In the UK, oven temperatures are not only in Celsius/Centigrade, but quite often ovens will have what’s called a gas mark temperature. This can make cooking temperature conversions confusing. I have provided the table below to help sort it all out.
| Cooking Instructions | Fahrenheit | Celsius | Gas Mark |
| Very Hot | 475 | 245 | 9 |
| Very Hot | 450 | 230 | 8 |
| Hot | 425 | 220 | 7 |
| Quick/Fairly Hot | 400 | 205 | 6 |
| Moderately Hot | 375 | 190 | 5 |
| Moderate/Medium | 350 | 175 | 4 |
| Warm | 325 | 165 | 3 |
| Slow/Low | 300 | 150 | 2 |
| Very Slow/Very Low | 275 | 135 | 1 |
| Very Slow/Very Low | 250 | 120 | 1/2 |
| Very Slow/Very Cool | 225 | 110 | 1/4 |
