Which part of it, the JavaScript?

This is a JavaScript and HTML code. The JavaScript code has a function that converts temperature from Fahrenheit to Celsius then the result of the operation is inserted into the HTML page.

Pick up a JavaScript book then.
Try JavaScript novice to ninja by Darren . Google it sha
The JavaScript part is just a simple function to convert temperatures.
The function is declared and then called and the result is put into a paragraph which we grab hold of with its given Id in this case called "demo".
The innerHTML is an inbuilt property used to insert text to html tags like the paragraph in this case .It can also be used to insert html elements by their tag.
Now go and study JavaScript.

you have called your as an event into the function.

so you have to create an input field that carries that event (f). Then create a button that calls the function itself. so as to convert from Fahrenheit to Celsius.

But what your does basically is to convert from one degree to another. And displays the result in the p element.
