Fahrenheit to Celsius Converter

Understanding Fahrenheit to Celsius

Fahrenheit and Celsius are different temperature scales with different zero points. The conversion formula is: Celsius = (Fahrenheit - 32) × 5/9. Common baking temperatures include 350°F (177°C, often rounded to 180°C) for cakes and 400°F (204°C, often rounded to 200°C) for bread. The scales meet at -40°, where both read the same.

When to Use Fahrenheit to Celsius

Following an American recipe with a Celsius oven? Converting Fahrenheit to Celsius is necessary when you need to understand temperatures in the metric system. Most of the world uses Celsius, while the United States primarily uses Fahrenheit. This conversion is essential for anyone outside the US following American cookbooks, food blogs, or recipes.

Practical Tips

This conversion is essential for oven temperatures. The most common American baking temperature is 350°F, which converts to approximately 177°C (usually rounded to 180°C). When using fan ovens, remember to reduce the temperature by 20°C from the conventional oven setting. Use an oven thermometer — most home ovens are inaccurate by 10-30°C. For more details, see our complete oven temperature guide.

Quick Tips

• 350°F = 177°C (usually rounded to 180°C) — the most common baking temperature
• 400°F = 204°C (usually rounded to 200°C)
• To convert: subtract 32 from Fahrenheit, then multiply by 5/9
• Use an oven thermometer — most home ovens are inaccurate

Common Mistakes to Avoid

A frequent error is using 350°F = 180°C as an exact conversion when it's actually 177°C. While this 3°C difference rarely matters, it can affect delicate baking. Another mistake is forgetting to adjust for fan/convection ovens — if the recipe was developed with a conventional American oven, reduce by 20°C for fan ovens after converting. Also, don't assume your oven is accurate; use a thermometer.

When Precision Matters

Precision is critical for candy making, where stages like soft ball (234-240°F / 112-116°C) and hard crack (300-310°F / 149-154°C) require exact temperatures. For bread baking, the difference between 200°C and 210°C affects crust formation. For roasting and general cooking, rounding to the nearest 5°C is usually fine.
