Hourly rate and currency

Hello,
I'm a new user so I might ask trivial questions that could be because they have answers on the page.

How can I calculate a rate per hour worked and not by task. For example, if I worked an hour and a half and the pay is $ 10 an hour.
Can I change the currency from a dollar to another currency?

I'm sorry, I didn't understand that question.
