Temperature conversion formula
Formula to convert temperature from degree fahrenheit to degree celsius is given by -
Logic to convert temperature from fahrenheit to celsius
Step by step descriptive logic to convert temperature from degree fahrenheit to degree celsius -
- Read temperature in fahrenheit in some variable say fahrenheit.
- Apply the temperature conversion formula celsius = (fahrenheit - 32) * 5 / 9.
- Print the value of celsius.
Program to convert temperature from fahrenheit to celsius
/**
* C program to convert temperature from degree fahrenheit to celsius
*/
#include <stdio.h>
int main()
{
float celsius, fahrenheit;
// Reads temperature in fahrenheit
printf("Enter temperature in Fahrenheit: ");
scanf("%f", &fahrenheit);
// Fahrenheit to celsius conversion formula
celsius = (fahrenheit - 32) * 5 / 9;
// Print the result
printf("%.2f Fahrenheit = %.2f Celsius", fahrenheit, celsius);
return 0;
}
Note: %.2f is used to print fractional values only up to two decimal places. You can also use %f to print fractional values normally up to six decimal places.
Output
Enter temperature in Fahrenheit: 205 205.00 Fahrenheit = 96.11 Celsius
Happy coding ;)
