How to convert fahrenheit to celsius in C#

Answer 1

using System;

class Program
{
    static double FahrenheitToCelsius(double f) {
        double t;
 
        t = (f - 32) * (5.0 / 9.0);
 
        return t;
    }
    static void Main() {
        try {
            Console.Write("Enter Temperature in Fahrenheit: ");
            double temp_f = Convert.ToDouble(Console.ReadLine());
            double temp_c = FahrenheitToCelsius(temp_f);
            Console.WriteLine("{0:F2} Fahrenheit = {1:F2} Celsius\n", temp_f, temp_c);
        }
        catch (Exception ex) {
            Console.WriteLine(ex.Message);
        }
    }
}





/*
run:
    
Enter Temperature in Fahrenheit: 1
1.00 Fahrenheit = -17.22 Celsius
 
Enter Temperature in Fahrenheit: 50
50.00 Fahrenheit = 10.00 Celsius
