Until the rest of the world decided otherwise, I referred to HD disks 
as 1200K and 1440K.  At least that was honest.  The 1.2MB and 1.44MB 
were simply perversions, I assume for shorthand purposes.  

To their credit, as of MS-DOS 6.22, the HELP for FORMAT gives 1440K, 
1200K and 2800K as the *first* of several alternatives for specifying 
capacity.  2K and later drops the "K" forms in the HELP file, but 
FORMAT still accepts them.

So honesty is at least nodded at.
