Gas Mark 2
Gas mark 2 is a cool oven:
150 °C
Conventional oven
300 °F
Fahrenheit
Fan-forced ovens run about 20 °C hotter than conventional at the same dial setting, so gas mark 2 is 130 °C with the fan on. See the full oven temperature conversion chart.
Gas mark 2 is a cool oven — slow-cooked casseroles, pulled shoulder, confit, overnight beans and the low end of meringue baking. Nothing browns quickly here; the point of the setting is time rather than heat, and recipes that use it usually run for hours.

Frequently asked questions
What temperature is gas mark 2?
Gas mark 2 is 150 °C in a conventional oven, or 300 °F. In a fan-forced oven, set 130 °C instead.
Is gas mark 2 the same as 150 degrees?
Yes — gas mark 2 and 150 °C are the same setting, equal to 300 °F. British recipes describe it as a cool oven.
What is the difference between gas mark 1 and gas mark 2?
Ten degrees: gas mark 1 is 140 °C and gas mark 2 is 150 °C. At these temperatures a 10 °C difference changes the timing noticeably over a long cook, even though it sounds small.
What is gas mark 2 in a fan oven?
Set a fan oven to 130 °C. For slow cooking, many ovens hold low temperatures poorly, so an oven thermometer is worth more here than anywhere else on the dial.
