C Program for Fahrenheit to Kelvin conversion

The below program ask the user to enter the temperature in Fahrenheit. After getting the temperature in Fahrenheit from the user program convert it in Kelvin.

#include <stdio.h>
float convertFahKelvin(float F )
{
    return 273.5 + ((F - 32.0) * (5.0/9.0));
}
int main()
{
    float kelvin, fahrenheit;
    printf("Enter temperature in fahrenheit: ");
    scanf("%f", &fahrenheit);
    //called function to convert fahrenheit to kelvin
    kelvin = convertFahKelvin(fahrenheit);
    printf("%.2f Fahrenheit = %.2f Kelvin",fahrenheit,kelvin);
    return 0;
}

Output:

Enter temperature in Fahrenheit: 100
100.00 Fahrenheit = 311.28 Kelvin
