Abstract
In the past two years measurements were performed with a watt balance at the National Institute of Standards and Technology (NIST) to determine the Planck constant. A detailed analysis of these measurements and their uncertainties led to a value of h=6.626 069 88(38) x 10^-34 Js. The relative uncertainty is 57 x 10^-9 . This result is 154 x 10^-9 higher than h90Citation
