# Exercise 07 - tempConversion
|
|
|
|
Write two functions that convert temperatures from Fahrenheit to Celsius, and vice versa:
|
|
```
|
|
ftoc(32) // fahrenheit to celsius, should return 0
|
|
|
|
ctof(0) // celsius to fahrenheit, should return 32
|
|
```
|
|
|
|
Because we are human, we want the result temperature to be rounded to one decimal place: i.e., `ftoc(100)` should return `37.8` and not `37.77777777777778`.
|
|
|
|
This exercise asks you to create more than one function so the `module.exports` section of the spec file looks a little different this time. Nothing to worry about, we're just packaging both functions into a single object to be exported.

## Hints
|
|
- You can find the relevant formulae on [Wikipedia](https://en.wikipedia.org/wiki/Conversion_of_units_of_temperature).
|
|
|
|
- Try to find by yourself on the Internet how to round a number to 1 decimal place in JavaScript. If you struggle, have a look [here](https://stackoverflow.com/q/7342957/5433628).
