Oven Temperature Converter
Move any oven setting between Fahrenheit, Celsius, and UK gas marks in one step.
Fahrenheit
350 °F
That's a common setting — gas mark 4 is roughly 350 °F / 180 °C.
Celsius
177 °C

How it works
Fahrenheit and Celsius are two scales for the same heat, tied together by a simple formula: °F = °C × 9/5 + 32. So 180 °C works out to exactly 356 °F, which most recipes round to 350 °F.
UK gas marks are a stepped scale rather than degrees. Gas mark 4 sits around 350 °F / 180 °C, and each mark up or down is roughly 25 °F. The converter picks the gas mark nearest to your temperature.
Pick what you're converting from, type the value, and the other two units update live. There's nothing to submit — the answer is always on screen.
Frequently asked questions
Why doesn't a temperature land on an exact gas mark?
Gas marks come in fixed steps, so most °F and °C values fall between two of them. The tool shows the closest mark — 340 °F rounds to gas mark 4, for instance.
Should I lower the temperature for a fan oven?
As a rule, drop a fan (convection) oven about 20 °C / 25 °F below what a recipe lists for a conventional oven, since the moving air cooks faster. This converter shows conventional temperatures.
What's the highest gas mark?
Gas mark 9, roughly 475 °F / 240 °C — hot enough for pizza and fast roasting. The scale also dips below 1 to marks 1/2 and 1/4 for gentle, low-and-slow cooking.
