Fahrenheit vs Celsius for Cooking: Key Differences Explained
Compare Fahrenheit and Celsius temperature scales for cooking, with common oven temperature conversions.
Quick Answer
US recipes use Fahrenheit; international recipes use Celsius. The key conversion: 350°F = 180°C.
| Feature | Fahrenheit | Celsius |
|---|---|---|
| Standard in US recipes | Standard in international and European recipes | |
| Common oven range: 300-500°F | Common oven range: 150-260°C | |
| Water boils at 212°F | Water boils at 100°C | |
| More granular for precision without decimals | Requires decimals for equivalent precision |
Most American recipes use Fahrenheit for oven temperatures and internal meat temperatures. Common baking temperatures like 350°F and 425°F are second nature to US cooks but confusing for those accustomed to Celsius.
International and European recipes use Celsius. Understanding the conversion (°C = (°F - 32) x 5/9) is essential when following recipes from different countries. Key reference: 180°C equals 350°F, the most common baking temperature.
When to Use Fahrenheit
- Following American recipes
- Using an oven calibrated in Fahrenheit
- Checking internal meat temperatures with a US thermometer
When to Use Celsius
- Following European or international recipes
- Using an oven calibrated in Celsius
- Professional culinary settings outside the US
Worked Example
A British recipe calls for 200°C.
Fahrenheit
In Fahrenheit: (200 x 9/5) + 32 = 392°F (round to 400°F).
Celsius
In Celsius: 200°C as stated.
When converting, rounding to the nearest 25°F is standard practice for oven settings.

Frequently Asked Questions
What are the most common oven conversions?
325°F=160°C, 350°F=180°C, 375°F=190°C, 400°F=200°C, 425°F=220°C, 450°F=230°C.
Do gas mark ovens use a different scale?
Yes, gas marks are a separate scale used in the UK. Gas mark 4 equals 350°F / 180°C.
Does altitude affect cooking temperature?
Altitude affects boiling point (water boils below 212°F/100°C at high altitude), which can require recipe adjustments.
