Java Program to Convert Fahrenheit to Celsius

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

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

For Example,
80 Fahrenheit is equal to 26.6667 Celsius
  • 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.
  • Celsius is a temperature scale where 0 °C indicates the melting point of ice and 100 °C indicates the steam point of water.

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

C = (F - 32)*(5/9)

where, F is temperature in fahrenheit and C is temperature in celsius.

Java program to convert fahrenheit to celsius temperature


import java.util.Scanner;

 * Java Program to convert temperature from Fahrenheit to Celsius
public class FahrenToCelcius {
    public static void main(String args[]) {
        float celsius, fahren;
        Scanner scanner;
        scanner = new Scanner(;
        // Take fahrenheit temperature input from user
        System.out.println("Enter Temperature in Fahrenheit");
        fahren = scanner.nextFloat();

        celsius = 5 * (fahren - 32) / 9;

        System.out.print("Temperature in Celsius = " + celsius);
Enter Temperature in Fahrenheit
Temperature in Celsius = 0.0
Enter Temperature in Fahrenheit
Temperature in Celsius = 37.77778
