Oven Temperature Converter

What this tool does

This converter translates oven temperatures between the three scales home cooks meet most often: Fahrenheit, Celsius and UK gas marks. Enter a temperature in any one of them and the other two appear instantly, along with a plain-language description — “moderate”, “hot”, “very cool” — so you know what kind of heat the recipe is really asking for.

It exists because recipes travel. An American recipe gives 425°F, a European one gives 220°C, and an old British baking book says gas mark 7. They are all describing nearly the same oven, but unless you can convert between them quickly, half the world’s recipes are awkward to follow. The tool loads with 350°F — the everyday “moderate oven” — already converted, so you can see how it behaves at a glance.

When you would use it

The classic case is cooking from a recipe written for a different country. If your oven dial is in Celsius and the recipe is in Fahrenheit, or your oven uses gas marks and a modern recipe does not, this converter gets you to the right setting in seconds. It is also useful when a recipe quotes a gas mark and you want to know roughly how hot that is, or when you are adapting an old family recipe whose oven references no longer match your appliance.

Bakers reach for it when a recipe gives only one scale and they want to double-check, and anyone with a dual-scale oven uses it to confirm which number on the dial matches the instruction.

How to use it

1. Choose which scale your recipe uses: Fahrenheit, Celsius or Gas mark.
2. For Fahrenheit or Celsius, type the temperature. For gas mark, tap the mark shown on your dial, from ¼ up to 9.
3. Read the three result cards. You get the equivalent in all three scales at once, plus the descriptive name of that heat level.
4. Use Copy result to save the converted setting to your notes.
5. Scroll down for the full reference table of common settings if you would rather look the value up directly.

How to read the result

The descriptive names — cool, warm, moderate, hot, very hot — come from the traditional oven scale and are a quick sanity check: if a recipe says “bake in a moderate oven” with no number, that is around 350°F, 180°C, gas mark 4. The reference table at the bottom lays out the standard pairings so you can scan them at a glance.

Remember the fan-oven adjustment: if your oven has a fan, set it about 20°C (25–30°F) below the conventional figure shown here. And because home ovens drift, an inexpensive oven thermometer is the most reliable way to know your true temperature.

For converting the ingredients themselves, the cups to grams converter handles cup-to-weight measurements, and the recipe scaler adjusts a whole ingredient list up or down. The cocktail measurement converter covers bar units, and the general unit converter handles length, volume and more. To keep an eye on baking time, use the countdown timer.
