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.
