Gas Mark 9 converts to 246°C, making it one of the hottest settings for ovens and air fryers. This high temperature is perfect for achieving crispy skins on meats, quick baking, or roasting vegetables. If you're using an air fryer, you might need to adjust cooking times slightly compared to a conventional oven. At airfryerrecipe.co.uk, we specialise in helping you adapt traditional recipes for your air fryer.
Gas Mark 9 represents a very high heat setting at 246°C, which air fryers can achieve rapidly thanks to their powerful convection systems. This temperature is excellent for searing meats, creating crispy roast potatoes, or baking puff pastry items. Many air fryer models have pre-set programmes that approximate Gas Mark 9 temperatures, but manual adjustment often yields better results. Our air fryer conversion chart helps bridge the gap between traditional oven settings and air fryer cooking.
When converting Gas Mark 9 to Celsius for air frying, remember that cooking times may be 20-30% shorter than conventional oven recipes. The intense circulating heat of an air fryer cooks food more efficiently, so always check your food a few minutes early. For perfect roasts at this temperature, try our chicken recipes specially adapted for high-heat air frying.
Gas Mark 9 (246°C) is particularly useful for certain air fryer cooking techniques. It's ideal for achieving restaurant-quality crispy chicken wings, creating the perfect Yorkshire puddings, or giving frozen foods like chips an extra crunch. The high heat quickly renders fat from meats while sealing in juices, making it excellent for Sunday roasts. Many bakers also use this temperature for quick bread rolls or puff pastry items that need rapid oven spring.
The Gas Mark scale is a British measurement system for oven temperatures, with Gas Mark 9 being one of the highest regular settings at 246°C. While modern ovens often display both, many traditional recipes still use Gas Marks. When using an air fryer, it's helpful to understand that Gas Mark 9 to Celsius conversion is consistent - always 246°C.

For those frequently converting between measurement systems, bookmarking our conversion chart can save time. Remember that air fryers typically have a maximum temperature around 200-250°C, so Gas Mark 9 (246°C) is near the upper limit for most models. Always consult your air fryer's manual for exact temperature capabilities and safety guidelines.
When cooking at Gas Mark 9 (246°C) in an air fryer, timing adjustments are crucial. As a general rule, reduce cooking times by about 20% compared to conventional oven recipes. For example, if a recipe calls for 30 minutes at Gas Mark 9 in a regular oven, start checking at 24 minutes in your air fryer. The powerful fan circulation cooks food more evenly and quickly, especially for items like our recommended potato recipes that benefit from high heat.
Cooking at Gas Mark 9 (246°C) in your air fryer requires some safety precautions. Always ensure your air fryer is placed on a heat-resistant surface with adequate ventilation. At these high temperatures, oils can smoke quickly, so use high smoke point varieties like rapeseed or avocado oil. Regular cleaning is essential too - built-up grease can become problematic at high heats. Check out our guide to air fryer cleaning for maintaining your appliance at peak performance.
It's also worth noting that not all air fryer accessories are suitable for Gas Mark 9 temperatures. Silicone or paper liners might not withstand 246°C consistently, so check manufacturer guidelines. When cooking at this heat, use metal baskets or trays designed for high-temperature air frying. The intense heat can also cause more wear on non-stick coatings, so handle your air fryer components with care.
