Java Program to Convert Celsius into Fahrenheit

Celsius scale is a temperature scale that is based on the freezing point of water at 0 °C and the boiling point of water at 100 °C. Fahrenheit scale is a temperature scale that has a freezing point of water at 32 °F and the boiling point of water at 212 °F.

Examples:

Input : 0
Output: 32
Input :-40
Output:-40

 fahrenheit=(celsius*1.8)+32

Approach:

1. Initializing value of celsius as 10.0 and Fahrenheit value as 0.0
2. Calculate the Fahrenheit using the below formula
3. Fahrenheit=(celsius*1.8)+32;
4. Display Fahrenheit.

Below is the implementation of the above approach:

Java

// Java Program to Convert Celsius into Fahrenheit
class celsiustofahrenheit {
    public static void main(String[] args)
    {
        // initialising
        double celsius = 10.0, fahrenheit = 0.0;

        // formula for conversion
        fahrenheit = (celsius * 1.8) + 32;
        System.out.println(
            " value of temperature in fahrenheit:"
            + fahrenheit);
    }
}

Output

 value of temperature in fahrenheit:50.0
