Free Oven Temperature & Cooking Converter
Recipes from different countries specify oven heat in different systems entirely — American recipes in Fahrenheit, UK recipes often in gas mark, and everywhere else in Celsius — and a fan (convection) oven needs a lower set temperature than the recipe's stated conventional-oven temperature to avoid overcooking. This converter handles all three temperature systems in one place and applies the standard fan-oven adjustment automatically when you flip a switch.
It also includes a quick-reference chart of safe internal cooking temperatures for common meats and poultry (chicken, beef, pork, fish), since "done" temperature is a completely different number from oven-setting temperature and the two are easy to confuse when a recipe just says "cook until done."
Key features
Fahrenheit, Celsius and gas mark
Convert between all three oven temperature systems instantly.
Fan/convection oven adjustment
Automatically lowers the target temperature by the standard offset.
Meat doneness reference chart
Safe internal temperatures for chicken, beef, pork and fish.
Instant, no signup
Type a value in any field and see the others update live.
How to use it
- Type a temperature into any of the three fields (F, C or gas mark).
- Toggle Fan oven if your recipe was written for a conventional oven.
- Read the converted values in the other two systems.
- Check the meat doneness chart if you need a safe internal temperature.
Worked example
Example
A recipe calls for 350°F conventional → 177°C, gas mark 4 → fan oven adjusted to about 160°C / 325°F.

Tips for the best results
- Fan ovens typically need about 20°C (or 25°F) less than the same recipe written for a conventional oven — always check your oven's manual for its exact offset.
- Gas mark only maps approximately to Celsius/Fahrenheit — use the closest setting your oven offers.
- Meat doneness temperature is measured with a food thermometer in the thickest part, not by oven-setting temperature.
- Let meat rest a few minutes after cooking — the internal temperature typically rises slightly during resting.
Common mistakes to avoid
- Using a recipe's stated conventional-oven temperature directly in a fan oven without adjusting it down.
- Confusing the oven-setting temperature with the safe internal cooking temperature for meat — they are unrelated numbers.
- Assuming gas mark converts to an exact Celsius or Fahrenheit number — it's a stepped, approximate scale.

Frequently asked questions
How much lower should I set a fan oven?
As a general rule, about 20°C (or 25°F) lower than a recipe written for a conventional oven, though check your oven's manual since the exact offset varies by model.
What is gas mark 4 in Celsius?
Gas mark 4 is approximately 180°C (350°F), a very common baking temperature.
Is oven temperature the same as the safe cooking temperature for meat?
No — oven temperature is the air temperature setting, while safe cooking temperature is the meat's own internal temperature, checked with a food thermometer; they are entirely different numbers.
What's a safe internal temperature for chicken?
165°F (74°C) at the thickest part, per standard food-safety guidance.
Does this work for all oven brands?
The Fahrenheit/Celsius/gas mark conversions are standard, but the exact fan-oven offset can vary slightly by manufacturer — check your manual if precision matters.
