Historic Exchange

I want to calculate different amounts in yen, yuan, euros and other currencies from 2007 to 2011 dollars. Should I use historical rates and simply divide? Or use a current rate? Given the exchange rates at different times, using historical rates be better represented if I'm using it for research. Today I learned that … Very complex due to inflation are buying power of $ 1,000 in 2007 would be $ 750 today currency exchange varies minute by minute, even the purchase cost of living, different food, the quality of the cars, etc call economics the "dismal science" is not real science like physics or chemistry. The results can never predict the "law of supply and demand" is not fixed but can spot trends and make some prediction logic
