To convert Fahrenheit to Celsius, subtract 32 and multiply by 5/9. To go the other way, multiply by 9/5 and add 32. The most common baking temperature, 350°F, is about 177°C, which most European recipes round to 180°C.
The chart below lists common oven settings with their gas marks for British-style ovens. If you use a fan or convection oven, lower the temperature by about 20°C (25°F) from the conventional setting, and check your food a little early, since fan ovens cook faster.
