The Bureau International des Poids et Mesures (BIPM) is an international organization which works to promote and advance a coherent system of measurements throughout the world, traceable to the International System of Units (SI). One of its activities consists of the dissemination of units and the comparison of national measurement standards, which requires the availability of well-known and well-characterized standards. In particular, in the field of electricity, the BIPM supports capacitance measurements based on a quantum reference, impedance bridges and stable transfer standards, establishing traceability to the defining fundamental constants of the SI. In this paper it will be explained how the farad is realized at the BIPM, including a general description of the measuring systems, and how this unit is maintained.
