Here is a Java program 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.
where, F is temperature in fahrenheit and C is temperature in celsius.
Java program to convert fahrenheit to celsius temperature
package com.tcc.java.programs;
import java.util.Scanner;
public class FahrenToCelcius {
public static void main(String args[]) {
float celsius, fahren;
Scanner scanner;
scanner = new Scanner(System.in);
// 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);
}
}
Output
Enter Temperature in Fahrenheit 32 Temperature in Celsius = 0.0
Enter Temperature in Fahrenheit 100 Temperature in Celsius = 37.77778
