C++ program to convert the temperature from Fahrenheit to Kelvin using class

Submitted by Shubh Pachori, on September 05, 2022

Problem statement

Given temperature in Fahrenheit, we have change it to Kelvin using the class and object approach.

Example:

Input:
Enter Temperature in Fahrenheit: 100

Output:
Temperature in Kelvin : 310.928

C++ code to convert the temperature from Fahrenheit to Kelvin using the class and object approach

#include <iostream>
using namespace std;

// create a class
class FahrenheitToKelvin {
  // private data member
 private:
  float fahrenheit;

  // public functions
 public:
  // getTemperature() function to 
  // get the Temperature
  void getTemperature() {
    cout << "Enter Temperature in Fahrenheit: ";
    cin >> fahrenheit;
  }

  // FToK() function to convert the temperature
  double FToK() {
    // initialising float type variables 
    // to perform operations
    float kelvin;

    kelvin = (5.0 / 9) * (fahrenheit - 32) + 273.15;

    // returning the converted temperature
    return kelvin;
  }
};

int main() {
  // create a object
  FahrenheitToKelvin F;

  // float type variable to store the 
  // converted temperature
  float temperature;

  // function is called by the object to 
  // store the temperature
  F.getTemperature();

  // FToK() function to convert 
  // the temperature
  temperature = F.FToK();

  cout << "Temperature in Kelvin: " << temperature;

  return 0;
}

Output

Enter Temperature in Fahrenheit: 123
Temperature in Kelvin : 323.706

Explanation

In the above code, we have created a class FahrenheitToKelvin, one float type data member Fahrenheit to store the temperature in Fahrenheit, and public member functions getTemperature() and FToK() to store and convert the given temperature.

In the main() function, we are creating an object F of class FahrenheitToKelvin, reading the temperature by the user using the function getTemperature(), and finally calling the FToK() member function to convert the given temperature from Fahrenheit to kelvin. The FToK() function contains the logic to convert the given temperature from Fahrenheit to kelvin and printing the result.
