HOW TO QUICKLY CONVERT EUROS TO DOLLARS IN YOUR HEAD
Update November 2013: Here's an easy way to do approximate EUROS to US DOLLAR conversion in your head, at least at the present rate. Whatever the EURO amount is, just add 10%. So, if the EURO is 100, just add 10% of 100 - in other words, just move the decimal place one to the left (10) and you get 110 US DOLLARS. Again, it's presently going to be a little over, and hopefully will continue to be less and less so, but it's a good rough estimate. Let's take another example 30 EUROS: 30 +10% (3) = 33 US DOLLARS.
HOW TO QUICKLY CONVERT DOLLARS TO EUROS IN YOUR HEAD
What about the other way around US DOLLARS (USD) to EUROS? Just subtract 10%. So 100 USD minus 10% (10) = 100 - 10 = about 90 EUROS. What about 45 USD? 45 minus 10% (4.5), = 45 - 4.5 is 40.5 EUROS.
Practice several examples, then check your answer with the CURRENCY CONVERTER above and see how you do.
