## How to convert temperature from Celsius to Fahrenheit

Before we write logic in Java program, let us learn how we can convert Celsius to Fahrenheit mathematically.
We know Celsius is equal to 32° Fahrenheit.

Equation to convert temperature from Celsius to Fahrenheit is given by: ``F = C * (9/5) + 32``

or

``F = C * 1.8 + 32``

Here, C is temperature in Celsius.

## Program to convert Celsius to Fahrenheit

``````/**
* Java program to convert temperature from Celsius to Fahrenheit.
*/
import java.util.Scanner;

public class TemperatureConverter {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

/* Input temperature in Celsius from user */
System.out.print("Enter temperature in Celsius: ");
float C = in.nextFloat();

/* Convert Celsius to Fahrenheit */
float F = C * (9f / 5) + 32;

/* Print result */
System.out.println(C + " degree Celsius is equal to " + F +" degree Fahrenheit.");

}
}``````

Output

```Enter temperature in Celsius: 28.5
28.5 degree Celsius is equal to 83.3 degree Fahrenheit.```
