public static void main(String[] args) {

Scanner sc=new Scanner(System.in);

System.out.println("Temperature in Celcius?");

double c=sc.nextDouble();

double f=((9*c)/5)+32;

System.out.println("Converting to Fahrenheit...");

System.out.println(c+"°C="+f+"°F");

}

}

Variable Description:-

1. c:- To accept temperature as input
2. f:- To calculate and store temperature in Fahrenheit

Answer 2

import java.util.Scanner;  

public class CelsiusToFahrenheit {

   public static void main(String[ ] args) {

       System.out.print("Celsius - ");

       double celsius = new Scanner(System.in).nextDouble( );

       System.out.printf("%.3f °C = %.3f °F", celsius, ((celsius * 9) / 5) + 32);

   }

}

Sample I/O:

Celsius - 24

24.000 °C = 75.200 °F
