The formula for converting a temperature from Fahrenheit to

The formula for converting a temperature from Fahrenheit to Celsius is C =5/9(F - 32) where F is the Fahrenheit temperature. Write a function named celsius that accept a Fahrenheit temperature as an argument. The function should return the temperature, converted to Celsius. Demonstrate the function by calling it in a loop that display a table of the Fahrenheit temperature 0 through 20 and their Celsius equivalents.

Solution

Temp.java

import java.text.DecimalFormat;
import java.util.Scanner;

public class Temp {

  
   public static void main(String[] args) {
       DecimalFormat df = new DecimalFormat(\"0.00\");
       for(double i=0; i<=20; i++){
       double celsius = celsius (i);
       System.out.println(\"Fahrenheit Temparature: \"+i+\" Celsius Temparature: \"+df.format(celsius));
       }
   }
   public static double celsius (double fahrenheit){
       double celsius = ( 5 /(double) 9 ) * ( fahrenheit - 32 );
       return celsius;
    }

}

Output:

Fahrenheit Temparature: 0.0 Celsius Temparature: -17.78
