This is not the metric system, but for a long time I wondered what a "quid" is. It's mentioned a lot on British shows. Finally, I googled it, and I gather it's the same thing as a pound. (But then you've got to do the math to figure out what that is in dollars.
I guess the quid thing is similar to the use of the word "buck" for an American dollar.
