Background:

input: Requests user input $($Example: value$=$input$(\text{'}$Enter a value: $\text{'}))$ Use "doc input" to learn more about how to use this function.

Problem Statement:

Design a MATLAB program that reads an input temperature in Fahrenheit and converts it to an absolute temperature in kelvin, and writes out the result.

$K=\frac{5}{9}**(F-32)+273$

Our program must perform the following steps:

Prompt the user to enter an input temperature in $F.($Hint: Check background section above$).($F$=$input$(\text{'}$Enter the temperature in degrees Fahrenheit: $\text{'})$

Read the input temperature. $($ use the example values as inputs and take tow screenshots$).$

Calculate the temperature in kelvin from the above equation.

Write out the result.

Example Outputs:

$$ temp$\_$conversion

Enter the temperature in degrees Fahrenheit: $212$

$212\mathrm{.}00$ degrees Fahrenheit $=373\mathrm{.}15$ kelvin.

$$ temp$\_$conversion

Enter the temperature in degrees Fahrenheit: $-110$

$-110\mathrm{.}00$ degrees Fahrenheit $=194\mathrm{.}26$ kelvin.
