Question

in java

Write a program that convert a Fahrenheit to Celsius. For conversion, use as many as methods you want

Answer 1

Below is the code to convert the Fahrenheit temperature to Celsius.

-----------------------------------------------------------------------------------------------

/*
* This program converts Fahrenheit temperature to Celsius temmperature.
* It asks for user input in Fahrenheit and displays the output in Celsius.
*/
import java.text.DecimalFormat;
import java.util.Scanner;

public class TemperatureConvert
{
    public static void main(String[] args)
    {
        Scanner s = new Scanner(System.in);
        System.out.print("Enter temperature in Fahrenheit:");
        double fahrenheit = s.nextDouble();
        double celsius = convertFhToCs(fahrenheit);
        //Uncomment below line if only 2 digits after the decimal format needs to be displayed.
        //celsius = Double.parseDouble(new DecimalFormat("##.##").format(celsius));
        System.out.println("Temperature in Celsius: "+celsius);
        s.close();
    }
  
    /*
     * Method to convert temperature from Fahrenheit to Celsius.
     * @param - double fh
     */
    public static double convertFhToCs(double fh)
    {
       //Below is the formula for converting fahrenheit temperature to Celsius temperature.
       double cs = (( 5 *(fh - 32.0)) / 9.0);
       return cs;
    }

}

Output:

The output in celsius displayed below. If you want to display only two digits after the decimal point, Please uncomment the line I kept at the line number17 and run the program.

Enter temperature in Fahrenheit:98
Temperature in Celsius:36.666666666666664
