The capacitance of a capacitor is measured in a unit called the farad. Now, a farad is a pretty big unit, so capacitors used in everyday electronics are usually measured in microfarads (µF), nanofarads (nF), or even picofarads (pF). These smaller units represent a fraction or multiple of a farad, depending on the size of the capacitor.
For large capacitors, the capacitance value and voltage rating are usually printed directly on the case. Some capacitors use "MFD" which stands for "microfarads". ...

In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.

Capacitance Tolerance. The tolerance or ±% rating of a capacitor is part of the "binning" process when capacitors are made. These aren''t always made with high precision methods and the actual values the manufacturers get when they are made can vary, so each capacitor is measured and they are rated for how close they got to the target value.
