Can anyone tell me how USD is worth in Lindens in Second Life?

I was wondering how much Lindens are worth in USD? Can anyone tell me like from one Lenden to 100,000,000 Lindens?|||it flucuates just like real life currency exchange rates flucuate. You can buy or sell Lindens on secondlife.com. Just enter the amount of Lindens you want to buy or sell and they will return what it will cost in USD or what you will receive in USD.
