400 Fahrenheit to Celsius (400 °F to °C)

Formula and worked answer

°C = (°F − 32) × 5/9

Substituting 400 for °F: 400 × 0.555556 + -17.777778 = 204.4446 °C. The factor 0.555556 comes from the exact international definition of the degree Fahrenheit relative to the degree Celsius, so this answer is precise rather than rounded.

What does 400 Fahrenheit represent?

400 degrees Fahrenheit (204.44 °C) is the US oven setting standard for roast vegetables, roast meats, and high-temperature pizza in American home cookbooks. Converted to metric the result is 204.44 °C, which European ovens with 5° increments round to either 200 °C or 205 °C; ovens with 10° increments set 200 °C as the closest match. The 4 °C difference between an exact 204.44 °C target and a 200 °C oven setting is small enough to ignore for most roasts but produces visibly different colour development on Maillard-reactive surfaces like chicken skin, so cooks transferring a 400 °F US recipe to a metric oven sometimes adjust the setting up to 210 °C and shorten the time by a couple of minutes.
