Celsius to Fahrenheit
Written by Mustapha B. · Updated August 13, 2026
Convert Celsius to Fahrenheit using the formula (°C × 9/5) + 32. Enter any temperature below to follow recipes written in °F.
180 °C =
356 °F
To convert Celsius to Fahrenheit, multiply the Celsius figure by 9/5 and then add 32. So a 180°C oven becomes (180 × 9/5) + 32, which equals 356°F, generally rounded to 350°F for baking. Familiar oven points convert cleanly: 160°C is about 325°F, 200°C is roughly 400°F, and 220°C lands near 425°F. Since oven dials and recipes round to the nearest five or ten degrees, you don't need to chase exact decimals.
Use this converter whenever a metric recipe gives temperatures in Celsius but your oven reads in Fahrenheit. Type the Celsius value and you'll get a Fahrenheit setting you can dial straight in. A helpful tip: if the original recipe was written for a fan oven, the stated Celsius is already lowered, so when you convert to a conventional Fahrenheit oven you may want to add roughly 25°F back to match the intended browning and rise.
Fahrenheit, Celsius and gas mark, how they relate
US recipes use Fahrenheit, most of the world uses Celsius, and UK gas ovens use Gas Mark. The conversions are simple: °C = (°F − 32) × 5/9 and °F = (°C × 9/5) + 32. Gas Mark is a stepped scale, so we snap to the nearest mark when you convert to it.
Gas mark conversion chart
| Gas Mark | °C | °F | Description |
|---|---|---|---|
| 1 | 140°C | 275°F | Cool |
| 2 | 150°C | 300°F | Cool |
| 3 | 170°C | 325°F | Warm |
| 4 | 180°C | 350°F | Moderate |
| 5 | 190°C | 375°F | Moderately hot |
| 6 | 200°C | 400°F | Fairly hot |
| 7 | 220°C | 425°F | Hot |
| 8 | 230°C | 450°F | Very hot |
| 9 | 240°C | 475°F | Very hot |
Common baking temperatures
| What you’re baking | °F | °C | Gas Mark |
|---|---|---|---|
| Slow roasting / low & slow | 250°F | 120°C | ½ |
| Meringues, dehydrating | 275°F | 140°C | 1 |
| Custards, slow bakes | 325°F | 170°C | 3 |
| Cookies, cakes, brownies | 350°F | 180°C | 4 |
| Muffins, quick breads | 375°F | 190°C | 5 |
| Yeast bread, roasting veg | 400°F | 200°C | 6 |
| Pastry, scones | 425°F | 220°C | 7 |
| Artisan bread, hot roast | 450°F | 230°C | 8 |
| Pizza, very hot | 500°F | 260°C | 10 |
Fan (convection) ovens run hotter, reduce the temperature by about 20°C (25°F), or one gas mark, and check a little early.
Frequently asked questions
What is 180°C in Fahrenheit?
180°C is about 356°F, which is normally set as 350°F on a Fahrenheit oven. It's the standard temperature for many cakes and cookies.
What is the formula to convert Celsius to Fahrenheit?
Multiply the Celsius value by 9/5 and add 32. For example, (100 × 9/5) + 32 equals 212°F, the boiling point of water.
