convert fahrenheit to celsius

To convert Fahrenheit to Celsius in the C programming language, you can use the following formula:

Celsius = (Fahrenheit - 32) * 5/9

Here's a step-by-step explanation of the formula:

1. Subtract 32 from the Fahrenheit temperature. This step is necessary because the Fahrenheit scale starts at 32 degrees, while the Celsius scale starts at 0 degrees.
2. Multiply the result by 5/9. This step converts the temperature from Fahrenheit to Celsius by scaling it down to the appropriate ratio.

Here's an example code snippet that demonstrates the conversion:

#include <stdio.h>

int main() {
    float fahrenheit, celsius;

    printf("Enter the temperature in Fahrenheit: ");
    scanf("%f", &fahrenheit);

    celsius = (fahrenheit - 32) * 5 / 9;

    printf("The temperature in Celsius is: %.2f\n", celsius);

    return 0;
}

In this code, the user is prompted to enter the temperature in Fahrenheit. The value is then stored in the fahrenheit variable. The conversion is performed using the formula explained earlier, and the result is stored in the celsius variable. Finally, the converted temperature is printed to the console using printf.
