Oven temperatures

# °F, °C or gas mark?

Type the temperature your recipe gives and see it in every other scale, plus roughly where to set a fan oven.

## Gas marks and common oven settings

| Gas mark | °F | °C in recipes | °C exact | Fan oven, about | Often called |
| --- | --- | --- | --- | --- | --- |
| ¼ | 225 °F | 110 °C | 107 °C | 90 °C / 200 °F | Very cool |
| ½ | 250 °F | 120 °C | 121 °C | 100 °C / 225 °F | Very cool |
| 1 | 275 °F | 140 °C | 135 °C | 120 °C / 250 °F | Cool |
| 2 | 300 °F | 150 °C | 149 °C | 130 °C / 275 °F | Cool |
| 3 | 325 °F | 170 °C | 163 °C | 150 °C / 300 °F | Moderately slow |
| 4 | 350 °F | 180 °C | 177 °C | 160 °C / 325 °F | Moderate |
| 5 | 375 °F | 190 °C | 191 °C | 170 °C / 350 °F | Moderately hot |
| 6 | 400 °F | 200 °C | 204 °C | 180 °C / 375 °F | Moderately hot |
| 7 | 425 °F | 220 °C | 218 °C | 200 °C / 400 °F | Hot |
| 8 | 450 °F | 230 °C | 232 °C | 210 °C / 425 °F | Very hot |
| 9 | 475 °F | 240 °C | 246 °C | 220 °C / 450 °F | Very hot |
| 10 | 500 °F | 260 °C | 260 °C | 240 °C / 475 °F | Extremely hot |

## Using the converter

Type the number from your recipe and choose its scale. Gas marks go from ¼ to 10; mark 1 is 275 °F and every mark above it adds 25 °F. Celsius recipes round to the nearest 10 degrees, so 350 °F becomes 180 °C on the page even though the exact figure is 177 °C. The converter shows both.

A fan oven blows hot air around the food, so it cooks a little faster at the same setting. The usual guideline is to set it about 20 °C (25 °F) lower than a recipe written for a conventional oven, or to keep the temperature and check for doneness earlier. If your recipe already gives a fan temperature, pick "A fan oven" and the converter works the other way. Ovens vary, so an oven thermometer is the best way to know what yours really does.

### Sources

Gas mark figures follow the conventional table summarised in [Wikipedia's article on gas marks](https://en.wikipedia.org/wiki/Gas_mark). The fan adjustment is a common guideline, not a rule.

## Questions

**Is 180 °C the same as 350 °F?**

Close enough for cooking. 350 °F is 177 °C exactly, and recipes round it to 180 °C. Both are gas mark 4.

**Should I lower the temperature for every fan oven recipe?**

Only when the recipe was written for a conventional oven. Many newer recipes give both temperatures; use the fan one as it is.
