What unit measures capacitance?

Capacitance is measured in Farads, which is the standard unit of capacitance in the International System of Units (SI). A capacitor's capacitance indicates its ability to store an electric charge per volt applied across its terminals. One Farad is defined as the capability of a capacitor to store one coulomb of charge at one volt.

This measure is critical for understanding how capacitors function in circuits, especially in applications involving timing, filtering, and energy storage. Other units may be used in practical contexts, such as microfarads or picofarads, but they are all derived from the fundamental unit of Farads. The other choices—Ohm, Watt, and Volt—refer to different electrical properties: resistance, power, and electric potential, respectively, and therefore do not relate to the measurement of capacitance.
