Program for Fahrenheit to Celsius conversion in C

Given with temperature ‘n’ in Fahrenheit and the challenge is to convert the given temperature to Celsius and display it.

Example

Input 1-: 132.00 Output -: after converting fahrenheit 132.00 to celsius 55.56 Input 2-: 456.10 Output -: after converting fahrenheit 456.10 to celsius 235.61

For converting the temperature from Fahrenheit to Celsius, there is a formula which is given below

T(°C) = (T(°F) - 32) × 5/9

Where, T(°C) is temperature in Celsius and T(°F) is temperature in Fahrenheit

Approach used below is as follows −

• Input temperature in a float variable let’s say Fahrenheit
• Apply the formula to convert the temperature into Celsius
• Print celsius

Algorithm

Start Step 1-> Declare function to convert Fahrenheit to Celsius    float convert(float fahrenheit)       declare float Celsius       Set celsius = (fahrenheit - 32) * 5 / 9       return Celsius step 2-> In main()    declare and set float fahrenheit = 132.00    Call convert(fahrenheit) Stop

Example

 Live Demo

#include <stdio.h> //convert fahrenheit to celsius float convert(float fahrenheit) {    float celsius;    celsius = (fahrenheit - 32) * 5 / 9;    return celsius; } int main() {    float fahrenheit = 132.00;    printf("after converting fahrenheit %.2f to celsius %.2f ",fahrenheit,convert(fahrenheit));    return 0; }

Output

IF WE RUN THE ABOVE CODE IT WILL GENERATE FOLLOWING OUTPUT

after converting fahrenheit 132.00 to celsius 55.56
