Does euro cost more than us dollars?

1 euro is 1.48 US dollars as of October 2009.

You need a higher number on the US money than on the euro money.

Not exactly ...One currency doesn't "cost more" than another because that would imply there's some third currency that allows you to make an independent comparison. Exchange rates are set between pairs of currencies on the world market, not against some arbitrary standard.

You should be asking "which has a higher purchasing power, one dollar or one euro?" THAT question is answered correctly by the first poster. The exchange rate as of 2009-10-16 is €1 = $1.48; i.e. one euro buys about the same amount as 1.48 dollars, so you need more dollars than euros to buy the same amount of goods or services.
