Compare two currencies using Bitcoin

[Igorzovisk]

There's a way to compare two currencies using bitcoin?
For example: To buy 1 BTC I can use A$1.00 or B$1.50 and A$1.00 buys B$1.00. As we can see, it's better to buy A with B then buy BTC.
What I want to know is if exist a site or somenthing that makes that comparison.

First there is no currency that is 50% cheaper in bitcoin they're all almost identical, like €1=$1.1 and 1BTC=€606=$669
The small deifference will be lost largely in Foreign Exchange fees, so not really interesting.

If A === B (If A is identical to B) then 1BTC is equal to A$1.00 and B$1.00, so it can't be 1BTC equal to B$1.50 because it's not logical. What exactly do you need to compare?
