The Gas Mark scale is uniquely British, ranging from 1/4 to 9 with each full mark representing about 25-30°C. Gas Mark 4 specifically equates to 343 F or 173°C, making it a versatile mid-range temperature. Many classic British recipes, from shepherd's pie to Victoria sponge, call for this setting. When using an air fryer, you might need to adjust cooking times slightly as they cook more efficiently. Our air fryer conversion chart provides detailed guidance for all your temperature conversion needs.
Historically, Gas Marks were developed when most British homes used gas ovens without precise temperature controls. Today, even with modern appliances, many traditional recipes still reference this system.

While 343 F always equals Gas Mark 4, how you apply this temperature varies by appliance. Conventional ovens may have hot spots, requiring occasional tray rotation. Fan-assisted ovens cook about 20°C hotter than their setting indicates, so you'd typically reduce the temperature accordingly.

For baking enthusiasts, our cake recipes showcase how to adapt traditional Gas Mark recipes for air fryers.
Modern combi ovens with air fryer functions often allow you to select either Fahrenheit or Gas Mark settings directly. If yours doesn't, remember that 343 F is your Gas Mark 4 equivalent.
