With all due respect, I think you are quite mistaken.  The prefixes 'k' and 
'K' are generally used interchangably.  So are 'm' and 'M' although this
is technically incorrect, since the prefix 'm' means 10^(-3).  In the world of
networking, 'K' means 1000, 'M' means 1000000, and 'G' means 1000000000.
Look through the literature.  The usage is consistent.

There's a thousand places I could point you.  How about this one:
