Actually its very simple.
Bits are only 0 and 1 so they are just counted. 1 Mega bit is therefore
With bytes its different. Because one byte is 2^3 Bits they are usually
counted in powers of 2
In the majority of the cases if someone speaks of bits he thinks in
powers of 10 and if he speaks of bytes he thinks in power of 2
As always there are exceptions
1. The classical 1.44M Floppy
2. as already mentioned: Hard Drives because they are "getting bigger"
if their size is given in powers of 10 :-) Bigger harddrives sell
If I was you I would always write KB for 1024 bytes MB for 1024KB. In
other words: since lua has nothing to do with network you will never
need to write in (mega/kilo) bits so always write in power of 2 and
define that in a footnote.
