Java program to convert celsius to fahrenheit – Java Program to Convert Celsius to Fahrenheit

Java program to convert celsius to fahrenheit: Practice Java programming from home without using any fancy software just by tapping on this Simple Java Programs for Beginners tutorial.

Java Program to Convert Celsius to Fahrenheit

• Java program to convert temperature from Celsius to Fahrenheit.
• Write a java program to convert temperature from Celsius to Fahrenheit.

In this java program, we have to convert celsius temperature to fahrenheit temperature scale. We will first take a celsius temperature as input from user and then convert it to fahrenheit temperature and print it on screen.

For Example,
40 Celsius is equal to 104 Fahrenheit

• Celsius is a temperature scale where 0 °C indicates the melting point of ice and 100 °C indicates the steam point of water.
• Fahrenheit temperature scale was introduced around 300 years ago and is currently used in US. The boiling point of water is 212 °F and the freezing point of water is 32 °F.

Given a temperature in celsius, we can convert to fahrenheit scale using following equation.

F =(9/5)*C + 32
where, C is the temperature in Celsius and F is temperature in Fahrenheit.

Java program to convert celsius to fahrenheit temperature

package com.tcc.java.programs;
 
import java.util.Scanner;
 
/**
 * Java Program to convert temperature from 
 * Celsius to Fahrenheit
 */
public class CelsiusToFahrenheit {
    public static void main(String args[]) {
        double celsius, fahren;
        Scanner scanner;
        scanner = new Scanner(System.in);
        // Take temperature in Celsius as input from user
        System.out.println("Enter Temperature in Celsius");
        celsius = scanner.nextFloat();
 
        fahren = (9.0 / 5.0) * celsius + 32;
 
        System.out.print("Temperature in Fahrenheit = " + fahren);
    }
}

Output

Enter Temperature in Celsius
100
Temperature in Fahrenheit = 212.0

Enter Temperature in Celsius
0
Temperature in Fahrenheit = 32.0
