Why Kingston micro SD cards are each of different size

Why Kingston micro SD cards are each of different size
When comparing with XP disk properties 2 different 2GB micro SD cards there is a weird difference 1,999,768,128 (1.83GB)
and other 1,999,800,896 (1.83)

When comparing to 3rd Kingston, not micro but 2GB mini SD -
the size appears to be les 1,999,175,680 (1.86GB)
What does it means that size is smaller but GB size is more then micro SD?

Thanks!

Its the way flash memory is managed. You would need to read more on how flash works and "organises" files and the way it handles "bad blocks" .
Most good flash controllers control the flash memory in a dynamic method- making recovery from these beasts a pain in de backside some times.
There might be another cause to this to.. not sure
