What is the 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."

Questions people ask
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.
