I can't think of a good tip for doing it in your head, but if you have a smart phone with you, it shouldn't be too difficult. If you go soon, you'll be getting a fairly good deal since the dollar has been getting stronger. Today's exchange rate is 1 euro to about 1.11 U.S. dollars. That's better than it's been in quite a while. A few years back 1 euro was equal to about $1.45.
