Celsius, Fahrenheit and gas mark explained
Recipes from different countries use different oven scales. The UK and much of Europe use degrees Celsius, the US uses degrees Fahrenheit, and older British recipes use gas marks. The exact formula between Celsius and Fahrenheit is °F = °C × 9 ÷ 5 + 32, but in baking the values are usually rounded to the nearest familiar setting — for example 180°C is technically 356°F but written as 350°F. Gas mark 4 sits at that same moderate point used for most cakes and roasts.
If your recipe is for a conventional oven but you have a fan (convection) oven, lower the temperature by about 20°C, since the moving air cooks food faster.
FAQ
- What is 180°C in Fahrenheit?
- 180°C equals 356°F, which is usually rounded to 350°F in recipes. It is also Gas Mark 4 — the most common moderate baking temperature.
- What is Gas Mark 4?
- Gas Mark 4 is about 180°C or 350°F, a moderate oven used for most cakes, biscuits and roasts.
- How do I convert Celsius to Fahrenheit?
- Multiply the Celsius value by 9, divide by 5, then add 32. For example, 200°C × 9 ÷ 5 + 32 = 392°F (rounded to 400°F in recipes).
- Is fan oven temperature different?
- Yes. Fan (convection) ovens run hotter, so reduce the conventional temperature by about 20°C (or roughly 25°F). For example, 180°C conventional is about 160°C fan.
