Oven Temperature Converter
Enter an oven temperature in °C or °F, or pick a gas mark, and instantly see the matching conventional °C and °F, the fan (convection/fan-forced) settings, the UK gas mark and a plain-English heat level (from very cool to very hot). Values follow the standard oven charts cooks expect — 180 °C is shown as 350 °F and gas mark 4, not the exact 356 °F — and fan settings use the usual reduction of 20 °C / 25 °F from conventional. Great for following recipes across countries, converting an American °F recipe for a European °C oven, or working out the fan-oven equivalent. Everything is computed locally in your browser.

Frequently asked questions
- What is 180 °C in Fahrenheit and gas mark?
- In oven terms, 180 °C = 350 °F = gas mark 4, with a fan setting of about 160 °C. The exact arithmetic gives 356 °F, but oven charts round to the familiar 350 °F, which is what this tool shows.
- How do I convert a conventional oven to fan (convection)?
- Lower the temperature by about 20 °C (25 °F). So a recipe calling for 200 °C conventional becomes roughly 180 °C fan. Fan ovens circulate hot air, so they cook faster and more evenly at a lower set temperature.
- What are gas marks?
- Gas marks are the UK gas-oven scale. Gas mark 1 = 275 °F/140 °C, and each mark up adds 25 °F, up to gas mark 9 = 475 °F/240 °C. Below 1 there are gas mark ½ (250 °F) and ¼ (225 °F) for very low, slow cooking.
- Why doesn't the exact °C↔°F match the chart?
- Standard oven charts pair round numbers (180 °C with 350 °F) even though the exact conversion is 356 °F. This tool follows the charts so your settings match recipe books and oven dials, then snaps any input to the nearest standard setting.
