Set your oven to this

No oven dial has a 121.1 °C mark. Recipes treat 250 °F and 120 °C as the same setting — gas mark ½ — and the gap between them is smaller than the swing of a domestic thermostat. Set a fan-forced oven to 100 °C.

250 °F is a very cool oven: holding food warm, slow-drying, and the long overnight cooks that barbecue recipes call for. On a metric oven it is 120 °C.
