One mio euro is how much in us dollars?

The value of a Mio euro in US dollars will change with the exchange rate, which was recently about .71 euros per dollar. The prefix Mio is a German abbreviation for Million so at the recent exhange rate there would be about 1.4 Million dollars per 1 Mio Euro. If you have a few MiOS lying about - I would be happy to take them off your hands.
