The unit of electrical capacitance is the farad (abbreviated F), named after the English physicist and chemist Michael Faraday. The capacitance C of a capacitor is the ratio of the charge Q stored in the capacitor to the applied dc voltage U: C = Q / U.
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).
In the SI system, capacitance is measured in Farads (F). One Farad represents the capacitance of a system when one coulomb of electrical charge is stored per volt of potential difference (voltage) across a capacitor. In simpler terms, it quantifies the ability of a capacitor to store electrical charge relative to the voltage applied to it.

Capacitance is measured in Farads (F), named after the physicist Michael Faraday. It represents the ratio of stored charge to the applied voltage across a capacitor. Understanding capacitance is fundamental in explaining electrical phenomena like energy storage, filtering, and signal processing in electronic circuits.
Dimension formula for Capacitance = Charge x Voltage = [I1T1][M1L2T−3I−1]−1 [I 1 T 1] [M 1 L 2 T − 3 I − 1] − 1 As a result, we will now receive Capacitance Dimensional Formula = [M−1L−2T4I2] [M − 1 L − 2 T 4 I 2] Also learn the difference between capacitor and inductor here.
