Frequently Asked Questions
What is 400°F in Celsius?
400 degrees Fahrenheit equals 204.44 degrees Celsius.
What is the formula to convert Fahrenheit to Celsius?
Subtract 32 from the Fahrenheit value, then multiply by 5/9. Example: (400 − 32) × 5/9 = 204.44°C.
What Is 400°F Used For in Cooking?
400°F (204°C) is a high oven temperature used for roasting vegetables, baking crusty bread, cooking pizza, and achieving crispy skin on chicken. At this heat, the Maillard reaction — the browning of proteins and sugars — happens quickly, giving food a golden, caramelized finish.
Here are common foods cooked at 400 degrees Fahrenheit:
- Roasted vegetables (broccoli, potatoes, carrots) — 20–30 minutes
- Chicken thighs and drumsticks — 35–45 minutes
- Pizza — 12–18 minutes on a preheated stone
- Artisan bread and baguettes — 25–30 minutes
- Salmon fillets — 12–15 minutes
400°F vs. Nearby Oven Temperatures
| Temperature | Celsius | Best Used For |
|---|---|---|
| 325°F | 162.78°C | Slow roasting, cheesecakes |
| 350°F | 176.67°C | Cakes, cookies, muffins |
| 375°F | 190.56°C | Pies, casseroles |
| 400°F | 204.44°C | Roasting, bread, pizza |
| 425°F | 218.33°C | Crispy fries, sheet pan meals |
| 450°F | 232.22°C | High-heat searing, flatbreads |
Is 400°F the Same as 200°C?
Not exactly. 400°F equals 204.44°C, which is slightly above 200°C. If a recipe calls for 200°C and your oven only shows Fahrenheit, set it to 392°F — or round up to 400°F, which is close enough for most cooking purposes.
How Hot Is 400°F Compared to a Fan Oven?
Fan ovens (convection ovens) circulate hot air and cook food faster. If your recipe says 400°F for a conventional oven, reduce to around 375°F (190°C) for a fan oven, or follow the 25°F reduction rule.
What Is 400°F in Gas Mark?
400°F (204°C) is approximately Gas Mark 6. Gas marks are used in UK and some European recipes. Gas Mark 6 is considered a moderately hot oven, ideal for roasting and baking bread.
Nearby Conversions
400 f to c (204°C) is one of the most common roasting temperatures. At 400 f to c, potatoes turn golden and crispy, chicken skin renders properly, and most casseroles finish in under an hour. For reference, see the BBC Good Food oven temperature guide. Whether you are following a US recipe or converting for an oven thermometer, 400 f to c is one of the most practical conversions to know.
