Gas Mark 7
Gas mark 7 is a hot oven:
220 °C
Conventional oven
425 °F
Fahrenheit
Fan-forced ovens run about 20 °C hotter than conventional at the same dial setting, so gas mark 7 is 200 °C with the fan on. See the full oven temperature conversion chart.
Gas mark 7 is the roasting setting: potatoes that need to go properly crisp, a joint that wants a hard start, pizza, and the opening blast that gives bread its crust. Note the ladder widens here — the jump from gas mark 6 is 20 °C, twice the step you get lower down the dial.

Frequently asked questions
What temperature is gas mark 7?
Gas mark 7 is 220 °C in a conventional oven, or 425 °F. In a fan-forced oven, set 200 °C instead.
Is gas mark 7 the same as 220 degrees?
Yes — gas mark 7 and 220 °C are the same setting, equal to 425 °F. It is the standard hot oven of British recipe writing.
What is the difference between gas mark 6 and gas mark 7?
Twenty degrees: gas mark 6 is 200 °C and gas mark 7 is 220 °C. The steps stop being even at this end of the dial, so estimating between them is unreliable.
What is gas mark 7 in a fan oven?
Set a fan oven to 200 °C — about 20 °C below the conventional figure. At this temperature the fan makes a real difference, so the adjustment matters more than it does for a slow bake.
