Oven Temperature Conversion: Celsius to Fahrenheit Chart.
Published · By Convert & Calculate Everything
180 °C is 356 °F, which recipes round to 350 °F (gas mark 4). 200 °C is 392 °F, or 400 °F in a recipe, and 220 °C is 428 °F, or 425 °F. To convert any oven temperature, multiply the Celsius figure by 1.8 and add 32. For a fan oven, use about 20 °C less.
180 °C is exactly 356 °F, and recipes round it to 350 °F. 200 °C is 392 °F (recipes say 400 °F) and 220 °C is 428 °F (425 °F). The formula is °F = °C × 1.8 + 32, and to go the other way, °C = (°F − 32) ÷ 1.8.
Recipes round oven temperatures to the nearest 25 °F or 10 °C, because home ovens swing by several degrees as they cycle on and off. For any other temperature, use the temperature converter.

Exact Celsius to Fahrenheit values
Converted with °F = °C × 1.8 + 32, without rounding:

| 150 °C | 302 °F | 300 °F |
| 160 °C | 320 °F | 325 °F |
| 170 °C | 338 °F | 325 to 350 °F |
| 180 °C | 356 °F | 350 °F |
| 190 °C | 374 °F | 375 °F |
| 200 °C | 392 °F | 400 °F |
| 210 °C | 410 °F | 400 to 425 °F |
| 220 °C | 428 °F | 425 °F |
| 230 °C | 446 °F | 450 °F |
| 240 °C | 464 °F | 475 °F |
| 250 °C | 482 °F | 475 to 500 °F |
Fan ovens: lower the temperature by 20 °C
A fan (convection) oven blows hot air around the food, so it cooks faster at the same setting. Most oven manufacturers recommend lowering a conventional recipe temperature by about 20 °C, or 25 °F, when you use the fan: a recipe that says 180 °C becomes 160 °C fan. If a recipe already gives a fan temperature, use it as written.
How to convert an oven temperature by hand
For body and weather temperatures, see how to convert Celsius to Fahrenheit.
- Celsius to Fahrenheit: multiply by 1.8 and add 32. 180 × 1.8 = 324, + 32 = 356 °F.
- Fahrenheit to Celsius: subtract 32 and divide by 1.8. 350 − 32 = 318, ÷ 1.8 = 176.7 °C.
- Quick estimate: double the Celsius figure and add 30. 180 × 2 + 30 = 390, close enough for a sanity check but 34 °F too high, so use the exact formula for baking.

Step by step: Oven Temperature Conversion Chart
- Read the temperature in your recipe and note whether it is °C or °F.
- For °C to °F, multiply by 1.8 and add 32; for °F to °C, subtract 32 and divide by 1.8.
- Round to the nearest oven setting: 25 °F or 10 °C steps.
- If you use a fan oven, lower the result by about 20 °C or 25 °F.
