Not a complaint (I expect the ‘real’ capacity to be less than the stated capacity) – but just wanted to compare to other folks with a 16GB MicroSDHC card – do you also show 14.8GB capacity on it?
It’s very possible.
My 4gb card shows 3.78 before I put anything on it. My netbook at 160gb had really only 140gb (yes really!). I’m not really sure what happens to the rest, but I think just for processing what’s on it.

I have a 16GB player with an actual usable capacity of 14.7 GB, so I think your card is entirely normal. 
To convert the manufacturer’s stated capacity to “real” gigabytes, multiply by 0.93. That won’t give you the exact number, but it’s pretty close.
Yes. Manufacturers advertise a GB as exactly 1,000,000,000 bytes. A true GB has 1,073,741,824 bytes. This is equal to 1024^3. In the 16GB case,
16,000,000,000 / 1024 / 1024 / 1024 = ~14.9 GB
