Why do you think 1m=1024k==131072?  What distance is a kilometer,
how many grams go in a kilogram?

An exception is made for computer memory and disk space because of the
fact that ten address lines with two possible states is possible while
three lines with ten states is next to impossible. 

To make things more complicated:  for diskspace it is common to use
1024 per kilo and 1000kilo per mega.  For memory it is 1024*1024 per mega.

In other words: 1024 per kilo is strange; if it is not common to use it,
use the normal value:1000.  1024 is the exception and this is not used
for line speed.
