There are many websites that constantly update their site with the current conversion rates for currencies around the world. These are good places to look for the exchange rate, then use the equation in Step 3 above to calculate currency totals. You can contact the Department of Treasury or other governmental agencies to get up-to-date information about exchange rates for converting currency. Simply type into a Google search bar what conversion you want to make and Google will tell you the answer using their currency converter.  For example, if you want to know what the exchange rate for $1,000 US to Euros is, type 1000 dollars to euros in any Google search bar and it will tell you the answer. However, because Google's finance converter does not constantly track and update current currency exchange rates, this information is more of an estimate and should not be relied on as accurate up-to-the-minute data.
