Oven temperature conversion that works in both directions. Type a gas mark, a Celsius, a Fahrenheit or a fan figure and the other three follow, so a recipe written for someone else's oven becomes one you can actually set. The full table is below.
| Gas mark | °C conventional | °C fan | °F | Description |
|---|---|---|---|---|
| ¼ | 110 | 90 | 225 | Very cool |
| ½ | 120 | 100 | 250 | Very cool |
| 1 | 140 | 120 | 275 | Cool |
| 2 | 150 | 130 | 300 | Cool |
| 3 | 160 | 140 | 325 | Moderate |
| 4 | 180 | 160 | 350 | Moderate |
| 5 | 190 | 170 | 375 | Moderately hot |
| 6 | 200 | 180 | 400 | Hot |
| 7 | 220 | 200 | 425 | Hot |
| 8 | 230 | 210 | 450 | Very hot |
| 9 | 240 | 220 | 475 | Very hot |
The gas mark column maps to the friendly Celsius and Fahrenheit numbers cooks actually set, which is why the °C and °F figures do not convert to each other exactly (350°F is really 177°C, rounded to 180°C). Domestic ovens are nowhere near accurate enough for those few degrees to matter. Fan ovens run hotter for the same dial, so the fan column sits about 20°C below the conventional one. Gas mark inputs snap to the whole marks; typing between marks reads the nearest. For the reasoning, the memorise-these settings and the exact Fahrenheit-to-Celsius list, see the oven temperature conversions reference.
What is gas mark 4 in degrees C?
180°C conventional, 160°C fan, 350°F. The general baking temperature.
What is 220 Celsius in gas mark?
Gas mark 7 (200°C fan, 425°F), a hot roasting and crisping setting.
What is 400°F in °C fan?
About 200°C conventional, so 180°C fan, which is gas mark 6.
Need the fan adjustment on its own?
