I'd like to ask you all another newb question, with regards to quickly being able to do the math on bitcoin price. Specifically, when you're on the exchange and you're wanting to buy/sell. I'm used to everything being priced in U.S dollars, so I'm having something of a hard time figuring out exactly how much I'm buying. Since the exchanges only deal in the price of bitcoin, and won't tell you how much you're paying in USD.

 
When I go to buy something and I see a price like "0.00000380 BTC" I have a hard time figuring out how much USD I'll be spending to buy x amount of that coin. How do you deal with this? Especially with the constant flux of the price of bitcoin.

 
I found this site, but it won't show you tenths of a cent. It only goes down to $0.01. Is there another site out there which you can do quick conversions of bitcoins to dollars, even if the amount is less than 1 penny?
