Celsius to Fahrenheit Converter
European and Australian recipes list oven heat in Celsius; many American cards still use Fahrenheit. Type either scale, drag the slider, or tap a preset — get the other number in seconds for dialing your oven or comparing two versions of the same dish.

When you only need a temperature swap
Moving a sponge cake from a British magazine (180°C fan) to a US dial often means hunting “350°F” on the ring — not rethinking the whole bake. The same goes for candy thermometers, proofing dough in a cool kitchen, or reading a USDA chart in °F when your oven display is in °C.
If the recipe also moves from a large oven to a compact air fryer, temperatures usually drop and times shrink. That is a different adjustment — handled on the air fryer conversion calculator, not here.
Need gas marks or fan-versus-conventional equivalents too? Use the oven temperature chart to translate the full oven setting instead of only swapping units.
Gas mark quick reference
Gas marks appear on British and Irish cookers. Values below are typical center-shelf equivalents — verify with an oven thermometer if browning looks off.
| Gas | °C | °F | |
|---|---|---|---|
| ¼ | 110°C | 225°F | — |
| ½ | 120°C | 250°F | — |
| 1 | 140°C | 275°F | — |
| 2 | 150°C | 300°F | — |
| 3 | 160°C | 325°F | — |
| 4 | 180°C | 350°F | Most cakes & cookies |
| 5 | 190°C | 375°F | — |
| 6 | 200°C | 400°F | — |
| 7 | 220°C | 425°F | — |

FAQ
- What is the formula for Celsius to Fahrenheit?
- Multiply Celsius by 9/5, then add 32. Example: 180°C × 9/5 + 32 = 356°F (often rounded to 350°F on dial ovens). This calculator rounds to whole degrees for everyday cooking.
- Why do American recipes use 350°F so often?
- 350°F (about 175–180°C) sits in the moderate oven band where many cakes, cookies, and casseroles bake through without burning the edges first. It is a practical default, not a scientific sweet spot for every food.
- Is gas mark the same in every country?
- Gas marks are most common on UK and Irish cookers. Marks map to approximate oven temperatures; always confirm with an oven thermometer because jets and calibration vary.
- Does this replace the air fryer conversion calculator?
- No. This page only swaps °C and °F. The air fryer tool also lowers temperature and shortens time when moving from a conventional oven to a basket — use that when the recipe was written for a full oven.
