title: Convert Celsius to Fahrenheit
---
 Remember to use **`Read-Search-Ask`** if you get stuck. Try to pair program  and write your own code 
###  Problem Explanation:
The algorithm to convert from Celsius to Fahrenheit is the temperature in Celsius times `9/5`, plus `32`.
You are given a variable **celsius** representing a temperature in Celsius. Use the variable **fahrenheit** already defined and apply the algorithm to assign it the corresponding temperature in Fahrenheit.

##  Hint: 1
Take a look at the code. There is an area that you're not supposed to edit. From there, ask yourself - what is used there that I haven't seen before?

##  Hint: 2
Keep in mind the **order of operation** check the link in the _links_ section for more information.

## Spoiler Alert!
**Solution ahead!**
##  Basic Code Solution:
```javascript
function convertToF(celsius) {
// Only change code below this line
var fahrenheit = (celsius * (9/5)) + 32;
// Only change code above this line
if ( typeof fahrenheit !== 'undefined' ) {
return fahrenheit;
} else {
return 'fahrenheit not defined';
}
}
// Change the inputs below to test your code
convertToF(30);
```
### Code Explanation:
* Declare the **fahrenheit** variable.
* Make sure the proper order of arithmetic operations is followed by using parenthesis (`()`) when needed.
##  NOTES FOR CONTRIBUTIONS:
*  **DO NOT** add solutions that are similar to any existing solutions. If you think it is **_similar but better_**, then try to merge (or replace) the existing similar solution.
* Add an explanation of your solution.
* Categorize the solution in one of the following categories — **Basic**, **Intermediate** and **Advanced**. 
* Please add your username only if you have added any **relevant main contents**. ( **_DO NOT_** _remove any existing usernames_)
