🌡️ 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 the usual 20°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 map to a fixed table (gas 4 = 180°C, gas 6 = 200°C, and so on); and the fan figure drops about 20°C from 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. The usual rule is to reduce the temperature by about 20°C — or roughly 25–50°F — to get an equivalent bake. This tool shows that fan-adjusted figure automatically.
What is a gas mark?
Gas mark is the numbered scale used on many British gas ovens, running from about 1 (140°C, a low oven) up to 9 (240°C, very hot). Gas mark 4 (180°C / 350°F) is the everyday baking temperature. This converter maps any temperature to its nearest gas mark on the standard table.
How accurate are the conversions?
The Celsius–Fahrenheit conversion is exact. Gas marks are matched to the nearest step on the conventional table, and the fan adjustment is the common 20°C guideline rather than a precise figure. Ovens also drift from their dials, so for anything temperature-critical use a separate oven thermometer.
