farad (fărˈəd) [for Michael Faraday], unit of electrical capacitance, equivalent to 1 coulomb of stored charge per volt of applied potential difference.
The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.

the unit of electrical capacitance in the International System of Units and in the meter-kilogram-second-ampere (MKSA) system of units. The symbol for the farad, which was named after M. Faraday, is F. One farad is the capacitance of a capacitor in which a charge of 1 coulomb produces a potential difference of 1 volt between the plates. The unit of capacitance in the centimeter-gram-second (cgs) electrostatic system is 1 cm = (109/c2) F ≈ 1.113 × 10–12F, where c is the numerical value of the speed of light in a vacuum in cm/sec. In practice, the following fractional units are used more frequently than the farad: the microfarad (µLF), which equals 10–6F, and the picofarad (pF), which equals 10–12F.

(electricity)
The unit of capacitance in the meter-kilogram-second system, equal to the capacitance of a capacitor which has a potential difference of 1 volt between its plates when the charge on one of its plates is 1 coulomb, there being an equal and opposite charge on the other plate. Symbolized F.

Physics the derived SI unit of electric capacitance; the capacitance of a capacitor between the plates of which a potential of 1 volt is created by a charge of 1 coulomb.
