UK gas marks in °C and °F
Gas mark °F values are rounded, so they can differ from the exact conversion by a few degrees.
| Gas mark | °C | °F |
|---|---|---|
| Gas mark 1 | 140 | 275 |
| Gas mark 2 | 150 | 300 |
| Gas mark 3 | 160–170* | 325 |
| Gas mark 4 | 180 | 350 |
| Gas mark 5 | 190 | 375 |
| Gas mark 6 | 200 | 400 |
| Gas mark 7 | 220 | 425 |
| Gas mark 8 | 230 | 450 |
| Gas mark 9 | 240 | 475 |
* Sources differ: two UK oven charts give gas mark 3 as 160 °C and 170 °C.
Fan ovens
For a fan oven, subtract 20 °C from the conventional temperature, so 180 °C becomes 160 °C. A fan blows hot air around the food, so it cooks at a lower setting.
