Hate to butt in, but according to
<http://physics.nist.gov/cuu/Units/prefixes.html>, 10^3 is kilo, 10^6 is
mega, and 10^9 is giga. These designate decimal multiples and you shouldn't
use them to represent binary multiples. For binary multiples, see
<http://physics.nist.gov/cuu/Units/binary.html>, where 2^10 = 1024 is kibi,
2^20 = 1024 x 1024 = 1048576 is mebi, and 2^30 =1024^3 = 1073741824 is gibi.
