Set your oven to this

No oven dial has a 204.4 °C mark. Recipes treat 400 °F and 200 °C as the same setting — gas mark 6 — and the gap between them is smaller than the swing of a domestic thermostat. Set a fan-forced oven to 180 °C.

400 °F is the American hot oven — roast vegetables, sheet-pan dinners, pastry and anything that needs browning rather than a slow even bake. On a metric dial it is 200 °C.
