By definition, Capacitance is the ratio of Charge and voltage across the element. The unit of the capacitor capacitance is Farad, the symbol is “F”. C=q/V Parallel plate capacitors. Mica capacitors. Electrolytic capacitors. Paper capacitors. Film capacitors. Non-polarized capacitors. power Film capacitors.
The capacitance of the majority of capacitors used in electronic circuits is generally several orders of magnitude smaller than the farad. The most common units of capacitance are the microfarad (μF), nanofarad (nF), picofarad (pF), and, in microcircuits, femtofarad (fF).
Units of capacitance measure the ability of a system to store electrical charge per unit voltage. The standard unit of capacitance is the Farad (F), named after the physicist Michael Faraday. One Farad represents the capacitance of a system when a one-volt potential difference (voltage) results in the storage of one coulomb of electrical charge.
When a voltage V is applied to the capacitor, it stores a charge Q, as shown. We can see how its capacitance may depend on A and d by considering characteristics of the Coulomb force. We know that force between the charges increases with charge values and decreases with the distance between them.

A capacitor is a device used to store electrical charge and electrical energy.
Since capacitance is the charge per unit voltage, one farad is one coulomb per one volt, or 1F = 1C 1V. By definition, a 1.0-F capacitor is able to store 1.0 C of charge (a very large amount of charge) when the potential difference between its plates is only 1.0 V. One farad is therefore a very large capacitance.
