Richard,

A year or two ago, the IEEE proposed a new set of units to handle the 1000
/ 1024 issue.  It  went like this:

1000 = kilo
1024 = kibi

1000000 = mega
1024^2 = mebi

and so forth.

The idea was to use the same two first letters as the 10s unit, but append
"bi" to indicate "binary" units.  So the gigabyte equivalent would be
gibibytes.

I don't think its adoption has been very widespread.  ;-)

>can anyone tell me how TSM calculate 1MB? Is it 1000KB or 1024KB.

Good question.
We'll take Andy's answer as definitive.
Curiously, the TSM manuals say nothing about it.  I've submitted a
request to Publications to have this added.
Note that the issue is somewhat muddied by disk makers basing their
sizings on 1000, whereas software uses 1024.
