🌡️ Oven Temperature Converter
Enter a temperature in Celsius, Fahrenheit, or gas mark and see all four equivalents at once — including the fan/convection setting — so any recipe works on your oven.

What is an Oven Temperature Converter?
It translates between the four ways ovens are labelled around the world — Celsius, Fahrenheit, British gas marks, and fan/convection — so a recipe written for one never leaves you guessing on another. Type in what the recipe says and read off what your dial needs.
Use it to follow an American recipe on a Celsius oven, set a gas oven from a fan temperature, or knock 25°F (about 14°C) off when you switch the fan on. Ovens drift from their dials, so pair it with an oven thermometer when the bake is fussy.
❓ Frequently Asked Questions
How does the oven temperature converter work?
Enter a temperature and its unit — Celsius, Fahrenheit, or gas mark — and it returns all four equivalents. Celsius and Fahrenheit convert with the standard formula (°F = °C × 9/5 + 32); gas marks follow the scale's definition (gas mark 1 is 275°F, then 25°F a step, so gas 4 = 350°F and gas 6 = 400°F, which UK charts round to 180°C and 200°C); and the fan figure is 25°F (about 14°C) below the conventional setting.
Why lower the temperature for a fan oven?
A fan (convection) oven circulates hot air, so it cooks faster and more evenly than a conventional oven at the same dial setting. Oven makers lower the setting by about 25°F (14°C) for convection, so 350°F conventional becomes 325°F. Many UK charts subtract 20°C instead; this tool uses the smaller manufacturer figure. Some ovens convert automatically, so check the manual before lowering it twice.
What is a gas mark?
Gas mark is the numbered scale used on many British gas ovens, running from 1 (275°F, about 140°C, a low oven) up to 9 (475°F, about 240°C, very hot), 25°F a step. Gas mark 4 (350°F, which UK charts round to 180°C) is the everyday baking temperature. This converter maps any temperature to its nearest gas mark.
How accurate are the conversions?
The Celsius–Fahrenheit conversion is exact. Gas marks are matched to the nearest step on the scale, and the fan adjustment is the 25°F (14°C) reduction oven makers use rather than a precise figure. Ovens also drift from their dials, so for anything temperature-critical use a separate oven thermometer.
