Hi. Recently I've written a real time bitcoin value calculator.
It's a simple windows console application, that does not only calculate the value of a bitcoin in USD but in all currencies. It works in reverse - you enter your local currency (incl. XAU and XAG - gold and silver oz.) and then the amount you would like to convert and it gives you a real time value + datetime stamp
Values are downloaded and processed in real time, so you know it's accurate. It calculates bitcoin values to the 8-th digit after the comma.

You can check the link in all possible online virus checkers and anti-virus software.
It looks like this:
It's nothing much, but it's easier then going online to look for an accurate price.
Thanks again, and enjoy.
