What the Oven Descriptions Mean
Very low to low
Around 110°C to 150°C (gas mark 1/4 to 2). Used for slow cooking, drying, and gentle baking such as meringues.
Moderate
Around 160°C to 180°C (gas mark 3 to 4). A common all-purpose range for cakes, biscuits, and many bakes.
Moderately hot
Around 190°C to 200°C (gas mark 5 to 6). Good for pastries, pies, and many roasted dishes.
Hot
Around 220°C (gas mark 7). Used for bread, scones, and crisp roasting.
Very hot
Around 230°C and above (gas mark 8 to 10). Used for pizza and high-heat roasting.
Fan ovens
Fan ovens often run hotter, so many recipes lower the setting by around 20°C. Follow your recipe rather than converting.
Formulas and Method
Fahrenheit = (Celsius × 9/5) + 32
Celsius = (Fahrenheit - 32) × 5/9
Celsius and Fahrenheit convert with an exact formula because both are linear temperature scales. Gas mark is different. There is no exact formula for gas mark, so this converter uses a rounded lookup table of common oven equivalents and shows the closest gas mark to your temperature. Celsius and Fahrenheit results are rounded to whole degrees for everyday oven use. For other temperature pairs outside the kitchen, try the temperature converter.
Gas mark equivalents and oven descriptions are approximate. The values here are rounded and can vary by oven and recipe source. Fan ovens often need a lower setting than conventional ovens, so follow your recipe where possible. Not all ovens are calibrated exactly.
Worked Examples
180°C to Fahrenheit
180°C = 356°F (about 350°F on oven charts), gas mark 4, moderate oven.
350°F to Celsius
350°F = 177°C (often set as 180°C), gas mark 4, moderate oven.
Gas mark 6
Gas mark 6 = 200°C and 400°F, a moderately hot oven.
160°C to Fahrenheit
160°C = 320°F (about 325°F on oven charts), gas mark 3.
200°C to Fahrenheit
200°C = 392°F (about 400°F on oven charts), gas mark 6.
220°C to Fahrenheit
220°C = 428°F (about 425°F on oven charts), gas mark 7, hot oven.
Convert Recipe Temperatures with Care
International recipes
Recipes from different countries use Celsius, Fahrenheit, or gas mark. Converting carefully helps you avoid under-baking or burning.
Gas marks are a guide
Gas mark numbers are rounded steps, not exact temperatures. Treat them as a close guide and follow the recipe where you can.
Fan vs conventional
Fan ovens often need a lower setting than conventional ovens. This tool does not adjust for fan ovens, so use the recipe setting.
Check your oven
Ovens are not always calibrated exactly and can have hot spots. An oven thermometer helps you confirm the real temperature.
