There are different type of capacitance meters are available which allows you to measure the capacitance directly between 0.1 Pico farad and 20 microfarads. The unit of capacitance is farad represented by a letter ‘F’. There are several methods to measure the capacitance but the most accurate method is the bridge method.

The unit for measuring capacitance is the farad (F), defined as 1 coulomb (C) of electric charge per volt (V) of potential difference. In practice, the farad is such a large unit that capacitance is usually measured in smaller units such as the microfarad, 1 millionth of a farad; or the nanofarad, 1 billionth of a farad.
The reading of the meter = f*C*V, when f and V are constant the meter reading is linearly proportional to the capacitance of the capacitor. We know that the charge (Q) = CV if we apply fixed voltage then the amount of charge that the capacitor will hold, that depends on the capacitance value of the capacitor.
