# Java Program to Convert Celsius into Fahrenheit

• Last Updated : 24 Nov, 2020

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`

Time Complexity: O(1)

Space Complexity: O(1)
