As far as I can see your code can only throw an exception if the user enters an invalid temperature - something which isn't a number. The easiest way to prevent that is to use double.TryParse rather than double.Parse. This returns false if the string entered can't be parsed to a double and sets the variable passed to it as an output parameter to 0. public static class TempConverter { public static double CelsiusToFahrenheit(string TempCelsius) { double Celsius; bool success = double.TryParse(TempCelsius out Celsius); if(!success) Console.WriteLine(Invalid number using 0 instead); double Fahren = (Celsius*9/5) + 32; return Fahren; } public static double FahrenheitToCelsius(string TempFahren) { double Fahren; bool success = double.TryParse(TempFahren out Fahren); if(!success) Console.WriteLine(Invalid number using 0 instead); double Celsius = (Fahren - 32) * 5 / 9; return Celsius; } }
