Java Program for Temperature Unit Conversions

Java Program for Temperature Fahrenheit To Celsius Conversion

This java program is used to convert the temperature from Fahrenheit to Celsius scale.

Temperature in Celsius = ((Temperature in Fahrenheit - 32)*5)/9

import java.util.Scanner;	

public class FahrenheitToCelsius {

	public static void main(String args[]) {
	  Scanner in = new Scanner(System.in); 
	  System.out.println("Temparature Fahrenheit to Celsius Conversion");
	  System.out.println("---------------------------------------------");
	  System.out.print("Temperature in Fahrenheit: ");
	  int temperatureFh = in.nextInt();
	  float temperatureCs = (((float)temperatureFh-32)*5)/9;
	  
	  System.out.println("Temperature in Celsius ("+temperatureFh+" Fh): "+ temperatureCs);
	}
 }

Temperature in Celsius (100 Fh): 37.77778

Java Program for Temperature Celsius To Fahrenheit Conversion

This java program is used to convert the temperature from Celsius to Fahrenheit scale.

Temperature in Fahrenheit = ((9*Temperature in Celsius)/5)+35

import java.util.Scanner;	

public class CelsiusToFahrenheit {

	public static void main(String args[]) {
	  Scanner in = new Scanner(System.in); 
	  System.out.println("Temparature Celsius to Fahrenheit Conversion");
	  System.out.println("---------------------------------------------");
	  System.out.print("Temperature in Fahrenheit: ");
	  float temperatureCs = in.nextFloat();
	  float temperatureFh = (9*temperatureCs/5)+32;
	  
	  System.out.println("Temperature in Fahrenheit ("+temperatureCs+" Celsius): "+ temperatureFh);
	}
 }
