Abstract
A new treatment of previously reported results of three electric-unit-dependent fundamental constant experiments carried out at NBS over the last decade or so yields accurate, indirect values in SI units for a number of important quantities. These include the fine-structure constant α, the Avogadro constant N A, the Josephson frequency-voltage ratio 2e/h, and the quantized Hall resistance R H≡h/e 2.Keywords
