180°C, which is 350°F.
Each gas mark matches one set temperature, and the conversion is rounded to the nearest whole degree.
Celsius into gas mark
200°C
Gas mark 6, which is 400°F.
Fan ovens often need a lower setting than the figure in the recipe, so check the oven manual if results vary.
À propos de Oven Temperature Converter
Oven temperatures are written in different ways depending on where a recipe comes from. Many British recipes use Celsius and gas marks, while American recipes use Fahrenheit, so it is easy to end up with an oven that is far too hot or too cool. This oven temperature converter takes a temperature in Celsius, Fahrenheit or gas mark and shows the matching settings for both a conventional oven and a fan oven, along with the nearest gas mark. Enter the number from your recipe, choose its unit, and the answer appears straight away.
Fan ovens circulate hot air, so food cooks more evenly and often a little more quickly. The usual advice is to set a fan oven about 20 °C lower than a recipe states for a conventional oven, and this converter applies that rule to every result. Gas marks are a UK scale, where each mark matches one set temperature, such as gas mark 4 for 180 °C. Results are rounded to whole degrees, and every oven behaves a little differently, so check your handbook and keep an eye on the food as it cooks.
Comment utiliser Oven Temperature Converter
- Type the temperature from your recipe into the temperature box.
- Choose whether the number is in Celsius, Fahrenheit or gas mark.
- Choose conventional or fan oven to show the setting you need first.
- Read the headline setting, then check the full table for the other scales.
- Set the oven a few minutes early so it reaches the right temperature before the food goes in.

Questions fréquentes
What is gas mark 4 in Celsius?
Gas mark 4 is 180 °C, which is 356 °F. It is one of the most common settings in British baking, used for sponges, cakes and many casseroles. Gas marks run from 1/4 and 1/2 at the cool end, through 1 at 140 °C, up to 9 at 240 °C. Use the converter to find the nearest gas mark for any temperature, or check a gas mark table if you need an exact figure.
How much lower should a fan oven be?
A common rule is to reduce the temperature by about 20 °C for a fan oven compared with a conventional oven. So a recipe asking for 180 °C would suggest 160 °C in a fan oven. The reduction is a guide rather than a fixed rule, because ovens vary, so check your handbook and start with the lower setting if you are unsure how your oven behaves.
Why does 350 °F convert to 177 °C?
The exact figure for 350 °F is about 176.7 °C, which is rounded to the nearest whole degree for a simple oven setting. Ovens rarely show every fraction of a degree, so whole numbers are the practical choice. The gas mark closest to that temperature is gas mark 4, which sits at 180 °C, so a conventional oven at either setting gives a very similar result.
Are UK ovens marked in Fahrenheit?
Most UK ovens are marked in Celsius or gas marks, although some older cookers and imported appliances use Fahrenheit. The two scales are linked by a simple formula, so the converter makes switching quick. If your oven only has Celsius, convert the Fahrenheit figure from the recipe first, then set the nearest mark on the dial for the best result.
Can I use a gas mark on an electric oven?
Gas marks are a scale, so you can use the temperature the mark stands for on any oven. Find the Celsius figure for the gas mark, then set your electric oven to that temperature, or to the nearest mark on its dial. Electric and gas ovens heat in different ways, so you may need to watch the food and adjust the cooking time a little.
