Problem Statement

There are quite a number of temperature scales. For this task we will concentrate on four of the perhaps best-known ones: Kelvin, Celsius, Fahrenheit, and Rankine. The Celsius and Kelvin scales have the same magnitude, but different null points. The Fahrenheit and Rankine scales also have the same magnitude, but different null points. The Celsius/Kelvin and Fahrenheit/Rankine scales have a ratio of 5 : 9.

Write code that accepts a value of kelvin, converts it to values of the three other scales, and prints the result.

Let's start with the solution:

convert_Kelvin <- function(K){
    if (!is.numeric(K)) 
      stop("\n Input has to be numeric")
    
    return(list(
      Kelvin = K,
      Celsius = K - 273.15,
      Fahreneit = K * 1.8 - 459.67,
      Rankine = K * 1.8  
    ))
    
  }
  
  convert_Kelvin(21)
