C Program To Convert Temperature From Celsius To Fahrenheit And Fahrenheit To Celsius

In this article, we are going to write a c program to Convert Temperature From Celsius To Fahrenheit And Fahrenheit To Celsius.

first, we will convert Celsius to Fahrenheit and in the second we will convert Fahrenheit to Celsius. But first of all, you need to know what is Celsius and Fahrenheit and what is its formula.

Introduction About Celsius And Fahrenheit

Celsius is represented by ^oC and Fahrenheit is represented by ^oF. There is a formula to convert Celsius to Fahrenheit, using which we will be able to convert Celsius to Fahrenheit.

Similarly, there is also a formula to convert Fahrenheit to Celsius, using which we will be able to convert Fahrenheit to Celsius.

Formula to Convert Temperature From Celsius To Fahrenheit

Fahrenheit = (celsius * 1.8) + 32

Formula to Convert Temperature From Fahrenheit to Celsius

Celsius = ((Fahrenheit-32)*5)/9;

Now without wasting time let’s start programming.
