerrecipe.co.uk, we recommend checking your appliance manual for specific temperature conversion guidelines.
The Gas Mark system is uniquely British, with temperatures ranging from Gas Mark 1/4 (107°C) up to Gas Mark 9 (246°C or 475°F). When converting 464 F to Gas Mark, it's worth noting this falls just below the maximum standard domestic oven temperature. This intense heat is perfect for achieving restaurant-quality results in homemade pizza or artisan bread. If you're adapting a 464 F recipe for your air fryer, consider reducing the cooking time by 15-20% while maintaining the same temperature. Our air fryer conversion chart provides detailed adjustments for various cooking scenarios.
464 F (Gas Mark 9) creates the ideal environment for Maillard reactions - the chemical process that gives baked goods their appealing brown colour and complex flavours. This temperature is particularly effective for foods that benefit from quick, intense heat like puff pastry, vol-au-vents, or certain types of biscuits. In air fryers, the circulating heat at 464 F can produce exceptionally crispy results without excessive oil. However, always preheat your air fryer for 3-5 minutes when cooking at this high temperature to ensure consistent results.
Many professional baking recipes call for 464 F (Gas Mark 9), especially those requiring rapid oven spring and crust formation. When using this temperature in an air fryer, you'll achieve similar results to conventional ovens but often in less time. Popular applications include making baguettes, crispbreads, or even reheating certain takeaway foods to restore their original texture. The team at airfryerrecipe.co.uk/recipes has developed several air fryer adaptations for high-temperature baking that maintain authenticity while optimising for smaller appliances.
It's important to monitor food closely when cooking at 464 F in an air fryer, as the compact space and powerful heating elements can lead to quicker browning. For items like homemade pizza, we recommend checking every 3-4 minutes to prevent burning. Using perforated parchment paper or specially designed air fryer liners (available at our cleaning section) can help prevent sticking while allowing proper air circulation at these high temperatures.
When operating any appliance at 464 F (Gas Mark 9), safety should be your priority. Always use oven mitts when handling the air fryer basket, as the metal components can become extremely hot. Ensure there's adequate clearance around your air fryer - at least 5 inches on all sides - to allow proper ventilation. Avoid overcrowding the basket when cooking at this temperature, as it can lead to uneven cooking and potential smoke generation. Regularly cleaning your air fryer (especially after high-temperature use) prevents oil buildup that could smoke at these intense heats.
The conversion between 464 F and Gas Mark 9 is straightforward, but understanding the context matters. While 464 F technically equals Gas Mark 9, some ovens may have slight variations in actual temperature. Using an oven thermometer can help verify your appliance's accuracy, especially important for baking where precision matters. In air fryers, the temperature sensors are typically very accurate, but the rapid air movement means you might need to adjust cooking times rather than temperatures when converting recipes.
For those frequently converting between Fahrenheit and Gas Mark, creating a reference chart can be helpful. Alongside our standard 464 F to Gas Mark conversion, you might want to note nearby temperatures like 450 F (Gas Mark 8) or 475 F (between Gas Mark 9 and 10). These references become particularly useful when adapting recipes from American cookbooks or websites to UK measurements.

If your air fryer doesn't reach 464 F (Gas Mark 9), there are still ways to achieve similar results. Many air fryers max out around 200°C (392°F), but you can compensate by extending cooking time slightly and using techniques like preheating or finishing under a grill. For dishes requiring the intense heat of 464 F, consider using the air fryer for initial cooking then finishing in a conventional oven if available. This two-stage approach works particularly well for items like sourdough bread or flaky pastries that benefit from the initial high heat blast.
