To convert a temperature from Kelvin to Fahrenheit, you need to follow these steps:
1. Convert Kelvin to Celsius:
Use the formula:
[tex]\[
\text{{Temperature in Celsius}} = \text{{Temperature in Kelvin}} - 273.15
\][/tex]
Given the temperature is 244 Kelvin:
[tex]\[
\text{{Temperature in Celsius}} = 244 - 273.15 = -29.15 \, \text{{Celsius}}
\][/tex]
2. Convert Celsius to Fahrenheit:
Use the formula:
[tex]\[
\text{{Temperature in Fahrenheit}} = \left(\text{{Temperature in Celsius}} \times \frac{9}{5}\right) + 32
\][/tex]
Substituting the temperature in Celsius:
[tex]\[
\text{{Temperature in Fahrenheit}} = \left(-29.15 \times \frac{9}{5}\right) + 32 = -20.47 \, \text{{Fahrenheit}}
\][/tex]
3. Round the result to the nearest whole number:
The temperature in Fahrenheit rounded to the nearest whole number is:
[tex]\[
-20
\][/tex]
So, the temperature of 244 Kelvin converted to Fahrenheit, rounded to the nearest whole number, is [tex]\(\mathbf{-20}\)[/tex].
