About Oven Temperature Converter
Convert oven temperatures between Celsius, Fahrenheit, gas mark and fan (convection) settings, and read every equivalent from a single full chart. Type a temperature into any one system and the tool fills in the rest, so a recipe written in °F, a UK cookbook that lists gas mark 4, and a fan oven that only shows °C all line up in one place.
That last part is what generic temperature converters miss. Gas mark is a UK and Ireland scale, so if you are moving a recipe from a gas oven to an electric one — or the other way round — the gas-to-electric equivalents are already worked out for you. Fan ovens run roughly 20 °C (about 25 °F) hotter than conventional ovens, so the fan column drops the setting for you instead of leaving you to do the maths mid-bake. The chart also labels each row with its heat description, so you can see at a glance whether 200 °C counts as moderate, hot or very hot.
Use it to follow recipes from anywhere, double-check a temperature before you preheat, or settle whether 350 °F and 180 °C really are the same thing (they are, near enough). It is completely free with no sign-up, and it runs entirely in your browser — nothing you type is uploaded anywhere.
Frequently asked questions
- What is gas mark 4 in Celsius and Fahrenheit?
- Gas mark 4 is 180 °C or 350 °F — a moderate oven, and the most common baking temperature.
- How do I convert oven temperature from gas to electric?
- Find your gas mark in the chart and read across to the °C or °F column: gas mark 4 is 180 °C / 350 °F, gas mark 6 is 200 °C / 400 °F, and so on. If your electric oven is a fan model, use the fan column, which is already set about 20 °C lower than the conventional electric figure.
- How do I convert an electric oven temperature back to a gas mark?
- Enter the electric temperature in °C or °F and read the gas mark column. 160 °C / 325 °F is gas mark 3, 180 °C / 350 °F is gas mark 4, and 200 °C / 400 °F is gas mark 6. Gas marks step in fairly wide jumps, so pick the closest one to your setting.
- What temperature is a fan oven compared with a conventional one?
- Fan (convection) ovens circulate hot air, so set them about 20 °C (25 °F) lower than a conventional oven for the same result. The fan column in the tool already does this for you.
- Do I need to change the cooking time when I convert the temperature?
- Converting between °C, °F and gas mark usually leaves the time unchanged — 30 minutes at gas 4 is still 30 minutes at 180 °C. The exception is switching to a fan oven: because you drop the temperature by about 20 °C, some bakes also finish a few minutes sooner, so start checking early. This tool handles the temperature side; watch the food for the timing.
- What is 350 °F in Celsius?
- 350 °F is 180 °C, which is gas mark 4 and a moderate oven.
- What is gas mark 6 in Celsius?
- Gas mark 6 is 200 °C or 400 °F — a moderately hot oven, common for roasting and many breads.
- Why isn't my gas mark to Celsius conversion exact?
- Gas marks map to a range rather than a precise temperature, and recipe sources round them slightly differently (gas 4 is given as 177 °C or 180 °C). The tool uses the common rounded values.
- What counts as a moderate or hot oven?
- Moderate is around 180 °C / 350 °F / gas 4; hot is around 220 °C / 425 °F / gas 7. The chart lists the heat description for every setting.
- Is this oven temperature converter free and private?
- Yes. It is completely free with no sign-up, and every conversion runs in your browser, so the temperatures you enter are never uploaded to a server.
