The SI unit of Capacitance is the Farad. It was named after Michael Faraday. It is the charge in coulombs which a capacitor will accept for the potential across it to change by 1 volt.
The Farad was coined by Josiah Latimer Clark in 1861 in honor of Michael Faraday, but it was for a unit of quantity of charge.
An abfarad is an obsolete electromagnetic (CGS) unit of capacitance equal to 109 farads (1,000,000,000 F or 1 GF). This very large unit is used in medical terminology only.
The statfarad was the comparable obsolete electrostatic (CGS) unit of capacitance, and was equal to 1 microfarad.
