Oven Temperature Converter
Convert oven temperatures between Celsius, Fahrenheit, and gas mark. Includes a fan-oven adjustment, a printable chart, and recipe presets.
Convert from
The European recipe default.
Type the °C value from your recipe. Decimals are accepted; the dial value is rounded to a whole number.
Subtracts 20 °C from the recipe temperature: the standard guidance for fan ovens.
Common recipe temperatures
Pick by recipe wording
Recipes often say "moderate oven" or "hot oven" instead of a number. Tap a band to load the standard temperature.
Oven temperature chart
| Gas mark | Celsius | Fahrenheit | Band | Use for |
|---|---|---|---|---|
| 1/4 | 110 °C | 225 °F | Very cool | Meringues, low and slow drying, keeping food warm. |
| 1/2 | 120 °C | 250 °F | Very cool | Slow rich casseroles, long-cook brisket, custards. |
| 1 | 140 °C | 275 °F | Cool | Slow roasts, rich fruit cakes, slow stews. |
| 2 | 150 °C | 300 °F | Cool | Rich fruit cakes, slow cooking of meat. |
| 3 | 160 °C | 325 °F | Warm | Milk puddings, baked custards, light fruit cakes. |
| 4 | 180 °C | 350 °F | Moderate | Victoria sponge, biscuits, brownies, baked potatoes. |
| 5 | 190 °C | 375 °F | Moderately hot | Pastries, choux pastry, sponge cakes, lasagne. |
| 6 | 200 °C | 400 °F | Moderately hot | Roast chicken, pies, tray-bake potatoes, scones. |
| 7 | 220 °C | 425 °F | Hot | Roast beef, puff pastry, pizza on a tray. |
| 8 | 230 °C | 450 °F | Very hot | Bread, hot pizza, blistered peppers. |
| 9 | 240 °C | 475 °F | Very hot | Sourdough crust, very hot pizza, searing. |
Chart values follow the standard UK gas-mark conventions used by BBC Good Food and traditional baking guides.
What the fan-oven rule does
- Subtract 20 °C: a fan oven moves hot air around so heat reaches food faster. Standard UK and Australian guidance is to drop the recipe temperature by 20 °C.
- Cook time: alongside the lower temperature, reduce the cook time by roughly 10 percent. Check 5 to 10 minutes early on long bakes.
- When to skip it:a recipe that already says "fan" or "convection" is written for the lower number; do not subtract again.
- Bread and pizza: for crusty bread and pizza, many home cooks prefer the conventional setting to avoid drying the surface.
Recipe shortcuts
- 350 °F = 180 °C = gas mark 4: the most common bake setting for cakes, brownies, and baked potatoes.
- 400 °F = 200 °C = gas mark 6: the standard for roast chicken and traybake potatoes.
- 425 °F = 220 °C = gas mark 7: hot enough for roast beef, pies, and puff pastry.
- 450 °F = 230 °C = gas mark 8: bread and pizza territory; preheat fully and use a stone if possible.
How to use
- Pick the unit your recipe uses: Celsius, Fahrenheit, or gas mark.
- Type the temperature, or tap a gas mark or recipe preset to load a common value.
- Read the four conversions: Celsius, Fahrenheit, the closest standard gas mark, and the recipe band (cool, moderate, hot, very hot).
- Tick I have a fan (convection) oven to see a second target temperature that subtracts 20 Celsius, with the matching Fahrenheit and gas-mark values.
- Use the Pick by recipe wording cards to jump straight to moderate, hot, or very hot oven settings without remembering the number.
- Click Copy summary to copy the full result, or Copy as table to copy the whole gas-mark chart.
About this tool
Oven Temperature Converter is a recipe-first tool for the four dial scales home cooks actually meet: Celsius, Fahrenheit, UK gas marks (1/4 through 9), and the fan-oven adjustment. Type the number from your recipe in any of the three units, or pick a gas mark from the chart, and the tool returns the matching value in every other unit alongside the recipe-style descriptive band (cool, warm, moderate, hot, very hot). Gas mark output snaps to the standard chart used in British baking guides and BBC Good Food, with a flag when your input falls between two marks and a note showing how far. Tick I have a fan (convection) oven to see a second target temperature that subtracts the conventional 20 Celsius adjustment, plus the matching Fahrenheit and gas-mark equivalents, so you know what to set without doing the math in the kitchen. A panel of common recipe temperatures (120, 150, 160, 170, 180, 190, 200, 220, 230 Celsius and 250 through 450 Fahrenheit) loads any value in one tap; a second panel maps recipe wording like moderate oven and hot oven to the number behind it. The full gas-mark reference chart at the bottom maps every gas mark to Celsius, Fahrenheit, descriptive band, and a typical use (meringues, baked custards, cakes, roast chicken, bread, pizza), and you can copy the whole chart as a tab-separated table that pastes cleanly into a notebook, recipe binder, or spreadsheet. Useful for converting US recipes for a UK oven, UK recipes for a US oven, conventional recipes for a fan or convection oven, and any moment a recipe says only gas mark 4 and your dial is in Celsius. Conversions run entirely in your browser; nothing is uploaded.
