Two handy web sites: XE.com and Google for currency conversion. I think Google uses XE, but if you know the shorthands for the currencies, Google can be quicker than messing with drop-downs. As a test, go to Google and enter “1 GBP in INR” (no quotes) to get the number of Indian Rupees in a British Pound. As an aside, Google will also do unit of measurement conversions and maths!
