Why this formula appears here
The geometric factor Bl appears in both and is eliminated between them: . The BIPM’s mise en pratique is careful about what has just happened: “power of a mechanical nature is equated to power of an electromagnetic nature. The powers are manifestly ‘virtual’ in this method of operation because power does not figure in either mode of this two-mode experiment” [ 4 ] . No power is transferred in either measurement. The equality is between quantities constructed after the fact.
