Google has a currency conversion feature built in to its search, all you have to do is search for 100 GBP in USD, for example, to convert £100 (UK Pounds Sterling) to US Dollars. If you don’t know the acronym for the currency you’re converting to then don’t worry as you can also do conversions with a search like 100 USD in Czech money, if you were planning a trip to the Czech Republic.

If you have a website, consider joining the Money4Banners advertising network. They will pay you £10 + £5 each month for displaying a small advert on three of your pages, regardless of traffic. American webmasters are welcome, and since £10 == $20, you make more!
