The Formula Oven Temperature Converter (Fahrenheit to Celsius)
Formula:
°C = {(°F−32)× 5}÷9
Where:
- °C = Temperature in Celsius
- °F = Temperature in Fahrenheit
- 32 = Fahrenheit offset (freezing point of water)
- 5/9 = Conversion factor from Fahrenheit to Celsius

Why Convert Oven Temperatures?
Recipes vary between Fahrenheit and Celsius depending on the country. The U.S. commonly uses Fahrenheit, while most other countries use Celsius. Converting correctly ensures that food cooks at the right temperature, preventing overcooking or undercooking.

Fahrenheit to Celsius Conversion Formula
To convert Fahrenheit (°F) to Celsius (°C), use this formula:
°C={(°F−32)×5} ÷9
For example:
- 350°F → {(350−32)×5} ÷9=176.67°C
- 400°F → {(400−32)×5}÷9=204.44°C
Common Oven Temperature Conversions
Fahrenheit (°F) | Celsius (°C) | Oven Setting |
200°F | 93°C | Very Low |
250°F | 121°C | Low |
300°F | 149°C | Moderate |
350°F | 177°C | Medium |
400°F | 204°C | High |
450°F | 232°C | Very High |
500°F | 260°C | Maximum |
Quick Approximate Conversions
For a rough estimate without calculations:
- Multiply °F by 0.55 to get °C.
- Double °C and add 30 to get °F.
Examples:
- 375°F → 190°C (Close estimate)
- 180°C → 356°F (Close estimate)
How Different Ovens Affect Cooking
Different ovens may heat differently, even at the same temperature setting. Always check food a few minutes before the estimated cooking time. Convection ovens circulate hot air, cooking food faster than conventional ovens. Reduce the temperature by 25°F (about 15°C) when using a convection oven.
Cooking Tips for Accurate Temperature Use
- Use an Oven Thermometer: Built-in oven settings can be inaccurate. A separate thermometer ensures precise temperatures.
- Preheat Properly: Give the oven enough time to reach the correct temperature.
- Adjust for Fan Ovens: Reduce the temperature slightly for fan-assisted ovens.
- Check Food Early: Cooking times may vary based on the oven type.
Why Consistency in Temperature Matters
Incorrect temperatures can affect texture, moisture, and cooking time. For baking, precise temperature control ensures even cooking and prevents burnt or undercooked results.
Conclusion
Converting oven temperatures between Fahrenheit and Celsius is simple using the formulas and tables above. Whether baking a cake or roasting meat, accurate conversions help achieve the best cooking results. Use an oven thermometer for accuracy and adjust for different oven types when necessary.
