To get there, use °C = (°F − 32) × 5/9. ## Values either side *Degrees Fahrenheit near 400, converted to degrees Celsius.* | Degrees Fahrenheit | Degrees Celsius | | --- | --- | | 212 °F | 100 | | 250 °F | 121.1111 | | 300 °F | 148.8889 | | 350 °F | 176.6667 | | 400 °F ← | 204.4444 | | 500 °F | 260 | | 750 °F | 398.8889 | | 1,000 °F | 537.7778 | ## How the conversion works The relationship is °C = (°F − 32) × 5/9. Both units measure temperature, so the conversion is a fixed formula that never changes. Temperature scales are the one common case where converting is not just multiplication — Celsius and Fahrenheit each put their zero in a different place, so an offset is applied as well as a scale factor. ## Common questions ### What is 400 °F in degrees Celsius? 400 °F is 204.4444 °C. ### How do you convert degrees Fahrenheit to degrees Celsius?
