 This is because that is an odd size 1000mF (10^-6) is rather uncommon 
Hmm... If I'd seen that out of context, I'd have assumed it was 1000
millifarads, not microfarads.  Over here, we'd write that as "1000?F" (if
using ISO 8859-1 or Unicode character set) or possibly "1000uF" ("u"
being
the ASCII character that looks most like "mu") or possibly even
"1000mfd"
(often found on old circuits).

  when standard values and notation came about.  Back
then a 50mF cap was
 a large value!  It was the advent of transistor circuits and their lower
 voltage power supplies that 1000mF were common. Then again we see caps
 now in the full Farad sizes. 
1000mF = 1Farad :-)  But I know what you mean.  I used to have some old
50mfd 450V caps --and they were big, in those days.

  Then again from a womans point of view, it may be that
1400mm sounds
 bigger than 5 and a half inches.  ;) 
Err, I think there's an extra "0" in there somewhere, Allison :-)
