That is normal from what I have seen. The space is being used by the info the card needs to run. I have 3 16gb cards and after a fresh format I have 14.9gb left on both the class 2 and the class 6

you are seeing 14.8 gb on windows right?

That is correct for a 16gb card

Cards are sold by the bits, but when you format the card that is converted to GB and displayed by windows.

for instance since a kbyte 1024 bits

your 16gb card is actually 15,927,345,152 bits divide that by 1024 , but because of the way it is calculated, you have to divide the result again by 1024 and then once more. You will end up with 14.83349609375 which is how windows sees the GB

EDIT:

Just for reference why you have to divide it 3 times

The first time will give Kbits
Second time will Megabits
Third time will give you Gigabits
