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.
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.
