Ron, have to disagree.
I cannot speak for the ham or antique radio community lingo, and the marking on the old capacitors was different from today (then again those were condensers, not caps
) ), but in today's EE practice in the US:
uF - microfarad
mF - not used. 1000uF is what it is.
nF - nanofarad.
pF - picofarad.
In general, in engineering and physics, today:
m - always ""milli", 1/1000
u - always ""micro, 1/1000,000, from its resemblance to Greek "mu" which starts the word "Mikro".
n - always "nano", 1/1,000,000,000
