Not really, more along the lines of:

Insert the euro octane and insert the US octane, and it calculates the difference if any in the ratings....

The US quotes the average of the MON and RON rating, but the EU quotes the RON rating.

Since the MON is about 10 points lower than the RON that means that US "93 octane" is equivalent to EU "98 octane".

So a simple rule of thumb is : add 5 to the US rating and that gives you the equivalent EU rating.
