Java program to convert celsius to fahrenheit

In this article, you will learn the Java program to convert units of measurement from Celsius to Fahrenheit and vice versa. Such a type of program plays an important role in most scientific applications, as it is the most widely used temperature scale throughout the world. The Fahrenheit scale is mostly used in the United States.

The boiling point of water is 100°C and the freezing point is 0°C on the Celsius scale, while the boiling point of water is 212°F and the freezing point is 32°F on the Fahrenheit scale. 

Celsius to Fahrenheit

To convert temperatures in degrees Celsius to Fahrenheit, multiply by 1.8 (or 9/5) and add 32.

celsius * 1.8 = fahrenheit - 32

Algorithm

1. Take temperature input from the user or define temperature in a Celsius unit.
2. Apply the above formula to convert Celsius to Fahrenheit.
3. Print the value in Fahrenheit.

Java program to convert Celsius to Fahrenheit

Here is a simple program to convert Celsius to Fahrenheit using the Java programming.

public class celsiustofahrenheit {
    public static void main(String[] args)
    {
        // initialising variables
        double celsius = 10.0, fahrenheit = 0.0;
        
        // convert from celsius to fahrenheit
        fahrenheit = (celsius * 1.8) + 32;
        System.out.println(
            " Temperature in Fahrenheit : "
            + fahrenheit);
    }
}

Temperature in Fahrenheit : 50.0
