How much is 5 kuna worth in US dollars?

Excuse me, I was wondering if you could clarify something for me. I'm a bit confused about the current exchange rate. Specifically, I'm trying to figure out how much 5 kuna from, let's say, Croatia, would be worth in US dollars. I've looked online, but the rates seem to vary quite a bit. Could you possibly give me an estimate or point me in the right direction to find the most accurate information? I appreciate your help in advance.
