French language Q&A Forum

Why does Kwiziq (and some other apps that teach French) make use of "livre" (meaning "pound") in their examples. I have seen it used for both weight and money. France and Canada use it for neither. The US use it for weight but are there any countries that use it for money any longer.

Is it just so we can read historical novels set in English-speaking countries? If so I would not expect to see it used so often when there must be many more useful vocab words that we could be encouraged to memorize.

Instead of Ça vous va ? would you say Ça vous êtes? Thank you
