Convert Celsius into Fahrenheit in Java Program | Function

Convert celsius into fahrenheit in Java program.

In this article, you will learn how to convert celsius into fahrenheit in Java program.

Example

Standard Formula

You should have knowledge of the following topics in Java programming to understand this program:

• Java java.util.Scanner package
• Java main() method
• Java System.out.println() function

Source Code

// Convert Celsius into Fahrenheit in Java Program
import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
    	Scanner in = new Scanner(System.in);

        System.out.println("Enter the temperature in Celsius::\n");
        float c = in.nextFloat();
        float f;
        // c = celsius, f = fahrenheit

        // It will convert the celsius into fahrenheit
        f = (float)((c * 9 / 5) + 32);

        // It will print the final output
        System.out.println(c + " Celsius = " + f + " Fahrenheit");
    }
}

Run

Output

Explanation

In this given program, we have taken input 36 from the user via the system console. Then we applied this standard formula F = (C * 9 / 5) + 32 to make calculations.

Then this program will print the final output 44.6 Fahrenheit.

Convert Celsius into Fahrenheit in Java Program using Function

// Convert Celsius into Fahrenheit in Java Program using Function
import java.util.Scanner;

public class Main {
    // This function will convert the celsius into fahrenheit
    public static float CelcToFahren(float x) {
        return (float)((x * 9 / 5) + 32);
    }
    
    // It's the driver function
    public static void main(String[] args) {
    	Scanner in = new Scanner(System.in);

        System.out.println("Enter the temperature in Celsius::\n");
        float c = in.nextFloat(); // c = celsius

        // It will print the final output
        System.out.println(c + " Celsius = " + CelcToFahren(c) + " Fahrenheit");
    }
}
