How to Read a Capacitor: 13 Steps (with Pictures)
Know the units of measurement. The base unit of capacitance is the farad (F). This value is much too large for ordinary circuits, so household capacitors are labeled with one of the following units: 1 µF, uF, or mF = 1 microfarad = 10-6 farads. (Careful — in other contexts, mF is the official abbreviation for millifarads, or 10-3 farads.); 1 nF = 1 nanofarad = 10-9 farads.
