Over in the USA they also used to say millimicrofarads for nanofarads.
Micro, nano and pico (and all the other multpliers) are simply ways to avoid having to write lots of zeros. They also conveniently go up and down in thousands.
So:
1000pF = 1nF
1000nF = 1uF
1000uF = 1mF (millfarad, rarely used in practice but it's why you shouldn't use mF to mean microfarads. Just recognise it was often done in the past)
1000mF = 1F (a truly huge capacitor)
1000F = 1kF (Kilo farad? Now we're getting silly)
Al these multipliers, pico, nano, kilo etc can be used for ANY units of measurement. Hence microseconds, kilohms, megawatts, kilometres etc.
