Can anyone share with me the simple mental math process of converting euros to dollars? Thanks so much!

There are online convertors. Try www.oanda.com

Well, it depends on the exchange rate the day you're doing a transaction, but for the last year or so I've generally figured everything in euros costs about one-third again as much as it does in dollars. So if something is 1 euro it costs me $1.33.

One euro = One dollar Thirty four cents, as of May 23, 2007, so add roughly one-third to the dollar to get euro.

I don't know whether this is what you mean. But when I was in Europe in March the Euro was worth about $1.31. So when I wanted to roughly figure the cost in dollars I just added a third to the cost in Euro.

Thanks everyone. We leave tomorrow and I wanted a quick way to figure it out.

If you're doing the mental math, fake it like you would for a tip.

Move the decimal point one place to the left, multiply by three (to get the extra 30 percent) and tack it on.

Ex. Euro 23.30
2.330 x 3 = (about)7.00
$30.00

It's rough, but if you're just trying to make sure that you don't go over budget or start getting declined credit cards, it'll be close enough.

Or sometimes it's easier to figure out when you say that 3€ equals $4. So if something is 30€ it's $40, 60€=$80, 120€=$160 etc.

What I do before I go is to access www.oanda.com and print out the FXCheatSheet (under Currency Tools). I print both Euro to USD and USD to Euro. I tape them to an index card and carry it with me. I can usually memorize the common amounts, like the equivalent of $20, $50, $100, but it is nice to have the card. I know the exchange rate can change from day to day, but this works for me.

Just spent 3 weeks there and the ATMs 1.36-1.37 USD per Euro (a USD is $0.7325 Euro - nearly the interbank rate.
Everything is way expensive.

Easiest:

Multiply your dollars by 8 and drop a zero.

$30x8/10=24€

Close enough

I don't think about it.

Just jesting, like a previous poster, I add a third. For example, if a Coke Lite is 1 euro, I think $1.30
