Oven Temperature FAQ
350 degrees Fahrenheit equals 176.67 degrees Celsius, which most recipes round to 175C or 180C. On a gas oven, 350F corresponds to Gas Mark 4. This is the most common baking temperature for cakes, brownies, chocolate chip cookies, and most everyday baked goods. When a recipe simply says moderate oven, 350F is the standard interpretation.
400 degrees Fahrenheit equals 204.4 degrees Celsius, typically written as 200C in recipes. This corresponds to Gas Mark 6. A 400F oven is considered hot and is the standard temperature for roasting vegetables, baking pizza, making French fries, and cooking dishes that need a crispy exterior and rapid browning.
To convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit temperature and then multiply by 5/9. The formula is: Celsius equals (Fahrenheit minus 32) multiplied by 5 divided by 9. For 350F: 350 minus 32 equals 318, and 318 times 5/9 equals 176.67C. To convert Celsius to Fahrenheit, multiply by 9/5 and add 32.
Gas Mark 4 equals 350 degrees Fahrenheit or 175 degrees Celsius. Gas Mark 4 is described as a moderate oven and is the most commonly called-for temperature in British and Australian recipes. The full gas mark scale runs from Gas Mark 1 at 275F to Gas Mark 9 at 475F, with each mark representing an increase of approximately 25 degrees Fahrenheit.
Most standard bread recipes bake at 375F to 450F, or 190C to 230C. Simple sandwich loaves and dinner rolls bake well at 375F to 400F (190C to 200C), which is Gas Mark 5 to 6. Artisan breads with a crispy crust require 425F to 450F (220C to 230C), which is Gas Mark 7 to 8. Higher temperatures create oven spring, better crust color, and a crispier exterior on lean doughs.
A slow oven temperature is 250F to 325F, or 120C to 165C, which corresponds to Gas Mark 1/2 to Gas Mark 3. Slow oven temperatures are used for long-baking items like meringues, low-and-slow roasts, dried fruit, and dehydrating. Many slow cooker and braise recipes that finish in the oven use temperatures in the 275F to 300F range, which equals 135C to 150C.
Yes. A fan or convection oven circulates hot air and cooks approximately 25 degrees Fahrenheit (about 15 degrees Celsius) hotter than a conventional oven at the same setting. When using a fan oven, reduce the recipe temperature by 25F or 15C from the stated temperature, or reduce baking time by about 20 percent. For example, if a recipe calls for 350F in a conventional oven, set a fan oven to 325F or 165C.
