What is Triangulation?

Triangulation is the procedure specified in the euro legislation for converting currency of one denomination of the euro into another.

When conversion is between two participating currency units, such as Irish punts and French francs, the triangulation procedure is mandatory.

When the conversion involves a currency not participating in the euro such as UK pounds to French francs direct conversion is allowed, although triangulation is recommended.

There are three steps in triangulation:

1. Convert the first national denomination into the euro. This is done by dividing the amount you want to convert by the euro conversion rate of the first national denomination.

2. Convert the result of step 1 into the second national denomination. This is done by multiplying the result of step 1 by the euro conversion rate of the second national denomination.

3. Round the result to the nearest sub-unit of the second denomination.

Note: Sage Line 50 always round to the 100th unit.
