Conversion
The euro changeover process in the European Union (EU) Member States is regulated by the EU legislative acts. This regulation is binding for all Member States preparing for the euro changeover.
The conversion rules shall be adopted as one euro expressed in terms of each of the national currencies of the participating Member States.
The conversion rates shall not be rounded or shortened when making conversions. Monetary amounts to be paid or accounted for shall be rounded up or down to the nearest cent. If the application of the conversion rate gives a result which is exactly half-way, the sum shall be rounded up.
