Oven Temperature Converter
US recipes give oven temperature in Fahrenheit, UK recipes often use gas mark, and most of the rest of the world uses Celsius. Convert between all three below.
Gas mark shown is the closest standard setting — ovens don't have a gas mark for every possible temperature.

Common questions
What is 350 F in Celsius?
350°F is 177°C, usually rounded to 180°C in recipes — the most common baking temperature for cakes and cookies.
What is gas mark 4 in Celsius and Fahrenheit?
Gas mark 4 is 180°C, which is 350°F — a standard medium oven setting used across many UK recipes.
Do I need to adjust temperature for a fan or convection oven?
Most recipe temperatures assume a conventional oven. For a fan or convection oven, lower the temperature by about 20°C (or 25°F), since the moving air cooks food faster at the same setting.
