This category of measurement units is defined by the "capacitance" type, which is an SI derived quantity.
The SI derived unit for capacitance is the farad.
The farad (symbol F) is the SI unit of capacitance (named after Michael Faraday). A capacitor has a value of one farad when one coulomb of charge causes a potential difference of one volt across it. Its equivalent expressions in other SI units are: Since the farad is a very large unit, values of capacitors are usually expressed in microfarads (?F), nanofarads (nF), or picofarads (pF). The picofarad is comically called a "puff" in laboratory usage.
