C++ program to convert Celsius into Fahrenheit

In this tutorial, we will discuss the concept of the C++ program to convert Celsius into Fahrenheit

In this post, we will learn how to write a program to convert Celsius into Fahrenheit using the scientific equations in C++ programming language with an Example program.

Temperature and conversion

Java program to convert Fahrenheit into Celsius — Conversion equation

Generally, We have known three types of temperature units Fahrenheit, Celsius, and Kelvin. In this article, we are discussing how to convert temperature units Celsius into Fahrenheit. Fahrenheit and Celsius are the measuring units in degrees as ⁰F and ⁰C respectively.

Scientific equation Fahrenheit= Celsius*9/5+32

Code to Convert Celsius into Fahrenheit

Convert Celsius into Fahrenheit

In this program, the user declares and initializes a double variable Celsius as 30.0. It will be converted into Fahrenheit, by the scientific equation using the C++ programming language.

Program 1

//C++ program to convert C into f
#include <iostream>
using namespace std;
int main() {
    float celsius, fahrenheit;
    // variable declaration
    // variable initiation
    celsius=36.9;
    //Calculate fahrenheit
    fahrenheit=(celsius * 9/5)+32;
    cout<<celsius<<" Celsius is: "<<fahrenheit <<" Fahrenheit";
    //display result on the screen

    return 0;
}

When the above code is executed, it produces the following result

36.9 Celsius is: 98.42 Fahrenheit

Convert Celsius into Fahrenheit – Entered by the user

In this program, the user declares the variable as Double for Celsius and Fahrenheit, then the user is asked to enter a double value to Celsius. It will be converted into Fahrenheit, by the scientific equation using the C++ programming language

Program 2

//C++ program to convert C into f from user input
#include <iostream>
using namespace std;
int main() {
    float celsius, fahrenheit;
    // variable declaration
    // ask input from the user
    cout<<"Enter the temperature in Celsius:";
    cin>>celsius;//reading the input
    //Calculate fahrenheit
    fahrenheit=(celsius * 9/5)+32;
    cout<<celsius<<" Celsius is: "<<fahrenheit <<" Fahrenheit";
    //display result on the screen

    return 0;
}

When the above code is executed, it produces the following result

Enter the temperature in Celsius:99.99
99.99 Celsius is: 211.982 Fahrenheit
