Same value in every unit
400°F is 204.4°C. Subtract 32, then multiply by 5 and divide by 9: (400 − 32) × 5 ⁄ 9 = 204.4. Recipes round it to the nearest mark on a dial, and a European recipe for the same dish says 200°C.
In a fan oven, also called convection, use about 180°C: moving air cooks faster, so fan ovens run about twenty degrees lower than the recipe. On a British gas cooker, 400°F is gas mark 6.

Questions
What is 400°F in Celsius?
204.4°C. Recipes round it to 200°C, which is close enough for any oven.
What is 400°F in a fan oven?
About 180°C. A fan oven runs about twenty degrees Celsius cooler for the same result, because moving air carries heat to the food faster.
What gas mark is 400°F?
Gas mark 6. Each mark is about 25°F, or 14°C.
Is it accurate?
The conversion is exact; the oven is not. A home oven commonly runs ten to twenty degrees Celsius away from its dial and swings as its thermostat cycles, so the rounding recipes do is well inside the error you already have. An oven thermometer is the only way to know what yours really does.
