Oven Temperature Converter: Celsius, Fahrenheit, and Gas Mark Without Burning Dinner

September 6, 2026

A British baking book, an American oven, and my confidence produced a loaf that was simultaneously raw inside and charcoal outside, because Gas Mark 6 is not 600 anything, and I guessed. Recipe traditions assume you share their measurement culture. Converters exist because cultures don’t.

Enter any oven temperature to get all three systems instantly: Celsius (°C), Fahrenheit (°F), and Gas Mark. The anchor points worth memorizing: 180°C = 350°F = Gas Mark 4 (the everyday baking default), 200°C = 400°F = Mark 6 (roasting), 220°C = 425°F = Mark 7 (crisping). Most recipes live within shouting distance of these three.

Beyond conversion, the accuracy lessons that actually fix baking: home ovens lie by 10–25°C routinely, so a cheap oven thermometer beats any converter for real results. Fan/convection ovens run hotter, drop 20°C (or ~25°F) from conventional-recipe temperatures. And preheating fully matters more than exact degrees; batter entering a half-hot oven spreads before it sets, no conversion can save it.

Bottom line: convert the number, verify with a thermometer, drop 20°C for fan ovens.
