How to Convert Fahrenheit to Celsius
Converting from Fahrenheit to Celsius is simple with the right formula. Here's everything you need to know.
✓ The Formula
°C = (°F - 32) × 5/9
Or: °C = (°F - 32) ÷ 1.8
Step-by-Step Example
Let's convert 350°F to Celsius:
- Subtract 32: 350 - 32 = 318
- Multiply by 5/9: 318 × 5/9 = 318 × 0.556 = 176.7
- Result: 350°F = 176.7°C (approximately 177°C)
More Examples
Convert 400°F to Celsius:
- 400 - 32 = 368
- 368 × 5/9 = 204.4°C
- Result: 400°F = 204°C
Convert 425°F to Celsius:
- 425 - 32 = 393
- 393 × 5/9 = 218.3°C
- Result: 425°F = 218°C
Quick Mental Math Trick
For a rough estimate without a calculator:
- Subtract 30 and halve it: 350°F → (350 - 30) ÷ 2 = 160°C (close to actual 177°C)
- This gives you a ballpark figure that's usually within 15-20 degrees
- Good enough for understanding recipe temperatures quickly
Tips for Converting Recipe Temperatures
🌡️ Round to Nearest 10°
Most ovens don't have precise temperature control. Round Fahrenheit to the nearest 25° and Celsius to the nearest 10°. For example, 177°C rounds to 180°C.
⏲️ Adjust Baking Time
Different ovens heat differently. Start checking for doneness 5-10 minutes before the recipe says. Use visual cues and internal temperature.
🔥 Fan vs Conventional
US recipes often use conventional ovens. If using a fan/convection oven, reduce temperature by 25°F (15°C) or reduce time by 20%.
📏 Oven Thermometer
Many ovens run 25°F hotter or cooler than the dial shows. Use an oven thermometer to verify actual temperature for consistent results.
Frequently Asked Questions
What is 350°F in Celsius?
350°F = 176.7°C (approximately 177°C or 180°C). This is the most common baking temperature in US recipes, roughly equivalent to 180°C in European recipes. The formula: (350 - 32) × 5/9 = 176.7°C.
What is 400°F in Celsius?
400°F = 204.4°C (approximately 200°C or 205°C). This temperature is commonly used for roasting vegetables and baking. Formula: (400 - 32) × 5/9 = 204.4°C.
What is 425°F in Celsius?
425°F = 218.3°C (approximately 220°C). This is a hot oven temperature used for roasting and high-heat baking. The closest metric setting is 220°C.
How do you convert Fahrenheit to Celsius?
To convert Fahrenheit to Celsius: (°F - 32) × 5/9 = °C. Or subtract 32 and divide by 1.8. Example: (212 - 32) × 5/9 = 100°C (water's boiling point).
What temperature is 180°C in Fahrenheit?
180°C = 356°F (often rounded to 350°F). This is a common European baking temperature. Formula: (180 × 9/5) + 32 = 356°F.
Why do some countries use Fahrenheit and others use Celsius?
The United States primarily uses Fahrenheit, which sets water freezing at 32° and boiling at 212°. Most other countries use Celsius (part of the metric system), which sets water freezing at 0° and boiling at 100°. The UK switched from Fahrenheit to Celsius but some older recipes use Fahrenheit or Gas Marks.
What is Gas Mark temperature?
Gas Mark is used in the UK for gas ovens. Gas Mark 4 ≈ 350°F ≈ 180°C. Each Gas Mark increment is roughly 25°F or 15°C. Gas Mark 1 is lowest (275°F/135°C), Gas Mark 9 is highest (475°F/240°C).
Should I convert exactly or round?
For baking, round to the nearest common oven setting. Convert 350°F (177°C) to 180°C. Convert 400°F (204°C) to 200°C. Most ovens only allow 10°C or 25°F increments anyway, and this small difference won't affect most recipes.
What's the difference between fan and conventional oven temperatures?
Fan/convection ovens circulate hot air, cooking faster and more evenly. If a US recipe calls for conventional and you have convection, reduce temperature by 25°F (15°C) OR reduce cooking time by 20-25%. European recipes often assume fan ovens.
