Convert between Fahrenheit, Celsius, and Gas Mark for baking, roasting, and everyday cooking.
Fan ovens are often set around 20°C lower than conventional oven recipes, though actual performance varies by appliance.
| Gas Mark | Fahrenheit (°F) | Celsius (°C) |
|---|---|---|
| 1 | 275°F | 135°C |
| 2 | 300°F | 149°C |
| 3 | 325°F | 163°C |
| 4 | 350°F | 177°C |
| 5 | 375°F | 191°C |
| 6 | 400°F | 204°C |
| 7 | 425°F | 218°C |
| 8 | 450°F | 232°C |
| 9 | 475°F | 246°C |
| 10 | 500°F | 260°C |

Recipes use different temperature systems depending on country, publisher, and age. American recipes often use Fahrenheit, most modern international recipes use Celsius, and older UK recipes may use Gas Mark.
Accurate temperature conversion helps with cake texture, bread rise, roast timing, browning, and even cooking. A small mismatch can change results more than many people expect.
Cooking and baking temperatures are not always written in the same format. Some recipes use Fahrenheit, others use Celsius, and many older British recipes refer to Gas Mark settings. This cooking temperature converter makes it easier to move between those systems without guessing.
It is useful for baking cakes, roasting meat and vegetables, adjusting oven instructions from international recipes, and checking the equivalent of older cookbook temperatures.
350°F in Celsius is 180°C, or Gas Mark 4. This is one of the most common baking temperatures, used for cakes, muffins, biscuits, and many standard recipes. When an American recipe calls for 350°F, setting the oven to 180°C gives the equivalent result.
180°C in Fahrenheit is 356°F, rounded to 350°F in most American recipes. In Gas Mark terms, 180°C corresponds to Gas Mark 4. It is the standard temperature for sponge cakes, shortbread, and most cookie recipes.
Gas Mark 4 in Celsius is 180°C (356°F). Gas Mark 4 is the most frequently used setting in older British recipes and is equivalent to a moderate oven.
200°C in Gas Mark is Gas Mark 6 (400°F). This is a hot oven, suitable for roasting vegetables, potatoes, and most joints of meat.
Gas Mark 6 in Celsius is 200°C (400°F). It represents a hot oven and is the most common roasting temperature in British recipes.
That means a recipe calling for 350°F, 180°C, or Gas Mark 4 may be pointing to almost the same oven setting.

| 500°F | 260°C | 10 | Extremely hot |
350°F is about 176.7°C, which is usually rounded to 180°C in cooking and baking.
180°C is usually treated as Gas Mark 4.
A fan oven is often set about 20°C lower than a conventional oven recipe, though appliance guidance should always take priority.
Different countries and older cookbooks use different systems. American recipes often use Fahrenheit, most modern international recipes use Celsius, and older British recipes may use Gas Mark.
Yes. It is useful for baking, roasting, casseroles, bread, cookies, cakes, and general recipe temperature conversion.
Fan ovens circulate hot air around the cavity, which typically makes them cook a little faster and more evenly than conventional ovens. As a rough guide, reducing the stated temperature by around 20°C gives a reasonable starting point when adapting a conventional recipe for a fan oven. For example, a recipe calling for 180°C in a conventional oven would typically be set to around 160°C in a fan oven. Always check the appliance instructions where available, as performance varies between models.
Oven dials are not always perfectly accurate, so an oven thermometer can still help with precise baking. For converting recipe temperatures, though, this tool provides a strong starting point for consistent results.
