What Is 400°F in Celsius?
400 degrees Fahrenheit is 204.444 degrees Celsius, normally written as 200 °C.
How to Convert Fahrenheit to Celsius
To convert degrees Fahrenheit to degrees Celsius, subtract 32, then multiply by 5/9.
For example: 75 °F − 32 = 43, and 43 × 5/9 = 23.8889 °C.
Where You Meet This Number
American recipes use 400 °F for roasting vegetables, baking biscuits and anything that should brown rather than simply cook through. Metric recipes write that same heat as 200 °C.
Roasted broccoli at 400 °F for 20 minutes becomes 200 °C for 20 minutes.
What People Get Wrong
Sheet-pan recipes at 400 °F assume the pan is hot and the food is in a single layer. Crowding the pan drops the effective temperature and steams the food instead of roasting it, no matter which scale you set the dial in.

About These Scales
Degree Fahrenheit
On the Fahrenheit scale water freezes at 32 degrees and boils at 212 degrees, so one Fahrenheit degree is 5/9 the size of a Celsius degree. It remains the standard scale for weather, ovens and body temperature in the United States.
Degree Celsius
The Celsius scale puts the freezing point of water at 0 degrees and its boiling point at 100 degrees at sea level. It is the everyday temperature scale in nearly every country except the United States.

Frequently Asked Questions
Is 400 °F exactly 200 °C?
No. 400 °F is 204.444 °C. Recipes write 200 °C because that is a real dial setting, and 4 degrees makes no practical difference.
What gas mark is 400 °F?
Gas mark 6, which British recipes describe as moderately hot.
What is 400 °F on a fan oven?
About 180 °C. Fan ovens run roughly 20 °C hotter in effect than their setting.
What is 400 °F in kelvin?
400 °F is 477.594 K on the absolute scale.
