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
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
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
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
