This tutorial entitled “Convert Fahrenheit to Celsius in Java” will teach you on converting Fahrenheit to Celsius based on user input.
At this time, we are using a float variable for temperature and use a scanner for user input. Please follow all the steps to complete this java tutorial.
Convert Fahrenheit to Celsius in Java Steps
1. Create a new class and name it what you want.

2. Above your Main Class, Insert an import code to access the Scanner library.
[java]import java.util.Scanner;[/java]3. Declare a scanner and two variables inside your main method.
[java]Scanner input = new Scanner(System.in);
float temper;
float result;[/java]4. After step 3, insert the code below for user input.
[java]System.out.print("Enter Fahrenheit Temperature: ");
temper = input.nextFloat();[/java]5. After step 4, insert the code below for the algorithm and output.
[java]result = (temper - 32) * 5 / 9;
System.out.println("Temperature in Celsius: " + result);[/java]6. Run your program and the output should look like the image below.

7. Complete Source Code.
[java]import java.util.Scanner;
public class FahrenheitToCelsius {
public static void main(String args[]){
Scanner input = new Scanner(System.in);
float temper;
float result;
System.out.print("Enter Fahrenheit Temperature: ");
temper = input.nextFloat();
result = (temper - 32) * 5 / 9;
System.out.println("Temperature in Celsius: " + result);
}

Frequently Asked Questions
How does this Java project work?
Built with Java Swing (NetBeans IDE) and MySQL backend via JDBC. Standard structure: JFrame designer to event handlers to DAO layer to MySQL. Login form for auth. Ready to extend for BSIT capstone scope.
What Java JDK and MySQL versions does this project require?
Most projects in this batch use Java JDK 8 or 11 with MySQL 5.7+ or MariaDB 10+. To run: install JDK (Adoptium / Oracle), install MySQL Server + MySQL Workbench, install NetBeans IDE (15+ supports modern JDK), open the project (.zip extracted folder), right-click + Open Project, add MySQL JDBC driver to Project Libraries, run.
How do I set up the database for this Java project?
Open MySQL Workbench (or phpMyAdmin if you have XAMPP), create a new empty database with the name specified in the project. Import the included .sql file via Server, Data Import in Workbench (or Import tab in phpMyAdmin). Update the connection class (usually DBConnection.java or DatabaseConnection.java) with your MySQL host, port, username, password, and database name.
Can I use this Java project for a BSIT capstone or thesis?
Yes, Java is one of the most accepted languages by Philippine BSIT panels. Extend it: add role-based access (admin/staff/customer login redirect), JasperReports printable reports, dashboards with JFreeChart, audit log, multi-branch support. Pair with Chapter 1-5 documentation matching your panel’s rubric.
Why am I getting ‘ClassNotFoundException: com.mysql.jdbc.Driver’ or ‘No suitable driver’?
Three common Java JDBC issues: (1) MySQL JDBC driver JAR not added to project Libraries. Right-click Project, Properties, Libraries, Add JAR/Folder, select mysql-connector-java-X.X.X.jar. (2) Wrong driver class name. Modern (8.0+) uses com.mysql.cj.jdbc.Driver, legacy (5.x) uses com.mysql.jdbc.Driver. (3) Connection URL missing serverTimezone parameter, add ?serverTimezone=UTC to the URL.
Where can I find more Java projects with source code?
Browse the Java Projects hub for the full library (120+ Java desktop systems). For modern Java web alternatives consider Spring Boot. For other desktop stacks see VB.NET Projects or C# Projects. For BSIT capstone idea lists see 150 Best Capstone Project Ideas.
