Hey Rajkumar,

Go to Google and check... you can see more sites for currency converter.

or

If you have/use windows 7 this is very easy for your

go to desktop click right button then go to gadgets
and active currency converter on your desktop(Qatar to India). time to time you can see latest currency rate on your desktop.

till I use this one for converting.
now the latest rate is 1 QR = 15.25
but when you go to any exchange the rate is 15.00
that's mean... what rate show on your computer, just minus .25
that is the correct rate.
Activate now then Enjoy!!
