The Hobbyking website looks for instance like this with the extension set to convert prices automatically to India  


Chrome Currency Converter is such a tool. The Chrome extension will automatically convert foreign currencies on web pages into a selected one. Supported are 37 different currencies that can be converted with one currency being the base currency that all others are converted to.

The extension detects prices in different formats, updates the currency rates every hour and can display the original prices next to the converted ones.


A mini currency converter is available by pressing Alt-Shift-Ctrl-C, useful to convert prices that are not displayed on a web page

Oh! Thats Very nice tool. It would be more easy to take decisions in terms of price.

Haha! I use that..! Makes it a lot more convenient..!
