Puf is slang speech for 10E-12 Farads. However, should only be written as pF.
mmf is micro-micro Farads or 10E-6 X 10E-6 = 10E-12 Farads. Equivalent to pF.
...not to be confused with uF or micro Farads which is just 10E-6 Farads.
Of course, Puf is also a short form for Puffs...a breakfast cereal...Charles must of had 82 puffs in a bowl!
Then again, puf is what you do when take a drag of a cigarette. Didn't know you also smoked?
