Answer
$-62.22^{\circ}C$
$211 K$
Work Step by Step
Use the formula $(^{\circ}F - 32)\times\frac{5}{9}$ to convert from Fahrenheit to Celsius and simply add 273.15 to the Celsius to convert to Kelvin:
$(-80^{\circ}F - 32 )\times \frac{5}{9} = -62.22^{\circ}C$
$(-80^{\circ}F - 32 )\times \frac{5}{9} + 273.15 K= 211.928 K$
