K is common as an abbreviation for kilo (=1000) in the metric system. It is
widely used in km and kg among others.

While many online glossaries dedicated to computer jargon such as

http://www.fasterimage.com/faq.htm
http://www.sisnaaz.com/support/DB/glossary.html
http://sislands.com/javascript/appendix/glossary.htm

agree that a KB is 1024 bytes or that it is generally rounded off to 1000,
others do not:

http://data-direct.com/glossary.htm
http://www.pcwebopaedia.com/TERM/K/KB.html

The last in this list explicitly draws a line between data storage Ks
(usually 1024) and data transfer rate Ks (1000).

In any case, it would seem that the usage of K for 1000 (metric system) far
outdates using it for 1024, which is a 20th century development to make
things simple.
