120°C oven temperature
120°C = 100°C fan = gas mark 1/2 = 248°F
Very cool oven — very slow braises, overnight cooking.
Setting 120°C on a gas oven
120°C is not a gas mark. The nearest is mark 1/2 at 130°C, so on a gas oven you would set mark 1/2 and cook 10°C hotter than the recipe asks — usually worth a few minutes off the time.

Frequently asked questions
What is 120°C in a fan oven?
100°C. Subtract 20°C from a conventional-oven temperature to get the fan equivalent.
Can a gas oven be set to 120°C?
120°C is not a gas mark. The nearest is mark 1/2 at 130°C, so on a gas oven you would set mark 1/2 and cook 10°C hotter than the recipe asks — usually worth a few minutes off the time.
What gas mark is 120°C?
Gas mark 1/2, which is 250°F and conventionally written as 130°C.
What is 120°C in Fahrenheit?
248°F exactly. Recipes usually write it as 250°F, the gas mark step it sits closest to.
