If capacitance is measured in pF, what unit should I use for C?
give me some info on these common engineering unit parings please

The basic unit of capacitance is the farad, but most of them are much smaller than a farad in value. The microfarad (uf) is the next unit down, and a millionth of that is a picofarad (pf). You may hear oldtimers refer to that by the old name of micromicrofarad. In between, and convenient for some values of capacitor, is the nanofarad (10^-9 farads). So you may see a small capacitor listed as 1000 pf, 1 nf, or .001 uf.

In most equations, capacitance is in the very large unit of Farads (F). You will find very few capacitors in this range; their application would be in low to medium voltage and very high current power engineering domain. Most capacitors for electronic device applications will have values in the microFarad (uF), nanoFarads (nF) or picoFarad (pF) ranges, use the multiplying factor of 1x 10^(-6), 1x 10^(-9), or 1 x 10^(-12) respectively to convert their values to Farads for use in equations.
