204 $^{\circ}$C 478 K
This question asks us to convert a measurement in Fahrenheit to both Celsius and Kelvin. To convert to Celsius, we use the formula $^{\circ}$C=($^{\circ}$F-32)$\times$$\frac{5}{9}. To convert to Kelvin, we use the formula K=(^{\circ}F+460)\times$$\frac{5}{9}$. When you use both these formulas with 400 $^{\circ}$F, you get 204 $^{\circ}$C and 478 K
