How to Use This Converter
Enter a temperature, select the unit you're converting from, and the converter instantly shows the equivalent in Fahrenheit, Celsius, and Gas Mark. The full reference chart below the converter covers the most common oven settings used in recipes.
Conventional vs Convection Ovens
If your oven has a fan (convection or fan-assisted mode), reduce the recipe temperature by 25°F (about 15°C), or reduce the cooking time by around 20–25%. Fan ovens circulate hot air more efficiently, which means food cooks faster and more evenly — but also more quickly browns or dries out if you don't adjust.
When a recipe doesn't specify, assume it was written for a conventional (non-fan) oven.
Frequently Asked Questions
What is 350°F in Celsius?
350°F is 177°C, or Gas Mark 4. This is the most common baking temperature for cakes, cookies, and muffins.
What is 180°C in Fahrenheit?
180°C is 356°F, which rounds to 350°F in most recipes. Gas Mark 4.
What is Gas Mark 6 in Celsius?
Gas Mark 6 is 200°C (400°F). Good for roasting vegetables, chicken pieces, and fish.
Why do some recipes say "moderate" or "hot" oven?
Older recipes — especially British ones — often describe oven temperature by feel rather than number. A moderate oven is around 350°F (180°C), a hot oven is 400–425°F (200–220°C), and a very hot oven is 450°F (230°C) or above.
Frequently Asked Questions
What is 180°C in Fahrenheit?
180°C equals 356°F, typically rounded to 350°F in American recipes. This is one of the most common baking temperatures, used for cakes, cookies, muffins, and casseroles. At 350°F, food cooks evenly without browning too quickly on the outside.
What is 200°C in Fahrenheit?
200°C equals 392°F, rounded to 400°F in most recipes. This is a moderately high temperature used for roasting chicken, baking pizza, roasting vegetables, and baking bread. It produces good browning without burning.
How do I adjust recipes for a fan (convection) oven?
Fan ovens cook 20–25% faster because they circulate hot air. If a recipe was written for a conventional oven, reduce the temperature by 25°F (15°C) or reduce the cook time by 20%. Most modern ovens indicate the fan setting — use it for roasting and baking, but turn it off for delicate items like soufflés or custards.
