Oven Temperature Converter (°F, °C, Gas Mark)
Convert between Fahrenheit, Celsius, gas mark and fan settings.
- Fahrenheit
- 350°F
- Celsius
- 180°C
- Gas mark
- 4
- Fan / convection
- 160°C
- Fan (convection) ovens run hotter — drop the dial about 20 °C (35 °F) versus a conventional oven.
- Gas marks are approximate; ovens vary, so use an oven thermometer for accuracy.
What is the Oven Temperature Converter?
This oven temperature converter translates between Fahrenheit, Celsius and UK gas marks, and shows the matching fan (convection) setting. It’s indispensable when a recipe is written for a different country’s oven dial — American recipes in °F, European in °C, British in gas marks. Enter a temperature, pick what unit it’s in, and get all the equivalents rounded to sensible oven values.
How to use the Oven Temperature Converter
- 1 Type in the temperature you have, or tap a common setting.
- 2 Choose whether it’s in Fahrenheit, Celsius, gas mark or a fan setting.
- 3 Read the equivalents in every unit, plus the fan-oven setting.
Oven temperature conversion chart — °F, °C, gas mark and fan
These are the standard rungs real recipes and real oven dials use, and the ones this converter snaps to. Ovens are calibrated to them, so a recipe saying 350 °F means gas mark 4, not a literal 176.7 °C.
| Gas mark | Fahrenheit | Celsius | Fan / convection | Typical use |
|---|---|---|---|---|
| Gas mark 1 | 275°F | 140°C | 120°C | Slow roasting, braises, meringues |
| Gas mark 2 | 300°F | 150°C | 130°C | Slow cooking, rich fruit cakes |
| Gas mark 3 | 325°F | 160°C | 140°C | Custards, cheesecake, low bakes |
| Gas mark 4 | 350°F | 180°C | 160°C | Most baking — cookies, cakes, brownies |
| Gas mark 5 | 375°F | 190°C | 170°C | Pastry, roasting vegetables |
| Gas mark 6 | 400°F | 200°C | 180°C | Roasting, pies, scones |
| Gas mark 7 | 425°F | 220°C | 200°C | Hot roasting, bread |
| Gas mark 8 | 450°F | 230°C | 210°C | Very hot — bread, pizza |
| Gas mark 9 | 475°F | 240°C | 220°C | Hottest setting — pizza, searing |
- Fan (convection) ovens circulate hot air and cook faster — drop the dial about 20 °C (35 °F) below the conventional setting, which is the fan column above.
- The exact arithmetic for 350 °F is 176.7 °C, but no oven has that mark. The ladder rounds to 180 °C, which is what recipes and dials actually mean.
- Gas marks are approximate and ovens drift with age — an oven thermometer is the only way to know what your oven is really doing.
Frequently asked questions
What is 180°C in Fahrenheit? +
180 °C is about 350 °F, which is gas mark 4 — one of the most common baking temperatures.
Should I lower the temperature for a fan oven? +
Yes. Fan (convection) ovens cook hotter, so reduce the dial by about 20 °C (25 °F) compared with a conventional oven, or use the fan figure shown here.
How accurate are the results? +
The figures come from standard, tested references (USDA FoodData Central and King Arthur Baking) and are excellent starting points. Ovens, ingredients and equipment vary, so treat the numbers as a reliable guide and adjust to taste and doneness.
Is this calculator free, and does it send my data anywhere? +
Yes — it’s completely free and runs entirely in your browser. Nothing you type is uploaded or stored on a server; the maths happens on your device, even offline once the page has loaded.
