# C++ Program to Convert Celsius to Fahrenheit

In this post, we will learn how to convert Celsius to Fahrenheit using the C++ Programming language.

The below program asks the user to enter the temperature in degree Celsius, then it converts the temperature into degree Fahrenheit using the formula: F = (C x 9/5) + 32, where C is the temperature in degree Celsius.

So, without further ado, let’s begin this tutorial.

## C++ Program to Convert Celsius to Fahrenheit

```// C++ Program to Convert Celsius to Fahrenheit
#include <iostream>
using namespace std;

int main(){
float celsius, fahrenheit;

cout << "Enter the temperature in Celsius: ";
cin >> celsius;

// Celsius to fahrenheit
fahrenheit = (celsius * 9.0) / 5.0 + 32;

// Display result
cout << "The temperature in degree Fahrenheit: " << fahrenheit << endl;

return 0;
}
```

Output

``````Enter the temperature in Celsius: 40.6
The temperature in degree Fahrenheit: 105.08
``````

## How Does This Program Work?

```    float celsius, fahrenheit;
```

In this program, we have declared two floating data type variables named celsius and fahrenheit.

```    // Asking for input
cout << "Enter the temperature in Celsius: ";
cin >> celsius;
```

Then, the user is asked to enter the temperature in degree Celsius.

```    // Celsius to fahrenheit
fahrenheit = (celsius * 9.0) / 5.0 + 32;
```

The temperature is converted from degree Celsius to degree Fahrenheit using the conversion formula: F = (C x 9/5) + 32.

```    // Display result
cout << "The temperature in degree Fahrenheit: " << fahrenheit << endl;
```

Finally, the equivalent temperature in degree Fahrenheit is printed on the screen using the cout statement.
