Google School: Currency Conversion

Google makes it easy to calculate money conversions from one form of currency to another. For example, you can google for $5 in yen to discover that five dollars is worth about 600 yen.

If you're not sure of the name of a currency, use nationality instead. You can google for 25 Australian money in Italian money. It sounds awkward but it does the job.

You can even convert units in this fashion. Googling for $2.85 per gallon in British money per liter (which turns out to be about 42 pence per liter) provides an international basis for discussing gas prices at the pump.
