Oven Temperature Conversion Guide: Celsius, Fahrenheit & Gas Mark
Following a recipe from a British cookbook when you have an American oven? Or trying to use a US recipe with a European appliance? Oven temperature conversions are one of the most common kitchen headaches — and one of the easiest to solve.
The Simple Formula
To convert Fahrenheit to Celsius: subtract 32, then multiply by 5/9. To go the other way, multiply by 9/5 and add 32. Or just use our Oven Temperature Converter and skip the math entirely.

Most Common Temperatures and What They're Used For
325°F / 160°C: Slow roasting, cheesecakes, custards. Low and slow gives you gentle, even cooking.
350°F / 180°C: The most common baking temperature. Cakes, cookies, muffins, and most quick breads are baked here.
375°F / 190°C: Slightly higher for quicker browning. Good for sheet pan cookies and some roasted vegetables.
400°F / 200°C: Roasting vegetables, chicken pieces, fish. High enough to caramelize without burning.
425–450°F / 220–230°C: Pizza, bread, and anything that needs a crisp crust. Also good for high-heat roasting.
Does Oven Type Matter?
Yes — convection (fan-assisted) ovens run hotter than conventional ovens. A general rule is to reduce the temperature by 25°F (about 15°C) when using a convection setting, or reduce cooking time by about 25%. If your oven has both modes, most baking is done in conventional mode unless the recipe specifies otherwise.
