Here is a tip for those of you who use Windows have not yet found the time to get themselves a Currency Converter Gadget for the desktop.
Go to google and type in the search something like this “100USD to THB”, which will show you in the “suggestion box” how much Thai Baht you get for 100US Dollars, so you do not even have to click search or press enter – the converted values will show up almost instantly while you type!
