The "Farad" is the basic unit used to refer to the quantity of charge a condenser, (modern term is "capacitor") is able to store. a MICRO farad is 1 / 1,000,000 of a farad. a MICRO MICRO farad (now commonly called a pico farad) is 1 / 1,000,000 of a micro farad. So, 110 mmf = 0.000110 mfd. You will find some of us old timers still call a condenser a condenser, and a micro micro farad a micro micro farad, and not the new fangled name. Worse yet, and to ADD to the confusion is the new addition by some fools of the term NANO farad which seems to mean 1 / 1000 of a micro farad, FORSOOTH ! In the saner documentation of the earlier period, however, you will only have to deal with mfd and mmf.
