# C Program to Convert Celsius to Fahrenheit

Last Updated on April 13, 2023 by Prepbytes Temperature conversion is a common requirement in many programming applications. One of the most common conversions is Celsius to Fahrenheit, and it is a fundamental concept in the field of thermodynamics. In this article, we will deep dive and discuss the c program to convert Celsius to Fahrenheit. Converting Celsius to Fahrenheit temperature requires mathematical operations to perform which will enhance your understanding and logical thinking. Let’s see how to code the C program to convert Celsius to Fahrenheit.

## How to Convert Celsius to Fahrenheit

With the advance of science and technology, we now have the knowledge for converting one temperature unit to another temperature unit. In the programming world, we can convert Celsius to Fahrenheit by simply performing some mathematical operations.

Formula to convert Celsius to Fahrenheit in C
Here we have Celsius to fahrenheit formula in C

``Fahrenheit Temperature = (1.8 * celsius) + 32;``

## Algorithm for C Program to Convert Celsius to Fahrenheit

1. Define temperature in Celsius units.
2. Apply in the formula Fahrenheit = (1.8 * celsius) + 32.
3. Print the temperature in Fahrenheit.

## Code Implementation for C Program to Convert Celsius to Fahrenheit

```#include<stdio.h>
#include<conio.h>

void main()
{
float celsius,fahrenheit;
clrscr();

printf("\n Enter the Temparature in Celsius : ");
scanf("%f",&celsius);

fahrenheit = (1.8 * celsius) + 32;
printf("\n Temperature in Fahrenheit : %f ",fahrenheit);

getch();
}
```

Explanation for C Program to Convert Celsius to Fahrenheit
This is a C program that prompts the user to enter a temperature value in Celsius, converts it to Fahrenheit using the conversion formula Fahrenheit = (Celsius * 1.8) + 32, and displays the result to the console. It uses the scanf() function to read the user input and the printf() function to display the result. The clrscr() and getch() functions are used to clear the screen and wait for the user to press a key before exiting the program.

Time Complexity for C Program to Convert Celsius to Fahrenheit
O(1) will be the time complexity as we are performing some scientific calculations which do not require any loop or recursion for the c program to convert Celsius to Fahrenheit temperature.

Conclusion
In this blog, we have discussed the c program to convert Celsius to Fahrenheit. For solving big problems, you have to master logical problems like converting Celsius to Fahrenheit which will increase your logical thinking and also brush up your hands on the coding language. Practice more problems to conquer your dreams. we have learned how to write a C program to convert Celsius to Fahrenheit. We have also reviewed the Celsius to Fahrenheit formula in c conversion and explained each step of the program. With this basic understanding of C programming, you can now create more complex applications that involve temperature conversions, such as weather monitoring systems, temperature control systems, and more.

Here we have FAQs on the C program to convert Celsius to fahrenheit

Q1: What is the formula used to convert Celsius to Fahrenheit?
Ans: The formula to convert Celsius to Fahrenheit is: Fahrenheit = (Celsius * 1.8) + 32.

Q2: What is the data type of the Celsius and Fahrenheit variables in this program?
Ans: The Celsius and Fahrenheit variables are declared as float data type.

Q3: Why is the clrscr() function used in this program?
Ans: The clrscr() function is used to clear the screen before displaying the converted temperature value.

Q4: What happens if the user enters a non-numeric value for the temperature input?
Ans: If the user enters a non-numeric value for the temperature input, the program will not be able to convert it to Fahrenheit, and the output will be unpredictable. It is best practice to handle such input errors by validating user input using techniques such as input data type checking and input range validation.
