The only way to get the commonly-used names is to take
1Mbytes as
1024*1000 bytes. There is no justification for this at all.
Justification ? I don't know, but there's an explanation - we

But you can't justify it's 10^3 * 2^10 IMHO.
As I said.

I have an IBM Technical Directory here (a list of all
the PC manuals). It
lists a technical reference manual for '3.5-Inch 720KB/1.44MB Drive'. So
either IBM were just using common names for the device (which is most
unlike IBM), or that's what they called it.
If you want, I can scan th aprobiate pages I found.
I've also got plenty of disks that claim to be
1.44Mbytes.
'classic' disks ? or actual ones - in fact, I looked thru my
disks, and I found that the 1.44 term must have established
around 90/92 - I found no disk stating 1440 K that was labled
later than 1992.
